## What is CVE-2026-47160?

CVE-2026-47160 is a medium-severity server-side request forgery vulnerability in dani-garcia vaultwarden, published on 15 Jul 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

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.

Weakness: CWE-918 (Server-Side Request Forgery), CWE-1389 (Incorrect Parsing of Numbers with Different Radices)
