Hi, The following vulnerability was published for pymdown-extensions. CVE-2025-68142[0]: | PyMdown Extensions is a set of extensions for the `Python-Markdown` | markdown project. Versions prior to 10.16.1 have a ReDOS bug found | within the figure caption extension (`pymdownx.blocks.caption`). In | systems that take unchecked user content, this could cause long | hanges when processing the data if a malicious payload was crafted. | This issue is patched in Release 10.16.1. As a workaround, those who | process unknown user content without timeouts or other safeguards in | place to prevent really large, malicious content being aimed at | systems may avoid the use of `pymdownx.blocks.caption` until they're | able to upgrade. If you fix the vulnerability please also make sure to include the CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
