CVE-2026-109619
This CVE is being exploited. Apply the vendor fix, or take the service off the internet until you can, then check your logs for attempts.
What it is
PHP has various global state that temporarily points into request memory. In some scenarios, global state may not be correctly reset, or may be repopulated after being reset. The global state may then refer to request memory even after it has been freed. Subsequent requests may read or branch on this stale state before it is fully initialized. Multiple strategies can trigger this condition and produce remote code execution (RCE).

Questions
Is CVE-2026-109619 being exploited in the wild?
Yes. The huntback decoy network captured 110 exploitation attempts from 1 distinct source IPs; the most recent was on 2026-11-11. It is also in the CISA KEV catalogue.
Can CVE-2026-109619 be detected on the network?
Yes. huntback carries a network signature for CVE-2026-109619, so attempts against a decoy are tagged in real time.
How huntback helps
Deploy a decoy that emulates Amis Ts and you will see every attempt at this CVE the moment it lands, with the full payload, the attacker's infrastructure, and any stage-2 loader. Then huntback can scan the attacker back.
