{"id":"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.","aliases":["GHSA-6m6c-36f7-fhxh"],"modified":"2026-07-15T01:49:06.110290678Z","published":"2026-05-29T13:54:52.157Z","related":["CGA-8jpw-2g7x-w3h9"],"database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-835"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/41xxx/CVE-2026-41150.json"},"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"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/mermaid-js/mermaid","events":[{"introduced":"0"},{"fixed":"dd351a7cef45b70638147a5e000f1ee8bfd35637"},{"introduced":"2cfdd1620a8ceef37c0b738569dfb8bcc0005547"},{"fixed":"41646dfd43ac83f001b03c70605feb036afae46d"},{"fixed":"a59ea56174712ee5430dfd5bc877cb5151f501a6"},{"fixed":"faafb5d49106dd32c367f3882505f2dd625aa30e"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"10.9.6"},{"introduced":"11.0.0"},{"fixed":"11.15.0"}],"source":["CPE_RANGE","REFERENCES"],"cpe":"cpe:2.3:a:mermaid_project:mermaid:*:*:*:*:*:node.js:*:*"}}],"versions":["@mermaid-js/parser@1.1.1","@mermaid-js/layout-tidy-tree@0.2.2","mermaid@11.14.0","@mermaid-js/tiny@11.14.0","@mermaid-js/parser@1.1.0","@mermaid-js/examples@1.2.0","v10.9.5","mermaid@11.13.0","@mermaid-js/tiny@11.13.0","@mermaid-js/parser@1.0.1","@mermaid-js/layout-elk@0.2.1","@mermaid-js/examples@1.1.0","mermaid@11.12.3","@mermaid-js/tiny@11.12.3","@mermaid-js/parser@1.0.0","@mermaid-js/layout-tidy-tree@0.2.1","mermaid@11.12.2","mermaid@11.12.1","@mermaid-js/tiny@11.12.1","v10.9.4","@mermaid-js/parser@0.6.3","mermaid@11.12.0","@mermaid-js/tiny@11.12.0","mermaid@11.11.0","@mermaid-js/tiny@11.11.0","@mermaid-js/layout-tidy-tree@0.2.0","@mermaid-js/layout-elk@0.2.0","mermaid@11.10.1","@mermaid-js/tiny@11.10.1","mermaid@11.10.0","@mermaid-js/tiny@11.10.0","@mermaid-js/mermaid-zenuml@0.2.2","@mermaid-js/layout-elk@0.1.9","v10.9.3","mermaid@11.8.1","@mermaid-js/tiny@11.8.1","@mermaid-js/parser@0.6.1","mermaid@11.8.0","@mermaid-js/tiny@11.8.0","@mermaid-js/parser@0.6.0","mermaid@11.7.0","@mermaid-js/tiny@11.7.0","@mermaid-js/parser@0.5.0","@mermaid-js/mermaid-zenuml@0.2.1","@mermaid-js/layout-elk@0.1.8","mermaid@11.6.0","@mermaid-js/parser@0.4.0","mermaid@11.5.0","@mermaid-js/layout-elk@0.1.7","mermaid@11.4.1","@mermaid-js/layout-elk@0.1.6","mermaid@11.4.0","mermaid@11.3.0","@mermaid-js/layout-elk@0.1.5","v10.9.1","v10.9.2","mermaid@11.2.1","@mermaid-js/layout-elk@0.1.4","mermaid@11.2.0","mermaid@11.1.1","mermaid@11.1.0","@mermaid-js/parser@0.3.0","@mermaid-js/layout-elk@0.1.3","@mermaid-js/layout-elk@0.1.2","mermaid@11.0.2","@mermaid-js/parser@0.2.0","@mermaid-js/layout-elk@0.1.1","mermaid@11.0.1","v11.0.0","v10.9.0","v10.7.0","v10.4.0","v10.3.0","v10.1.0","9.1.5","9.1.3","9.1.2","8.13.11","8.13.10","8.13.7","8.13.6","8.13.5","8.12.1","8.11.4","8.11.3","8.11.0-rc2","8.9.3","8.9.1","8.8.3","8.8.0","8.7.0","8.6.2","8.6.0","8.5.2","untagged-566ebfbf21141b604025","8.5.1","untagged-31c93788afe260d914bb","8.4.8","untagged-7651dabb407ecd5631ce","8.4.6","untagged-f43366252632a1a42020","8.4.4","8.2.0","8.3.0","8.2.6","8.2.5","8.2.4","8.2.3","8.2.2","8.1.0","8.2.1","7.0.5","7.0.3","7.0.2","7.0.0","6.0.0","0.5.7","0.5.6","0.5.5","0.5.4","0.5.3","0.5.2","0.5.1","0.5.0","0.4.0","0.3.5","0.3.4","0.3.3","0.3.2","0.3.1","0.3.0","0.2.16","0.2.15","0.2.14","0.2.13","0.2.8","0.2.7","0.2.6","0.2.5","0.2.4","0.2.3","0.2.2","0.2.1","0.2.0","0.1.1","0.1.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-41150.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V4","score":"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"}]}
