Description

Astro-Shield is an integration to enhance website security with SubResource Integrity hashes, Content-Security-Policy headers, and other techniques. Versions from 1.2.0 to 1.3.1 of Astro-Shield allow bypass to the allow-lists for cross-origin resources by introducing valid `integrity` attributes to the injected code. This implies that the injected SRI hash would be added to the generated CSP header, which would lead the browser to believe that the injected resource is legit. This vulnerability is patched in version 1.3.2.
