Sentry is an error tracking and performance monitoring tool. From 24.4.0 until 26.5.2, a Regular Expression Denial of Service (ReDoS) vulnerability exists in Sentry's event ingestion pipeline, where a regex applied to attacker-controlled fields on incoming events can be made to consume disproportionate CPU time. This vulnerability is fixed in 26.5.2.
