Example: ``` gantt excludes monday,tuesday,wednesday,thursday,friday,saturday,sunday DoS :2025-01-01, 1d ``` `mermaid.parse` is unaffected, unless you then call the `ganttDb.getTasks()` (which is called when rendering a diagram). ##### Patches This has been patched in: - [v11.15.0](https://github.com/mermaid-js/mermaid/releases/tag/mermaid%4011.15.0) (see [faafb5d49106dd32c367f3882505f2dd625aa30e](mermaid-js/mermaid@faafb5d)) - [v10.9.6](https://github.com/mermaid-js/mermaid/releases/tag/v10.9.6) (see [a59ea56174712ee5430dfd5bc877cb5151f501a6](mermaid-js/mermaid@a59ea56)) ##### Workarounds There are no workarounds available without updating to a newer version of mermaid. #### Severity - CVSS Score: 5.3 / 10 (Medium) - Vector String: `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` #### References - [https://github.com/mermaid-js/mermaid/security/advisories/GHSA-6m6c-36f7-fhxh](https://github.com/mermaid-js/mermaid/security/advisories/GHSA-6m6c-36f7-fhxh) - [https://github.com/mermaid-js/mermaid/commit/a59ea56174712ee5430dfd5bc877cb5151f501a6](https://github.com/mermaid-js/mermaid/commit/a59ea56174712ee5430dfd5bc877cb5151f501a6) - [https://github.com/mermaid-js/mermaid/commit/faafb5d49106dd32c367f3882505f2dd625aa30e](https://github.com/mermaid-js/mermaid/commit/faafb5d49106dd32c367f3882505f2dd625aa30e) - [https://github.com/mermaid-js/mermaid](https://github.com/mermaid-js/mermaid) - [https://github.com/mermaid-js/mermaid/releases/tag/mermaid%4011.15.0](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/releases/tag/v10.9.6) This data is provided by [OSV](https://osv.dev/vulnerability/GHSA-6m6c-36f7-fhxh) and the [GitHub Advisory Database](https://github.com/github/advisory-database) ([CC-BY 4.0](https://github.com/github/advisory-database/blob/main/LICENSE.md)). </details> --- ### Mermaid: Improper sanitization of configuration leads to CSS injection [CVE-2026-41159](https://nvd.nist.gov/vuln/detail/CVE-2026-41159) / [GHSA-87f9-hvmw-gh4p](GHSA-87f9-hvmw-gh4p) <details> <summary>More information</summary> #### Details ##### Impact Mermaid's default configuration allows injecting CSS that applies outside of the Mermaid diagram via the `fontFamily`, `themeCSS`, and `altFontFamily` configuration options. Live demo: [mermaid.live](https://mermaid.live/edit#pako:eNpNjktLxDAUhf9KvFBR6JS-60QQfODKlUvJ5k6TtsEmKTHFGUP-u-mI6Nmdy3fOPR56wwVQSBIvtXSUeAaD0e4ZlZxPDChhcLxFfwiEauOuLq_9Afv30ZpVczpaITS5kGox1qF2gfSeBwYhJAnThAyz-ewntI68vG5-0z3Z7e7IA9OQwmglB-rsKlJQwircLPgNZeAmocTPAi4GXGfHgOkQYwvqN2PUbzJuGSegA84f0a0LRyeeJI4W_xChubCPcbQD2pwbgHo4Aq2aKmvbqq3zoiu7pizqFE6RybN9VFfFY1HWXRVS-Dr_zLObrt7_V_gGGXZlGg) Example code: ``` %%{init: {"fontFamily": "x;a{b} :not(&){background:green !important} c{d}"}}%% flowchart LR A --> B ``` The injected CSS exploits stylis's `&` (scope reference) handling. `:not(&)` escapes the `#mermaid-xxx` automatic scoping, applying styles to all page elements. Global at-rules (`@font-face`, `@keyframes`, `@counter-style`) are also injectable as stylis hoists them to top level. This allows page defacement and DOM attribute exfiltration via CSS `:has()` selectors. ##### Patches - [v11.15.0](https://github.com/mermaid-js/mermaid/releases/tag/mermaid%4011.15.0) (see [64769738d5b59211e1decb471ffbaca8afec51aa](mermaid-js/mermaid@6476973)) - [v10.9.6](https://github.com/mermaid-js/mermaid/releases/tag/v10.9.6) (see [a9d9f0d8eb790349121508688cd338253fd80d76](mermaid-js/mermaid@a9d9f0d)) ##### Workarounds If you can't upgrade mermaid, you can set the [`secure`](https://mermaid.js.org/config/schema-docs/config.html#secure) config value in the mermaid config to avoid allowing diagrams to modify `fontFamily`, `themeCSS`, `altFontFamily`, and `themeVariables`. Setting [`"securityLevel": "sandbox"`](https://mermaid.js.org/config/schema-docs/config.html#securitylevel) will also prevent this. ##### Credits Reported by @​zsxsoft on behalf of @​KeenSecurityLab #### Severity -

Previously the lexer only matched ASCII `[A-Za-z]+` for text tokens, even though the grammar referenced `UNICODE_TEXT`. Bare Chinese, Japanese, Korean, emoji, and accented Latin characters in labels caused a parse error.
