SCA: security update for mermaid (GHSA-ghcm-xqfw-q4vr)
medium Tenable Self-Hosted Container Security Plugin ID 441751
Description
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 earlier, as well as 11.0.0-alpha.1 through 11.14.0, are vulnerable to HTML injection
under the default configuration. Specifically, the classDef directive in Mermaid state diagrams permits
DOM injection that escapes the SVG context. However, <script> tags are stripped, which prevents cross-site
scripting (XSS). 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-2026-41149)
Solution
Update the mermaid library and its related packages to version 10.9.6 or later.See Also
