GHSA-JJ3X-WXRX-4X23 AIOHTTP vulnerable to DoS when bypassing asserts

Summary When assert statements are bypassed, an infinite loop can occur, resulting in a DoS attack when processing a POST body. Impact If optimisations are enabled -O or PYTHONOPTIMIZE=1, and the application includes a handler that uses the Request.post method, then an attacker may be able to...

Infinite loop

Overview Affected versions of this package are vulnerable to Infinite loop in the Request.post function. An attacker can cause the application to exhaust system resources by sending a POST request. Note: This is only exploitable if Python optimizations are enabled using the -O flag or setting...

Overview Affected versions of this package are vulnerable to Information Exposure over the /static endpoint. An attacker can determine the existence of internal path components by sending requests to probe for absolute path elements. Remediation Upgrade aiohttp to version 3.13.3 or higher...

AIOHTTP vulnerable to brute-force leak of internal static file path components

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 ascertai...
