It does this by resolving the requested URL to an absolute path and then checking that path relative to the root. However, these checks are not performed when looking for compressed variants in the `FileResponse` class, and symbolic links are then automatically followed when performing `Path.stat()` and `Path.open()` to send the file. ### Impact Servers with static routes that contain compressed variants as symbolic links, pointing outside the root directory, or that permit users to upload or create such links, are impacted. ---- Patch: [aio-libs/aiohttp#8653 --- ### Release Notes <details> <summary>aio-libs/aiohttp (aiohttp)</summary> ### [`v3.10.2`](https://redirect.github.com/aio-libs/aiohttp/blob/HEAD/CHANGES.rst#3102-2024-08-08) [Compare Source](https://redirect.github.com/aio-libs/aiohttp/compare/v3.10.1...v3.10.2) \=================== ## Bug fixes - Fixed server checks for circular symbolic links to be compatible with Python 3.13 -- by :user:`steverep`. *Related issues and pull requests on GitHub:* :issue:`8565`. - Fixed request body not being read when ignoring an Upgrade request -- by :user:`Dreamsorcerer`. *Related issues and pull requests on GitHub:* :issue:`8597`. - Fixed an edge case where shutdown would wait for timeout when the handler was already completed -- by :user:`Dreamsorcerer`. *Related issues and pull requests on GitHub:* :issue:`8611`. - Fixed connecting to `npipe://`, `tcp://`, and `unix://` urls -- by :user:`bdraco`. *Related issues and pull requests on GitHub:* :issue:`8632`. - Fixed WebSocket ping tasks being prematurely garbage collected -- by :user:`bdraco`. There was a small risk that WebSocket ping tasks would be prematurely garbage collected because the event loop only holds a weak reference to the task.
