BREW-ADVAI-CLI-CVE-2025-69229 (GHSA-G84X-MCQJ-X9QQ)
Vulnerability from osv_homebrew – Published: 2026-08-13 16:35 – Updated: 2026-09-09 23:40 – Source websiteSummary
Handling of chunked messages can result in excessive blocking CPU usage when receiving a large number of chunks.
Impact
If an application makes use of the request.read() method in an endpoint, it may be possible for an attacker to cause the server to spend a moderate amount of blocking CPU time (e.g. 1 second) while processing the request. This could potentially lead to DoS as the server would be unable to handle other requests during that time.
