{"cve":"CVE-2026-102663","nvd":{"published":"2026-10-12T19:16:36.190","modified":"2026-10-13T17:17:14.363","status":"Deferred","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.","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:N/A:N","score":4.3},"cwes":["CWE-200","CWE-639"],"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","https://github.com/OpenListTeam/OpenList/security/advisories/GHSA-p6ph-3jx2-3337"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:58:52.678897993+00:00"},"epss":{"cve":"CVE-2026-102663","score":0.0026,"percentile":0.17487,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-p6ph-3jx2-3337","url":"https://osv.dev/vulnerability/GHSA-p6ph-3jx2-3337","summary":"OpenList: Search metadata/count disclosure via Non-Separator-Aware Path Check in Bleve Search","modified":"2026-10-13T10:55:40.368699040Z","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-2026-6113","url":"https://osv.dev/vulnerability/GO-2026-6113","summary":"OpenList: Search metadata/count disclosure via Non-Separator-Aware Path Check in Bleve Search in github.com/OpenListTeam/OpenList","modified":"2026-10-13T10:55:40.368699040Z","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).
