{"id":"CVE-2026-102663","state":"PUBLISHED","title":"OpenList: Search metadata/count disclosure via Non-Separator-Aware Path Check in Bleve Search","description":"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.","publishedAt":"2026-10-12T18:49:23.454Z","updatedAt":"2026-10-13T16:01:30.361Z","severity":{"score":4.3,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["OpenListTeam OpenList"],"affected":[{"vendor":"OpenListTeam","product":"OpenList","versions":[{"version":"< 4.2.4","status":"affected"}]}],"references":["https://github.com/OpenListTeam/OpenList/security/advisories/GHSA-p6ph-3jx2-3337","https://github.com/OpenListTeam/OpenList/commit/59bd3431408578f420895457554700cc9a52375a","https://github.com/OpenListTeam/OpenList/commit/84ecda35aae2bd0020474086e6ddfd3aa2340679","https://github.com/OpenListTeam/OpenList/releases/tag/v4.2.4"],"weaknesses":["CWE-200","CWE-639"],"ingestedAt":"2026-10-29T20:10:13.529Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/102xxx/CVE-2026-102663.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-102663","state":"PUBLISHED","datePublished":"2026-10-12T18:49:23.454Z","dateUpdated":"2026-10-13T16:01:30.361Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-09-29T15:56:02.102Z"},"containers":{"cna":{"title":"OpenList: Search metadata/count disclosure via Non-Separator-Aware Path Check in Bleve Search","descriptions":[{"lang":"en","value":"OpenList is a file list program that supports multiple storage backends.
