description

PHP deployments may be affected by a remote code execution vulnerability. An attacker may be able to execute code remotely where the vulnerable conditions are present, but the supplied evidence does not specify affected versions or the required configuration.

mitigation

Apply the configuration hardening recommended by the PHP security team and MyCERT. Monitor upstream PHP advisories and update promptly when a patched release is published.

automationDeterministic: a check that runs on its own, the same request on every target. Contextual: an agentic technique that needs to be applied per target, for bugs that depend on contextual flows.
contextual
auth requiredWhether an attacker needs an account first, based on the CVSS vector's Privileges Required.
