Official PHP security advisory released on 21 Oct 2026 reports two critical
unauthenticated Remote Code Execution vulnerabilities:
1. CVE-2026-109618 (RCE via OOM corruption):
- Out-of-memory handling can interrupt PHP while internal request data
is only partially initialized.
- Mitigation: set 'memory_limit = -1' to avoid controllable PHP internal
OOM failure, with conservative 'post_max_size = 32M' and 'upload_max_filesize = 30M'.
2. CVE-2026-109619 (RCE via stale global state):
- Request-owned internal state can survive after its backing memory has
been freed, allowing subsequent requests handled by the same worker
to reuse stale state.
- Mitigation: disable 'session.upload_progress.enabled = 0', and for PHP 8.5
set 'fatal_error_backtraces = 0'.
