description

A reported PHP flaw may allow remote code execution when an affected application processes attacker-controlled input. An attacker must be able to send such input to a vulnerable PHP deployment; affected versions are not specified in the supplied evidence.

mitigation

Apply the PHP security update as soon as the emergency release is available. Until then, reduce exposure by limiting public access to PHP applications and restricting untrusted input paths where operationally possible.

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.
