CVE-2026-77522: CWE-918: Server-Side Request Forgery (SSRF) in 1Panel-dev MaxKB
CVE-2026-77522 is a Server-Side Request Forgery (SSRF) vulnerability in MaxKB, an open-source AI assistant for enterprise. Versions 2.10.3-lts and earlier allow an authenticated user to supply URLs that the server fetches without proper validation or restrictions. This enables low-privileged users to access internal HTTP services or cloud metadata through the MaxKB server. No official fix is currently available.
AI Analysis
Technical Summary
MaxKB versions up to 2.10.3-lts contain an SSRF vulnerability where the knowledge web-document import and synchronization crawler passes user-supplied URLs to Fork.fork, which uses requests.get with verify=False and lacks restrictions on URL schemes or internal network addresses. This allows an authenticated workspace user to cause the server to make arbitrary HTTP requests to internal or cloud metadata endpoints, potentially exposing sensitive information. The vulnerability is tracked as CWE-918. As of the latest review, no patched version exists.
Potential Impact
An authenticated low-privileged user can exploit this SSRF vulnerability to read internal HTTP services or cloud metadata accessible from the MaxKB server. This could lead to information disclosure within the internal network or cloud environment. The CVSS score is 4.3 (medium severity), indicating limited impact primarily on confidentiality with no direct integrity or availability effects.
Mitigation Recommendations
No official patch or fix is currently available for this vulnerability. Users should monitor vendor advisories for updates. Until a fix is released, restrict access to trusted users and consider network-level controls to limit the MaxKB server's ability to reach sensitive internal or cloud metadata endpoints.
