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.","state":0,"publishedAt":"2026-10-12T18:49:23.454+00:00","modifiedAt":"2026-10-13T16:01:30.361+00:00","affected":[{"ecosystem":"Vendor product","name":"OpenList","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"OpenListTeam\",\n                    \"product\": \"OpenList\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 4.2.4\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N","score":4.3,"severity":"MEDIUM"}],"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"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-102663","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-102663","identifiers":["CVE-2026-102663"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
