{"id":"GHSA-8cqv-vvq2-6p8c","summary":"Duplicate Advisory: Mistune: Path Traversal and XSS in Include directive","details":"## Duplicate Advisory\n\nThis advisory has been withdrawn because it is a duplicate of GHSA-h7ww-273w-6cm8. 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even when escape=True is set.","modified":"2026-10-23T21:00:04.307837522Z","published":"2026-10-22T21:32:36Z","withdrawn":"2026-10-23T20:46:28Z","database_specific":{"github_reviewed_at":"2026-10-23T20:46:28Z","nvd_published_at":"2026-10-22T19:17:41Z","cwe_ids":["CWE-22"],"severity":"HIGH","github_reviewed":true},"references":[{"type":"WEB","url":"https://github.com/lepture/mistune/security/advisories/GHSA-h7ww-273w-6cm8"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-115355"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/mistune-before-3.3.0-path-traversal-and-xss-via-include-directive"}],"affected":[{"package":{"name":"mistune","ecosystem":"PyPI","purl":"pkg:pypi/mistune"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.1.0","0.2.0","0.3.0","0.3.1","0.4","0.4.1","0.5","0.5.1","0.6","0.7","0.7.1","0.7.2","0.7.3","0.7.4","0.8","0.8.1","0.8.2","0.8.3","0.8.4","2.0.0","2.0.0a1","2.0.0a2","2.0.0a3","2.0.0a4","2.0.0a5","2.0.0a6","2.0.0rc1","2.0.1","2.0.2","2.0.3","2.0.4","2.0.5","2.1.0","3.0.0","3.0.0a1","3.0.0a2","3.0.0a3","3.0.0rc1","3.0.0rc2","3.0.0rc3","3.0.0rc4","3.0.0rc5","3.0.1","3.0.2","3.1.0","3.1.1","3.1.2","3.1.3","3.1.4","3.2.0","3.2.1","3.3.0","3.3.1","3.3.2","3.3.3","3.3.4","3.4.0"],"database_specific":{"last_known_affected_version_range":"\u003c 3.3.0","source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/10/GHSA-8cqv-vvq2-6p8c/GHSA-8cqv-vvq2-6p8c.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N"},{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X"}]}
