EchelonGraph scoreMEDIUM confidence

This critical-severity CVE scores 10.0 under NVD CVSS v3. EPSS exploit probability: 2.7%, top 16% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

Asciidoctor-include-ext is Asciidoctor’s standard include processor reimplemented as an extension. 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. This attack is possible even when allow-uri-read is disabled! The problem has been patched in the referenced commits.
