{"id":"CVE-2026-48070","summary":"Docmost: Avatar URL path traversal in avatar cleanup leads to arbitrary local file deletion","details":"Docmost is open-source collaborative wiki and documentation software. Prior to 0.80.1, authenticated users can store attacker-controlled avatarUrl values that are later reused by avatar cleanup without confinement to the intended directory on local-storage deployments. A low-privileged user can cause deletion of arbitrary local files or directories reachable by the Docmost service account. This issue is fixed in version 0.80.1.","aliases":["GHSA-95f8-h5hf-8248"],"modified":"2026-09-26T03:45:53.636185112Z","published":"2026-09-24T18:15:58.700Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/48xxx/CVE-2026-48070.json","cna_assigner":"GitHub_M","cwe_ids":["CWE-22"]},"references":[{"type":"WEB","url":"https://github.com/docmost/docmost/releases/tag/v0.80.1"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/48xxx/CVE-2026-48070.json"},{"type":"ADVISORY","url":"https://github.com/docmost/docmost/security/advisories/GHSA-95f8-h5hf-8248"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-48070"},{"type":"FIX","url":"https://github.com/docmost/docmost/commit/a573acedd0317f3472cb0f8b95f6aa15315312e5"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/docmost/docmost","events":[{"introduced":"0"},{"fixed":"a573acedd0317f3472cb0f8b95f6aa15315312e5"},{"fixed":"980521f95792ddd382ebbc275467a8319a351bae"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"0.80.1"}],"source":["AFFECTED_FIELD","REFERENCES"]}}],"versions":["v0.70.2","v0.70.1","v0.71.1","v0.71.0","v0.70.3","v0.70.0","v0.25.3","v0.25.2","v0.25.1","v0.25.0","v0.25.0-beta.1","v0.24.1","v0.24.0","v0.23.2","v0.23.1","v0.23.0","v0.22.2","v0.22.1","v0.22.0","v0.21.0","v0.20.4","v0.20.3","v0.20.2","v0.20.1","v0.20.0","v0.10.2","v0.10.1","v0.10.0","v0.9.0","v0.8.4","v0.8.3","v0.8.2","v0.8.1","v0.8.0","v0.7.0","v0.6.2","v0.6.1","v0.6.0","v0.5.0","v0.4.1","v0.4.0","v0.3.1","v0.3.0","v0.2.10","v0.2.9","v0.2.8","v0.2.7","v0.2.5","v0.2.4","0.2.3","v0.2.2","v0.2.1","v0.2.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-48070.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:L"}]}
