GHSA-mgwc-m57j-46w8 PUBLISHED CVSS 9.800000190734863 CRITICAL

Record from GitHub Advisory Database · Published May 14, 2022

The client in OpenSSH before 7.2 mishandles failed cookie generation for untrusted X11 forwarding and relies on the local X11 server for access-control decisions, which allows remote X11 clients to trigger a fallback and obtain trusted X11 forwarding privileges by leveraging configuration issues on this X11 server, as demonstrated by lack of the SECURITY extension on this X11 server.
