Because Python-Markdown does not catch this exception, any application that processes attacker-controlled Markdown may crash. This enables remote, unauthenticated Denial of Service in web applications, documentation systems, CI/CD pipelines, and any service that renders untrusted Markdown. The issue was acknowledged by the vendor and fixed in version 3.8.1. This issue causes a remote Denial of Service in any application parsing untrusted Markdown, and can lead to Information Disclosure through uncaught exceptions."},{"lang":"es","value":"Python-Markdown versión 3.8 contiene una vulnerabilidad donde secuencias malformadas similares a HTML pueden hacer que html.parser.HTMLParser genere un AssertionError no manejado durante el análisis de Markdown. Debido a que Python-Markdown no captura esta excepción, cualquier aplicación que procese Markdown controlado por el atacante puede fallar. Esto permite una denegación de servicio remota y no autenticada en aplicaciones web, sistemas de documentación, pipelines de CI/CD y cualquier servicio que renderice Markdown no confiable. El problema fue reconocido por el proveedor y corregido en la versión 3.8.1. Este problema causa una denegación de servicio remota en cualquier aplicación que analice Markdown no confiable, y puede llevar a la revelación de información a través de excepciones no capturadas."}],"metrics":{"cvssMetricV31":[{"source":"nvd@nist.gov","type":"Primary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","baseScore":7.5,"baseSeverity":"HIGH","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"NONE","integrityImpact":"NONE","availabilityImpact":"HIGH"},"exploitabilityScore":3.9,"impactScore":3.6},{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","baseScore":7.5,"baseSeverity":"HIGH","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"NONE","integrityImpact":"NONE","availabilityImpact":"HIGH"},"exploitabilityScore":3.9,"impactScore":3.6}]},"weaknesses":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","type":"Secondary","description":[{"lang":"en","value":"CWE-400"}]}],"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:a:python-markdown:markdown:3.8:*:*:*:*:python:*:*","matchCriteriaId":"2F64C314-46AB-44B9-87F4-69C31A94FC8E"}]}]}],"references":[{"url":"https://github.com/Python-Markdown/markdown","source":"cve@mitre.org","tags":["Product"]},{"url":"https://github.com/Python-Markdown/markdown/actions/runs/15736122892","source":"cve@mitre.org","tags":["Product"]},{"url":"https://github.com/Python-Markdown/markdown/issues/1534","source":"cve@mitre.org","tags":["Exploit","Issue Tracking"]},{"url":"http://www.openwall.com/lists/oss-security/2026/03/06/4","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Mailing List","Third Party Advisory"]}]}}]}
