A flaw was found in RPC request using gfs3_symlink_req in glusterfs server which allows symlink destinations to point to file paths outside of the gluster volume.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.68%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
