Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-102663 exists.\n\nAffected packages and fixed versions:\n- github.com/OpenListTeam/OpenList/v4 (Go): affected all versions; fixed in 4.2.4\n- github.com/OpenListTeam/OpenList/v4 (Go): affected all versions; fixed in 4.2.4\n- github.com/OpenListTeam/OpenList/v4 (Go): affected all versions; fixed in 4.2.4\n- github.com/OpenListTeam/OpenList (Go): affected all versions; no fix listed\n- github.com/OpenListTeam/OpenList/v3 (Go): affected all versions; no fix listed\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-102663/ (Markdown: https://insights.sbomify.com/CVE-2026-102663/index.md)","id":"CVE-2026-102663","markdown":"https://insights.sbomify.com/CVE-2026-102663/index.md","name":"CVE-2026-102663","record":{"aliases":["GHSA-p6ph-3jx2-3337","GO-2026-6113"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":true,"product_category":"OpenList file manager","requires_auth":"low_privilege","summary":"A restricted user can leak file metadata and existence information from sibling paths due to a flawed path containment check in the search API.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":4.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-639","name":"Authorization Bypass Through User-Controlled Key"},{"id":"CWE-200","name":"Exposure of Sensitive Information to an Unauthorized Actor"}],"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.","ecosystems":["Go"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":true,"headline":"OpenList: Search metadata/count disclosure via Non-Separator-Aware Path Check in Bleve Search","id":"CVE-2026-102663","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Go","product":null,"products":[],"type":"information_disclosure","year":"2026"},"n_packages":5,"n_references":4,"next":{"headline":"Joyland AI hard-coded credentials for push notifications","id":"CVE-2026-102666"},"packages":[{"ecosystem":"Go","fixed":[],"introduced":["0"],"last_affected":[],"package":"github.com/OpenListTeam/OpenList","purl":"pkg:golang/github.com/OpenListTeam/OpenList","source":"GO-2026-6113"},{"ecosystem":"Go","fixed":[],"introduced":["0"],"last_affected":[],"package":"github.com/OpenListTeam/OpenList/v3","purl":"pkg:golang/github.com/OpenListTeam/OpenList/v3","source":"GO-2026-6113"},{"ecosystem":"Go","fixed":["4.2.4"],"introduced":["0"],"last_affected":[],"package":"github.com/OpenListTeam/OpenList/v4","purl":null,"source":"GHSA-p6ph-3jx2-3337"},{"ecosystem":"Go","fixed":["4.2.4"],"introduced":["0"],"last_affected":[],"package":"github.com/OpenListTeam/OpenList/v4","purl":"pkg:golang/github.com/OpenListTeam/OpenList/v4","source":"GHSA-p6ph-3jx2-3337"},{"ecosystem":"Go","fixed":["4.2.4"],"introduced":["0"],"last_affected":[],"package":"github.com/OpenListTeam/OpenList/v4","purl":"pkg:golang/github.com/OpenListTeam/OpenList/v4","source":"GO-2026-6113"}],"prev":{"headline":"Burrito: Unauthenticated webhooks trigger unauthorized Terraform plans when webhookSecret is unset","id":"CVE-2026-102649"},"products":["OpenList"],"published":"2026-10-12","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"CC BY 4.0","name":"Go Vulnerability Database","prefix":"GO"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-10-13","vendors":["OpenListTeam"]},"summary":"A restricted user can leak file metadata and existence information from sibling paths due to a flawed path containment check in the search API.","url":"https://insights.sbomify.com/CVE-2026-102663/"}
