CVE-2026-64870: 1panel-Dev Maxkb

Medium severity, CVSS 5.3. EPSS: 0.4% chance of exploitation in the next 30 days.

MaxKB is an open-source AI assistant for enterprise. In versions 2.0.0 through 2.10.4-lts, UpdateStoreTool.update_tool passes caller-supplied download_url and download_callback_url values to requests.get without equivalent trusted-host and redirect validation, allowing an authenticated workspace user to make the server request internal, loopback, link-local, or cloud metadata URLs. A fix is present on the v2 branch but has not yet been included in a published release.

Affected products

• 1panel-Dev Maxkb: from 2.0.0, up to and including 2.10.4-lts
