{"id":"CVE-2026-67449","summary":"Portabase: Unauthenticated path traversal in TUS webhook overwrites AES-256-GCM master key","details":"Portabase is a database backup and restore tool for PostgreSQL, MySQL, MsSQL, MariaDB, Firebird SQL, SQLite, MongoDB, Redis, Files and Docker Volume. Prior to version 1.21.2, a path traversal in the TUS upload webhook handler (app/api/tus/hooks/route.ts) allowed an unauthenticated attacker to overwrite arbitrary files under the private data directory, including /data/private/keys/master_key.bin (the AES-256-GCM master key). This issue has been patched in version 1.21.2.","aliases":["GHSA-7697-vf3j-253j"],"modified":"2026-11-13T02:47:36.425943563Z","published":"2026-11-11T21:51:23.105Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-22","CWE-306"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/67xxx/CVE-2026-67449.json","unresolved_ranges":[{"extracted_events":[{"range":[{"fixed":"1.21.2"}],"source":"AFFECTED_FIELD","strategy":"StringRangeExpression"}]},{"extracted_events":[{"range":[{"fixed":"1.21.2"},{"fixed":"1.21.2"}],"source":"DESCRIPTION"}]}]},"references":[{"type":"WEB","url":"https://github.com/Portabase/portabase/releases/tag/1.21.2"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/67xxx/CVE-2026-67449.json"},{"type":"ADVISORY","url":"https://github.com/Portabase/portabase/security/advisories/GHSA-7697-vf3j-253j"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-67449"},{"type":"FIX","url":"https://github.com/Portabase/portabase/commit/8dcb406790728fbdbf758ec88bf000af79498fc1"},{"type":"FIX","url":"https://github.com/Portabase/portabase/pull/355"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/portabase/portabase","events":[{"introduced":"0"},{"fixed":"8dcb406790728fbdbf758ec88bf000af79498fc1"},{"fixed":"9c2359e87b1f274ed094c7e7f36eaafe86ce355d"}],"database_specific":{"extracted_events":[{"source":"REFERENCES_COMMIT","range":[{"fixed":"8dcb406790728fbdbf758ec88bf000af79498fc1"}]},{"range":[{"fixed":"9c2359e87b1f274ed094c7e7f36eaafe86ce355d"}],"source":"REFERENCES_TAG","original_tag":"1.21.2"}]}}],"versions":["1.21.0","1.21.1","1.20.7","1.20.6","1.20.3","1.20.2","1.20.1","1.20.0","1.19.0","1.18.4","1.18.3","1.18.2","1.18.1","1.18.0","1.17.4","1.17.3","1.17.2","1.17.1","1.15.5","1.17.0","1.16.2","1.16.1","1.16.0","1.15.4","1.15.3","1.15.2","1.15.1","1.15.0","1.14.1","1.14.0","1.13.1","1.13.0","1.12.1","1.12.0","1.11.5","1.11.4","1.11.3","1.11.2","1.11.1","1.11.0","1.10.0","1.9.5","1.9.4","1.9.3","1.9.2","1.9.1","1.9.0","1.8.0","1.7.1","1.7.0","1.6.1","1.6.0","1.5.4","1.5.3","1.5.2","1.5.1","1.5.0","1.4.56","1.4.55","1.4.54","1.4.53","1.4.52","1.4.51","1.4.46","1.4.45","1.4.44","1.4.43","v1.4.42","v1.4.41","v1.4.40","v1.4.39","v1.4.38","v1.4.37","v1.4.36","v1.4.35","v1.4.34","v1.4.33","v1.4.32","v1.4.31","v1.4.30","v1.4.29","v1.4.28","v1.4.27","v1.4.26","v1.4.25","v1.4.24","v1.4.23","1.4.22","1.4.21","1.4.20","1.4.19","1.4.18","1.4.17","1.4.16","1.4.15","1.4.14","1.4.13","1.4.12","1.4.11","1.4.10","1.4.9","1.4.8","1.4.7","1.4.5","1.4.4","1.4.3","1.4.2","1.4.1","1.3.0","1.4.0","1.3.0-rc.1","1.2.9","1.2.8","1.2.7","1.2.6","1.2.5","1.2.4","1.2.3","1.2.2","1.2.1","1.2.0","1.1.12-rc.4","1.1.12-rc.3","1.1.12-rc.2","1.1.12-rc.1","1.1.11-rc.2","1.1.11-rc.1","1.1.10","1.1.9","1.1.8","1.1.8-rc.2","1.1.8-rc.1","1.1.7-rc.1","1.1.7","1.1.6-rc.2","1.1.6","1.1.6-rc.1","1.1.5","1.1.5-rc.5","1.1.5-rc.4","1.1.5-rc.3","1.1.5-rc.2","1.1.5-rc.1","1.1.4","1.1.4-rc.3","1.1.4-rc.2","1.1.4-rc.1","1.1.3-rc.3","1.1.3-rc.2","1.1.3-rc.1","1.1.2","1.1.2-rc.3","1.1.2-rc.2","1.1.2-rc.1","1.1.1","1.1.1-rc.1","1.1.0","1.0.0-migration-rc.6","1.0.0-migration-rc.5","1.0.0-migration-rc.4","1.0.0-migration-rc.3","1.0.0-migration-rc.2","1.0.0-migration-rc.1","1.0.0-rc.6","1.0.0-rc.5","1.0.0-rc.4","1.0.0-rc.3","1.0.0-rc.2","1.0.0-rc.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-67449.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
