NVD description

Salvo is a Rust web framework. Versions 0.39.0 through 0.89.2 have a Path Traversal and Access Control Bypass vulnerability in the salvo-proxy component. The vulnerability allows an unauthenticated external attacker to bypass proxy routing constraints and access unintended backend paths (e.g., protected endpoints or administrative dashboards). This issue stems from the encode_url_path function, which fails to normalize "../" sequences and inadvertently forwards them verbatim to the upstream server by not re-encoding the "." character. Version 0.89.3 contains a patch.

Patch
I have identified a Path Traversal and Access Control Bypass vulnerability in the Salvo Rust framework, now officially tracked as CVE-2026-33242. The vulnerability exists in the salvo-proxy component due to improper URL path normalization in the encode_url_path function. This allows unauthenticated attackers to bypass gateway routing constraints and access protected backend endpoints via dot-sequence payloads. The issue has been patched in Salvo v0.89.3. 🔗Technical Advisory: https://github.com/salvo-rs/salvo/security/advisories/GHSA-f842-phm9-p4v4 #RustLang #CVE #VulnerabilityResearch
