{"id":"AZL-88394","summary":"CVE-2026-44896 affecting package python-mistune for versions less than 3.2.1-1","details":"Mistune is a Python Markdown parser with renderers and plugins. In 3.2.0 and earlier, in src/mistune/directives/image.py, the render_figure() function concatenates figclass and figwidth options directly into HTML attributes without escaping. This allows attribute injection and XSS even when HTMLRenderer(escape=True) is used, because these values bypass the inline renderer. Version 3.2.1 contains a patch.","modified":"2026-08-28T17:47:37.646222120Z","published":"2026-05-26T21:16:39Z","upstream":["CVE-2026-44896"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-44896"}],"affected":[{"package":{"name":"python-mistune","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/python-mistune"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.2.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-88394.json"}}],"schema_version":"1.9.0"}
