CVE-2026-47160

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.

Summary		(es) Vaultwarden es un servidor compatible con Bitwarden escrito en Rust. Antes de la versión 1.36.0, el endpoint /icons/{domain}/icon.png de Vaultwarden utilizaba comprobaciones de src/http_client.rs, incluyendo should_block_address() y post_resolve(), que pasaban por alto representaciones IP decimales, hexadecimales y octales, lo que permitía SSRF a través del cliente HTTP de obtención de iconos para el descubrimiento ciego de redes internas o puertos. Este problema está solucionado en la versión 1.36.0.
