There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - Mermaid is a JavaScript tool that uses Markdown-inspired text to create and modify diagrams and charts.
    Versions 10.9.5 and prior, in addition to 11.0.0-alpha.1 through 11.12.0 are vulnerable to CSS injection
    through improper sanitization. The state diagram (and any other diagram type that routes user-controlled
    style strings through the createCssStyles parser) captures classDef values using an unrestricted regex
    that matches everything up to a newline. That value then flows unsanitized through addStyleClass() into
    createCssStyles() and is assigned to style.innerHTML, so a closing brace (}) in the value terminates the
    generated CSS selector and turns everything after it into a new CSS rule on the page. This enables page
    defacement, user tracking via url() callbacks, and DOM attribute exfiltration. This issue has been fixed
    in versions 10.9.6 and 11.15.0. If developers are unable to immediately upgrade, they can work around this
    issue by setting "securityLevel": "sandbox", which prevents the issue by rendering the mermaid diagram in
    a sandboxed <iframe>. (CVE-2026-41148)
