MEDIUM5.3EPSS 0.05%AIOHTTP vulnerable to brute-force leak of internal static file path components
Published: 1/5/2026Modified: 2/4/2026
Description
### Summary Path normalization for static files prevents path traversal, but opens up the ability for an attacker to ascertain the existence of absolute path components. ### Impact If an application uses `web.static()` (not recommended for production deployments), it may be possible for an attacker to ascertain the existence of path components. ------ Patch: https://github.com/aio-libs/aiohttp/commit/f2a86fd5ac0383000d1715afddfa704413f0711e
