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.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:N/VI:N/VA:L/SC:N/SI:N/SA:L","score":5.3},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L","score":5.3},"cwes":["CWE-835"],"references":["https://github.com/mermaid-js/mermaid/commit/a59ea56174712ee5430dfd5bc877cb5151f501a6","https://github.com/mermaid-js/mermaid/commit/faafb5d49106dd32c367f3882505f2dd625aa30e","https://github.com/mermaid-js/mermaid/releases/tag/mermaid%4011.15.0","https://github.com/mermaid-js/mermaid/releases/tag/v10.9.6","https://github.com/mermaid-js/mermaid/security/advisories/GHSA-6m6c-36f7-fhxh"],"products":["mermaid_project:mermaid"],"source":"nvd","synced_at":"2026-10-19T22:37:48.043517290+00:00"},"epss":{"cve":"CVE-2026-41150","score":0.00384,"percentile":0.32503,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-6m6c-36f7-fhxh","url":"https://osv.dev/vulnerability/GHSA-6m6c-36f7-fhxh","summary":"Mermaid Gantt Charts are vulnerable to an Infinite Loop DoS","modified":"2026-09-10T03:50:45.806197285Z","packages":[{"ecosystem":"npm","name":"mermaid","purl":"pkg:npm/mermaid","ranges":[">=11.0.0-alpha.1 <11.15.0"],"fixed":["11.15.0"]},{"ecosystem":"npm","name":"mermaid","purl":"pkg:npm/mermaid","ranges":["<10.9.6"],"fixed":["10.9.6"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
