## Technical details

A vulnerability exists in Weblate's webhook endpoint due to improper validation of syntactic correctness in input (CWE-1286). By sending a crafted webhook payload, an unauthenticated remote attacker can trigger repository updates across multiple repositories and enumerate internal components. The issue stems from an over-permissive endpoint that does not sufficiently restrict the scope of actions triggered by incoming webhook data. This vulnerability is addressed in version 5.15; a temporary workaround is to disable webhooks entirely using the ENABLE_HOOKS setting.
