This link is maintained to preserve external references.\n\n## Original Description\nMistune before 3.3.0 contains a path traversal vulnerability in the Include directive that allows attackers to read arbitrary files by supplying ../ sequences in include paths. Attackers can also inject HTML through unescaped error messages and included file contents to perform cross-site scripting even when escape=True is set.\n\n## Affected packages\n\n- `mistune < 3.3.0`\n\n## Remediation\n\nRefer to the advisory for the patched release.","depth":"twilight","depthScore":41,"depthScoreParts":{"impact":41.3,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
