CVE-2026-119233
validatingZero is analyzing and reversing it now.GHSA-pw3q-x446-986c ↗EUVD-2026-123603 ↗
description
proxygen versions before v2026.11.09.00 are affected by uncontrolled buffering and repeated processing of incomplete HTTP/3 non-DATA frames. An unauthenticated remote HTTP/3 peer can cause excessive memory and CPU consumption, resulting in denial of service, by sending a large declared frame incrementally.
Still under analysis: more detail becomes available as the pipeline runs.
mitigation
Upgrade proxygen to v2026.11.09.00 or later. Restrict untrusted HTTP/3 access until the upgrade is complete.
fixed in v2026.11.09.00
outcome
Run in progress: no artifact yet.
