CVE-2012-5534
The hook_process function in the plugin API for WeeChat 0.3.0 through 0.3.9.1 allows remote attackers to execute arbitrary commands via shell metacharacters in a command from a plugin, related to "shell expansion."
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (4.44%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
