6.9 mediumEPSS 0.4%

Medium (6.9) in php frankenphp. EPSS 0.4% estimated probability of exploitation activity in the next 30 days.

On this page
FrankenPHP before 1.13.2 contains a resource exhaustion vulnerability that allows unauthenticated clients to tie up PHP threads because queued requests are not cancelled when clients disconnect. Attackers can send many requests and close connections immediately, forcing handleRequestWithRegularPHPThreads and worker handlers to execute them and delay all clients sharing the thread pool.
