Mozilla security engineer Frederik Braun reported an issue where the implementation of Content Security Policy (CSP) is not in compliance with the specification. XSLT stylesheets must be subject to script-src directives but Mozilla’s implementation of CSP treats them as styles. This could lead to unexpected script execution if the style-src directives were less restrictive than those for scripts.
