Sentry: Unsafe pickle deserialization in Relocation Feature

Published: Sep 22, 2026Updated: Sep 24, 2026 Sources: CVE List NVDCWE-502

N/ACVSS

NVD MITRE

Description

Sentry is an error tracking and performance monitoring tool. From 23.11.0 until 26.7.0, Sentry instances with the relocation feature enabled unsafely deserialize a legacy database field while importing a user-supplied relocation archive. An authenticated user can craft an archive that causes arbitrary code execution in the import worker process. Self-hosted installations using the default configuration are not affected because the relocation feature is disabled by default. This issue is fixed in version 26.7.0.
