CVE-2026-119723
validatingZero is analyzing and reversing it now.description
HHVM releases before 23c061f4e804a51badd5f85227e65185651253b5 mishandle certain nested HTTP request parameters. A remote unauthenticated attacker can cause the HHVM server process to terminate before the hosted application handles the request, provided they can send GET or POST requests to the service.
Still under analysis: more detail becomes available as the pipeline runs.
mitigation
Upgrade HHVM to a release containing 23c061f4e804a51badd5f85227e65185651253b5. Until upgraded, restrict untrusted access to endpoints served by HHVM where feasible.
