description

Apache FOP through version 2.11 may create temporary files with unsafe permissions. This can permit unintended access to temporary-file contents; the advisory does not specify the attacker preconditions.

mitigation

Upgrade Apache FOP to version 2.12.

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.
