CVE-2026-47728

Description

Bugsink is a self-hosted error tracking tool. Prior to 2.2.0, Bugsink resolved sourcemaps and debug files by debug ID without scoping that lookup to the project that owned the uploaded metadata. An authenticated user with access to one project could cause event processing in that project to use sourcemap/debug-file metadata uploaded for another project in the same Bugsink instance, if the same debug ID was referenced. This vulnerability is fixed in 2.2.0.
