CISA adds critical PHP2Shell vulnerabilities to KEV catalog

Topographic elevation contour card for CISA adds critical PHP2Shell vulnerabilities to KEV catalog

What happened.CISA added two critical PHP2Shell remote code execution vulnerabilities affecting global PHP web runtimes to its Known Exploited Vulnerabilities catalog.

Why it matters.Production web backends process external client requests directly through interpreter runtimes. When core execution components fail before web application firewalls inspect payload bodies, perimeter controls fail completely. Engineering leaders must upgrade to PHP versions 8.5.12, 8.4.27, 8.3.36, or 8.2.35 immediately. Teams should examine web gateway logs for abnormal process execution.
