{"id":"CVE-2026-77523","summary":"MaxKB: Cross-workspace model parameter form write","details":"MaxKB is an open-source AI assistant for enterprise. In version 2.10.3-lts and earlier, the model parameter form route authorizes the path workspace but ModelSerializer.ModelParams loads and saves a Model by id alone without including workspace_id in the query. An authenticated user with model read permission in an attacker-controlled workspace can supply a known victim model_id to read or overwrite the victim's model_params_form in another workspace, potentially altering workflows that use those defaults. No fixed version is available as of this review.","aliases":["GHSA-g888-8cvh-9284"],"modified":"2026-09-24T03:30:32.664017493Z","published":"2026-09-21T20:39:36.806Z","database_specific":{"cwe_ids":["CWE-639"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/77xxx/CVE-2026-77523.json","cna_assigner":"GitHub_M"},"references":[{"type":"ADVISORY","url":"https://github.com/1Panel-dev/MaxKB/security/advisories/GHSA-g888-8cvh-9284"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/77xxx/CVE-2026-77523.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-77523"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/1panel-dev/maxkb","events":[{"introduced":"0"},{"last_affected":"dcab5d0ef4275756ce9fc1f63360f241fe7adc1c"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"last_affected":"2.10.3-lts"}],"source":"AFFECTED_FIELD"}}],"versions":["v2.10.3-lts","v2.10.1-lts","v2.10.0-lts","v2.9.2","v2.9.1","v2.9.0","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-2026-77523.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:L"}]}
