{"id":"CVE-2026-28790","aliases":["GHSA-4fqm-6fmh-82mq","GO-2026-4587"],"url":"https://o3.security/vulnerability/CVE-2026-28790","summary":"OliveTin: Unauthenticated Action Termination via KillAction When Guests Must Login","details":"OliveTin gives access to predefined shell commands from a web interface. Prior to version 3000.11.0, OliveTin allows an unauthenticated guest to terminate running actions through KillAction even when authRequireGuestsToLogin: true is enabled. Guests are correctly blocked from dashboard access, but can still call the KillAction RPC directly and successfully stop a running action. This is a broken access control issue that causes unauthorized denial of service against legitimate action executions. This issue has been patched in version 3000.11.0.","published":"2026-03-05T19:34:53.951Z","modified":"2026-08-07T11:50:44.014620648Z","cvss":{"score":7.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"github.com/OliveTin/OliveTin","fixedVersion":"0.0.0-20260302002902-d9804182eae4"}],"fix":{"url":"https://github.com/OliveTin/OliveTin/commit/d9804182eae43cf49f735e6533ddbe1541c2b9a9","label":"OliveTin/OliveTin@d980418"},"references":[{"type":"WEB","url":"https://github.com/OliveTin/OliveTin/releases/tag/3000.11.0"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/28xxx/CVE-2026-28790.json"},{"type":"ADVISORY","url":"https://github.com/OliveTin/OliveTin/security/advisories/GHSA-4fqm-6fmh-82mq"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-28790"},{"type":"FIX","url":"https://github.com/OliveTin/OliveTin/commit/d9804182eae43cf49f735e6533ddbe1541c2b9a9"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-07T11:50:44.014620648Z"}}
