GHSA-63hw-fmq6-xxg2 on CTRL-OS 26.05

Aliases: GHSA-63hw-fmq6-xxg2, CVE-2026-54277

Packages: python3Packages.aiohttp

Status: Plausible

Advisory Information

Summary

It is possible to bypass the max_line_size check in parts of an HTTP request in the C parser.

Impact

If using the optimised C parser (the default in pre-built wheels), then an attacker may be able to send oversized lines through the HTTP parser and use an excessive amount of memory, potentially leading to DoS.
