Astro full-read SSRF: Host validation and prerendered error-page fetching
Astro Full-Read SSRF via Host Header Injection
AI-collected research leads through 22 September 2026, including targeted additions between broader sweeps. Unranked, incomplete, not community-vetted, and subject to change.
Traces a full-read SSRF through Astro’s server-side fetching of prerendered custom error pages. Host-derived URLs and uneven validation of Host and forwarded-host headers expose internal responses in a particular hybrid rendering configuration. The article supplies setup and debugging details for this overlooked self-fetch boundary.
