GHSA-g485-8j3v-p6x8: @tdurieux/anonymous_github Vulnerable to XSS via Unsanitized GitHub Repository Content Rendering in Anonymous GitHub Origin

Anonymous GitHub fetches repository content (e.g., markdown files) from GitHub’s API and renders it without sanitization. On the client side, markdown is parsed with marked (with sanitize: false) and injected into the DOM via $sce.trustAsHtml() + ng-bind-html, bypassing AngularJS’s built-in XSS protection. An attacker can craft a malicious GitHub repository whose README executes arbitrary JavaScript in the Anonymous GitHub origin.
