{"schema":"threatline.record/2","record":{"id":"CVE-2026-102663","aliases":["GHSA-p6ph-3jx2-3337","GO-2026-6113"],"summary":"OpenList: Search metadata/count disclosure via Non-Separator-Aware Path Check in Bleve Search","details":"OpenList is a file list program that supports multiple storage backends. Prior to 4.2.4, the OpenList search API uses a non-separator-aware strings.HasPrefix comparison as a path containment authorization check when authorizing globally indexed Bleve results against a restricted user's BasePath. When Bleve search is enabled and a restricted authenticated user searches the global index for content in a sibling path, the user causes a globally indexed sibling-path result to pass the prefix check. The strings.HasPrefix(node.Parent, user.BasePath) predicate allows a sibling path such as /base2 to be treated as contained by /base. Unauthorized file metadata or file-existence information can be disclosed, and the backend Total value can reveal a match even when another access check removes the individual result. This issue is fixed in version 4.2.4.","categories":["Libraries & packages"],"product":"OpenList","vendor":"OpenListTeam","ecosystem":"Go","affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-102663","source_modified_at":"2026-10-13T16:01:30.361Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"OpenList","vendor":"OpenListTeam","versions":[{"version":"< 4.2.4","status":"affected"}],"defaultStatus":null},{"source":"OSV","source_url":"https://osv.dev/vulnerability/GHSA-p6ph-3jx2-3337","source_modified_at":"2026-10-13T10:55:40.368699040Z","fetched_at":"2026-10-23T18:48:36.087640Z","package":{"name":"github.com/OpenListTeam/OpenList/v4","ecosystem":"Go","purl":"pkg:golang/github.com/OpenListTeam/OpenList/v4"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"4.2.4"}]}],"versions":[]}],"fixed_versions":[{"source":"OSV","source_url":"https://osv.dev/vulnerability/GHSA-p6ph-3jx2-3337","source_modified_at":"2026-10-13T10:55:40.368699040Z","fetched_at":"2026-10-23T18:48:36.087640Z","package":{"name":"github.com/OpenListTeam/OpenList/v4","ecosystem":"Go","purl":"pkg:golang/github.com/OpenListTeam/OpenList/v4"},"version":"4.2.4"}],"cvss":4.3,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.00211,"percentile":0.10786,"score_date":"2026-10-23"},"published_at":"2026-10-12T18:49:23.454Z","modified_at":"2026-10-13T16:01:30.361Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-102663","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-13T16:01:30.361Z"},{"source":"OSV","url":"https://osv.dev/vulnerability/GHSA-p6ph-3jx2-3337","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-13T10:55:40.368699040Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-102663","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","OSV","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/OpenListTeam/OpenList/security/advisories/GHSA-p6ph-3jx2-3337","tags":["exploit"]},{"source":"CVE List","url":"https://github.com/OpenListTeam/OpenList/commit/59bd3431408578f420895457554700cc9a52375a","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/OpenListTeam/OpenList/commit/84ecda35aae2bd0020474086e6ddfd3aa2340679","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/OpenListTeam/OpenList/releases/tag/v4.2.4","tags":["x_refsource_MISC"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"poc","automatable":"no","technical_impact":"partial","assessed_at":"2026-10-13T16:00:59.279006Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":"ecosystem","confidence":"heuristic","reviewed":false},"change_timestamp":"2026-10-13T16:01:30.361Z","content_hash":"d6c6416aa1c0fa6cdaec66e3dbd0293b8d48e5b3f1c099f766832a587125eeaa"}}
