{"id":"CVE-2026-83803","summary":"Sentry: Unsafe pickle deserialization in Relocation Feature","details":"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.","aliases":["GHSA-xm86-7c47-gjm4"],"modified":"2026-09-24T03:47:01.111525763Z","published":"2026-09-22T16:24:13.720Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-502"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/83xxx/CVE-2026-83803.json"},"references":[{"type":"WEB","url":"https://github.com/getsentry/sentry/releases/tag/26.7.0"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/83xxx/CVE-2026-83803.json"},{"type":"ADVISORY","url":"https://github.com/getsentry/sentry/security/advisories/GHSA-xm86-7c47-gjm4"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-83803"},{"type":"FIX","url":"https://github.com/getsentry/sentry/commit/d7fd44193c282102f9fcd2c73973820f3d10ac3a"},{"type":"FIX","url":"https://github.com/getsentry/sentry/pull/119622"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/getsentry/sentry","events":[{"introduced":"dfdf4fb44be269dc25db5b2a34374eefee3c36f5"},{"fixed":"d7fd44193c282102f9fcd2c73973820f3d10ac3a"},{"fixed":"279c0c4b6a73518ec9d070309703c8d0abdd58e9"}],"database_specific":{"extracted_events":[{"introduced":"23.11.0"},{"fixed":"26.7.0"}],"source":["AFFECTED_FIELD","REFERENCES"]}}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-83803.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N"}]}
