Sentry: Inefficient Regular Expression Complexity in sentry_CVE-2026-52794

7.5 / 10

HIGH

CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H

Description

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.
