CVE-2024-40075Network attack vector

Authenticated service interruption via undisclosed XML parsing

Published Jul 22, 2024 · Updated Dec 2, 2024

XXE in Laravel 11.x allows remote authenticated users to interrupt an application service through crafted XML input. The published record identifies no Laravel component, XML parsing entry point, or operation that resolves attacker-controlled external entities. The published assessment limits impact to reduced availability, while the sole referenced proof of concept instead documents an unrelated PHP deserialization gadget chain.
