PHP2Shell Is the PHP Engine Flaw Hiding Under Clean App Code
CVE-2026-109618 and CVE-2026-109619 show why runtime patching belongs in every application security review.
- Patch PHP runtimes to the fixed versions CISA lists, prioritizing internet-facing systems first.
- Inventory PHP wherever it may be embedded in other software, not just named application servers.
- Treat interpreter flaws as application security events, because runtime bugs can bypass clean app code.
