"summary": "### Summary\nA bug in the build process allows any unauthenticated user to read parts of the server source code.\n\n### Details\nDuring build, along with client assets such as css and font files, the sourcemap files **for the server code** are moved to a publicly-accessible folder.\nhttps://github.com/withastro/astro/blob/176fe9f113fd912f9b61e848b00bbcfecd6d5c2c/packages/astro/src/core/build/static-build.ts#L139\n\nAny outside party can read them with an unauthorized HTTP GET request to the same server hosting the rest of the website.\n\nWhile some server files are hashed, making their access obscure, the files corresponding to the file system router (those in `src/pages`) are predictably named. For example. the sourcemap file for `src/pages/index.astro` gets named `dist/client/pages/index.astro.mjs.map`.\n\n### PoC\nHere is one example of an affected open-source website:\nhttps://creatorsgarten.org/pages/index.astro.mjs.map\n\n<image width=\"500\" height=\"263\" src=\"https://github.com/user-attachments/assets/773c5532-87af-42b8-838e-8f5472bf9f68\"/>\n\nThe file can be saved and opened using https://evanw.github.io/source-map-visualization/ to reconstruct the source code.\n\n<image width=\"500\" height=\"271\" src=\"https://github.com/user-attachments/assets/7d35d0ca-3a29-4666-be21-cfefe311ac9d\"/>\n\nThe above accurately mirrors the source code as seen in the repository: https://github.com/creatorsgarten/creatorsgarten.org/blob/main/src/pages/index.astro\n\n<image width=\"500\" height=\"298\" src=\"https://github.com/user-attachments/assets/39e77197-8382-4556-a024-c526dacccc1c\"/>\n\n\nThe above was found as the 4th result (and the first one on Astro 5.0+) when making the following search query on GitHub.com ([search results link](https://github.com/search?q=path%3Aastro.config.mjs+%40sentry%2Fastro&type=code)):\n```\npath:astro.config.mjs @sentry/astro\n```\n\nThis vulnerability is the root cause of https://github.com/withastro/astro/issues/12703, which links to a simple stackblitz project demonstrating the vulnerability. Upon build, notice the contents of the `dist/client` (referred to as `config.build.client` in astro code) folder. All astro servers make the folder in question accessible to the public internet without any authentication. It contains `.map` files corresponding to the code that runs on the server.\n\n### Impact\nAll **server-output** (SSR) projects on Astro 5 versions **v5.0.3** through **v5.0.6** (inclusive), that have **sourcemaps enabled**, either directly or through an add-on such as [sentry](https://github.com/getsentry/sentry-javascript/blob/develop/packages/astro/src/integration/index.ts#L50), are affected. The fix for **server-output** projects was released in **astro@5.0.7**.\n\nAdditionally, all **static-output** (SSG) projects built using Astro 4 versions **4.16.17 or older**, or Astro 5 versions **5.0.7 or older**, that have **sourcemaps enabled** are also affected. The fix for **static-output** projects was released in **astro@5.0.8**, and backported to Astro v4 in **astro@4.16.18**.\n\nThe immediate impact is limited to source code. Any secrets or environment variables are not exposed unless they are present verbatim in the source code.\n\nThere is no immediate loss of integrity within the the vulnerable server. However, it is possible to subsequently discover another vulnerability via the revealed source code .\n\nThere is no immediate impact to availability of the vulnerable server. However, the presence of an unsafe regular expression, for example, can quickly be exploited to subsequently compromise the availability.\n\n- Network attack vector.\n- Low attack complexity.\n- No privileges required.\n- No interaction required from an authorized user.\n- Scope is limited to first party. Although the source code of closed-source third-party software may also be exposed. \n\n### Remediation\nThe fix for **server-output** projects was released in **astro@5.0.7**, and the fix for **static-output** projects was released in **astro@5.0.8** and backported to Astro v4 in **astro@4.16.18**. Users are advised to update immediately if they are using sourcemaps or an integration that enables sourcemaps.",
