SCA: security update for @nuxtjs/mdc (GHSA-j82m-pc2v-2484)
critical Tenable Self-Hosted Container Security Plugin ID 420838
Description
There are packages installed that are affected by a vulnerability referenced in the following CVE:- MDC is a tool to take regular Markdown and write documents interacting deeply with a Vue component. In
affected versions unsafe parsing logic of the URL from markdown can lead to arbitrary JavaScript code due
to a bypass to the existing guards around the `javascript:` protocol scheme in the URL. The parsing logic
implement in `props.ts` maintains a deny-list approach to filtering potential malicious payload. It does
so by matching protocol schemes like `javascript:` and others. These security guards can be bypassed by an
adversarial that provides JavaScript URLs with HTML entities encoded via hex string. Users who consume
this library and perform markdown parsing from unvalidated sources could result in rendering vulnerable
XSS anchor links. This vulnerability has been addressed in version 0.13.3 and all users are advised to
upgrade. There are no known workarounds for this vulnerability. (CVE-2025-24981)
