CVE-2026-39418: CWE-918: Server-Side Request Forgery (SSRF) in 1Panel-dev MaxKBCVE-2026-39418 0 CVE-2026-39418 is a Server-Side Request Forgery (SSRF) vulnerability in MaxKB versions 2. 7. 1 and below. The issue arises because the sandbox network protection can be bypassed using the socket. sendto() function with the MSG_FASTOPEN flag, allowing authenticated users with tool-editing permissions to access internal services blocked by the sandbox. This bypass occurs because the sandbox hooks the connect() function to block banned IPs, but sendto() with MSG_FASTOPEN establishes TCP connections without calling connect(), circumventing IP validation. The vulnerability has been fixed in MaxKB version 2. 8. 0. The CVSS score is 5. Join the discussion | CVE Database V5 | 04/14/2026, 00:08:50 UTC Added: 04/14/2026, 01:16:56 UTC |
