EPSS Percentile

0th

Vaultwarden is a Bitwarden-compatible server written in Rust. Prior to 1.36.0, Vaultwarden's /icons/{domain}/icon.png endpoint used src/http_client.rs checks including should_block_address() and post_resolve() that missed decimal, hexadecimal, and octal IP representations, allowing SSRF through the icon-fetching HTTP client for blind internal network or port discovery. This issue is fixed in version 1.36.0.
