CVE-2025-64525
Good to know:
Date: November 13, 2025
Astro is a web framework. In Astro versions 2.16.0 up to but excluding 5.15.5 which utilizeon-demand rendering, request headers "x-forwarded-proto" and "x-forwarded-port" are insecurely used, without sanitization, to build the URL. This has several consequences, the most important of which are: middleware-based protected route bypass (only via "x-forwarded-proto"), DoS via cache poisoning (if a CDN is present), SSRF (only via "x-forwarded-proto"), URL pollution (potential SXSS, if a CDN is present), and WAF bypass. Version 5.15.5 contains a patch.
