Affected versions of this package are vulnerable to Arbitrary Code Injection in the parse process. An attacker can execute arbitrary commands on the system by injecting malicious Jinja2 template code into Markdown files or data fields that are subsequently re-parsed and executed without proper sandboxing or validation.
Workaround
This vulnerability can be mitigated by removing MDCleanInclude and MDSectionInclude from the Jinja2 extensions list if markdown includes are not required, auditing included Markdown files for Jinja2 syntax, scanning data sources for template patterns, restricting workspace write access to trusted users, adding a pre-commit hook to block suspicious Jinja2 syntax, and running the application in an isolated container or sandbox in CI/CD pipelines.
