{"id":"CVE-2026-44847","summary":"MaxKB: Webhook Trigger Authentication Bypass","details":"MaxKB is an open-source AI assistant for enterprise. Prior to 2.9.0, MaxKB's webhook trigger endpoint (/api/trigger/v1/webhook/{trigger_id}) is accessible without authentication. The WebhookAuth class unconditionally returns (None, {}), which Django REST Framework interprets as successful authentication. Combined with optional per-trigger token verification and no backend enforcement of token requirements, any unauthenticated attacker who knows a valid trigger ID can invoke webhook triggers to execute their bound tasks. This vulnerability is fixed in 2.9.0.","aliases":["GHSA-r3j3-j58q-rjpp"],"modified":"2026-07-08T08:13:29.511496825Z","published":"2026-05-26T20:16:46.794Z","database_specific":{"cna_assigner":"GitHub_M","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/44xxx/CVE-2026-44847.json","cwe_ids":["CWE-287","CWE-306"]},"references":[{"type":"ADVISORY","url":"https://github.com/1Panel-dev/MaxKB/security/advisories/GHSA-r3j3-j58q-rjpp"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/44xxx/CVE-2026-44847.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-44847"},{"type":"REPORT","url":"https://github.com/1Panel-dev/MaxKB/issues/5213"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/1panel-dev/maxkb","events":[{"introduced":"0"},{"fixed":"e0fe160afb4ff524d4122b90fbad948669f755f7"}],"database_specific":{"source":"AFFECTED_FIELD","extracted_events":[{"introduced":"0"},{"fixed":"2.9.0"}]}}],"versions":["v2.8.1","v2.8.0","v2.7.0","v2.6.1","v2.6.0","v2.5.0","v2.4.0","v2.3.0","v2.2.0","v2.1.0","v2.0.2","v2.0.1","v2.0.0","v1.10.4-lts","v1.10.3-lts","v1.10.2-lts","v1.10.1-lts","v1.10.0-lts","v1.9.0","v1.7.0","v1.6.1","v1.6.0","v1.5.0","v1.4.0","v1.3.0","v1.2.1","v1.2.0","v1.1.3","v1.1.2","v1.1.1","v1.1.0","v1.0.1","v1.0.0","v0.9.1","v0.9.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-44847.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N"}]}
