CVE-2022-24803
Versions prior to 0.4.0, when used to render user-supplied input in AsciiDoc markup, may allow an attacker to execute arbitrary system commands on the host operating system.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.76%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
