CVE-2022-24803Public exploitNetwork attack vector

Host command execution via malformed include target

Published Mar 31, 2022 · Updated Apr 22, 2025

Command injection in Jakub Jirutka Asciidoctor Include Extension before 0.4.0 allows remote attackers to execute OS commands via crafted AsciiDoc. The IncludeProcessor URI check lets a line break bypass remote-target validation, leaving a pipe-prefixed include target for IO.foreach or URI.open to execute as an operating-system command. Reachability requires an application to render attacker-controlled AsciiDoc with allow-uri-read enabled; commands run with the renderer's privileges.
