{"id":"CVE-2026-41150","aliases":["GHSA-6m6c-36f7-fhxh"],"url":"https://o3.security/vulnerability/CVE-2026-41150","summary":"Mermaid Gantt Charts are vulnerable to an Infinite Loop DoS","details":"Mermaid is a JavaScript tool that uses Markdown-inspired text to create and modify diagrams and charts. Prior to 10.9.6 and 11.15.0, there is a denial-of-service attack when rendering gantt charts, if they use the excludes attribute to exclude all dates. mermaid.parse is unaffected, unless you then call the ganttDb.getTasks() (which is called when rendering a diagram). This vulnerability is fixed in 10.9.6 and 11.15.0.","published":"2026-05-29T13:54:52.157Z","modified":"2026-08-07T11:51:09.051650127Z","cvss":null,"epss":{"score":0.00384,"percentile":0.31193,"asOf":"2026-08-09"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"mermaid","fixedVersion":"11.15.0"},{"ecosystem":"npm","name":"mermaid","fixedVersion":"10.9.6"}],"fix":{"url":"https://github.com/mermaid-js/mermaid/commit/a59ea56174712ee5430dfd5bc877cb5151f501a6","label":"mermaid-js/mermaid@a59ea56"},"references":[{"type":"WEB","url":"https://github.com/mermaid-js/mermaid/releases/tag/mermaid%4011.15.0"},{"type":"WEB","url":"https://github.com/mermaid-js/mermaid/releases/tag/v10.9.6"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/41xxx/CVE-2026-41150.json"},{"type":"ADVISORY","url":"https://github.com/mermaid-js/mermaid/security/advisories/GHSA-6m6c-36f7-fhxh"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-41150"},{"type":"FIX","url":"https://github.com/mermaid-js/mermaid/commit/a59ea56174712ee5430dfd5bc877cb5151f501a6"},{"type":"FIX","url":"https://github.com/mermaid-js/mermaid/commit/faafb5d49106dd32c367f3882505f2dd625aa30e"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-07T11:51:09.051650127Z"}}
