CVE-2026-109619 RCE via stale global state

Tillverkarens beskrivning (engelska)

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.

Multiple strategies can trigger this condition and produce remote code execution (RCE).
