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":"2026-10-12T19:16:36.19+00:00","modifiedAt":"2026-10-13T17:17:14.363+00:00","affected":[],"metrics":[{"system":"CVSS 3.1 · security-advisories@github.com · Secondary","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/commit/59bd3431408578f420895457554700cc9a52375a","https://github.com/OpenListTeam/OpenList/commit/84ecda35aae2bd0020474086e6ddfd3aa2340679","https://github.com/OpenListTeam/OpenList/releases/tag/v4.2.4","https://github.com/OpenListTeam/OpenList/security/advisories/GHSA-p6ph-3jx2-3337"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-102663","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Deferred","weaknesses":["CWE-200","CWE-639"],"productCriteria":[],"sourceDates":{"published":"2026-10-12T19:16:36.190","lastModified":"2026-10-13T17:17:14.363"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
