CVE-2022-33124

Disputed service interruption via invalid IPv6 URL

Published Jun 22, 2022 · Updated Aug 3, 2024

Invalid IPv6 URL handling in aiohttp 3.8.1 raises ValueError and is reported to allow attackers to interrupt a calling service. The sole upstream report contains no description or reproducer, so no code locus or untrusted-input path has been established. The upstream maintainers reject the claim as invalid, while the CVE record notes that common callers handle the exception and that no denial-of-service context has been demonstrated.
