{"cve":"CVE-2026-73509","nvd":{"published":"2026-08-13T15:20:17.623","modified":"2026-09-18T20:09:01.757","status":"Deferred","description":"OpenList a file list program that supports multiple storage. Prior to 4.2.4, the authenticated /api/fs/batch_rename handler in server/handles/fsbatch.go authorizes only the source directory produced by user.JoinPath(req.SrcDir) and validates renameObject.NewName with checkRelativePath, but does not validate attacker-controlled renameObject.SrcName, supplied as src_name, before concatenating it with the authorized path and passing the result to fs.Rename. A user with rename permission can use traversal segments in src_name to make path normalization select a file outside the authorized directory and configured base path, resulting in cross-user file integrity loss, limited availability impact, and file-existence disclosure through success or error responses. This issue is fixed in version 4.2.4.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:H/A:L","score":7.6},"cwes":["CWE-22"],"references":["https://github.com/OpenListTeam/OpenList/commit/651da18da4c647d96648d4bb64462baac1c37e04","https://github.com/OpenListTeam/OpenList/releases/tag/v4.2.4","https://github.com/OpenListTeam/OpenList/security/advisories/GHSA-95cv-r8x4-vh75","https://github.com/OpenListTeam/OpenList/security/advisories/GHSA-95cv-r8x4-vh75"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:48:17.459049833+00:00"},"epss":{"cve":"CVE-2026-73509","score":0.00522,"percentile":0.44319,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-95cv-r8x4-vh75","url":"https://osv.dev/vulnerability/GHSA-95cv-r8x4-vh75","summary":"OpenList: Authenticated users can rename files outside their base path via batch rename `src_name` traversal","modified":"2026-08-18T15:11:01.965471770Z","packages":[{"ecosystem":"Go","name":"github.com/OpenListTeam/OpenList/v4","purl":"pkg:golang/github.com/OpenListTeam/OpenList/v4","ranges":["<4.2.4"],"fixed":["4.2.4"]}]},{"id":"GO-2026-6110","url":"https://osv.dev/vulnerability/GO-2026-6110","summary":"OpenList: Authenticated users can rename files outside their base path via batch rename `src_name` traversal in github.com/OpenListTeam/OpenList","modified":"2026-08-18T15:00:16.049131895Z","packages":[{"ecosystem":"Go","name":"github.com/OpenListTeam/OpenList","purl":"pkg:golang/github.com/OpenListTeam/OpenList","ranges":["all versions"],"fixed":[]},{"ecosystem":"Go","name":"github.com/OpenListTeam/OpenList/v3","purl":"pkg:golang/github.com/OpenListTeam/OpenList/v3","ranges":["all versions"],"fixed":[]},{"ecosystem":"Go","name":"github.com/OpenListTeam/OpenList/v4","purl":"pkg:golang/github.com/OpenListTeam/OpenList/v4","ranges":["<4.2.4"],"fixed":["4.2.4"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
