CVE-2026-108596
OpenLIT 2.1.0 contains an authorization bypass vulnerability that allows authenticated users to read other projects' telemetry by supplying a forged x-openlit-project-id header.
Does this matter?
Lower severity and a low EPSS score (0.30%). Track it; it rarely justifies an emergency change on its own.
