PHP2Shell: GitLab helps find and remediate critical PHP flaws

GitLab states that GitLab.com, GitLab Self-Managed, GitLab Dedicated, and GitLab-managed infrastructure are not affected by the critical PHP2Shell vulnerabilities, CVE-2026-109618 and CVE-2026-109619, because GitLab does not use PHP to serve web requests. The flaws, fixed by the PHP project on October 21, 2026 and rated 9.2 CVSS v4.0, affect the PHP engine before application code executes, potentially allowing unauthenticated remote code execution on PHP-serving web servers such as Apache and NGINX. Organizations running PHP should urgently update every relevant host and container to fixed PHP releases or distribution-provided patched packages, rebuild and redeploy container images, and restart PHP processes. The guidance recommends combining GitLab container scanning, Orbit, code search, and independent runtime inventories to identify affected projects and deployed workloads, while noting that package-based scanning may miss PHP compiled from source or included in official images. GitLab Duo tools can help organize remediation and enforce scanning or approval policies, but human review remains necessary to confirm actual runtime exposure. Because exploitation reports emerged before and after disclosure, organizations with internet-facing vulnerable PHP servers should review logs and systems from October 17 onward, preserve evidence before restarts where compromise is suspected, isolate affected servers, and rotate credentials or secrets accessible to PHP processes.
