CVE-2026-54722

DSSRF (Node.js library) has a vulnerability in is_url_safe prior to version 1.0.4. The bug arises because is_url_safe strips the @ userinfo delimiter via remove_at_symbol_in_string before parsing URLs, allowing an attacker-controlled URL to bypass internal-IP validation and cause a client using t...

GHSA-CG4G-M8JX-VJV2 dssrf has an SSRF bypass with remove_at_symbol_in_string

Summary isurlsafe in v1.0.3 contains an SSRF bypass. removeatsymbolinstring is applied to the raw URL string before new URL parses it. This strips the @ that separates userinfo from host, corrupting the hostname so internal IPs are never checked. Vulnerability In helpers.ts, isurlsafe does: ts u ...
