Prior to version 1.0.0-beta.25, tinyagentos (taOS) registers all system settings routes under a single APIRouter() instance created with no admin authorization dependency. Any authenticated user—including non-admin invited users whose is_admin flag is explicitly False—can read the full system configuration, overwrite it, modify platform settings, trigger a git pull + dependency reinstall + service restart, and switch the tracked update branch. Successful exploitation of the write endpoints causes immediate configuration corruption or a denial of service for all users on the instance from a low-privileged account. This issue has been patched in version 1.0.0-beta.25.","epss":null,"exploits":[],"kev":null,"metrics":[{"score":8.3,"severity":"high","source":"CNA: GitHub_M","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:H/A:H","version":"3.1"}],"modifiedAt":1794433573292,"publishedAt":1794433573292,"references":[{"source":"CNA: GitHub_M","tags":["x_refsource_CONFIRM"],"url":"https://github.com/jaylfc/taOS/security/advisories/GHSA-47g9-fwwp-hrfp"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/jaylfc/taOS/commit/6e65dd7ddd4b973e326d7ccb0ec74e8eef65374b"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/jaylfc/taOS/releases/tag/v1.0.0-beta.25"}],"remediation":[],"revision":"97eb4db08c582f8743fdf4c589424b68d879f1c9d67f923213446982b5f5136c","sources":[{"modifiedAt":1794433573292,"name":"CNA: GitHub_M","retrievedAt":1794435084632,"url":"https://www.cve.org/CVERecord?id=CVE-2026-67548"}],"ssvc":null,"status":"published","title":"taOS: Non-Admin Users Can Access System Settings and Update Actions","updatedAt":1794435084632}
