CVE-2026-33242 is a high-severity Path Traversal and Access Control Bypass vulnerability affecting Salvo Rust web framework versions 0.39.0 through 0.89.2, specifically within its salvo-proxy component. Rated with a CVSS score of 7.5, this flaw allows an unauthenticated attacker to bypass proxy routing constraints and access sensitive backend paths, such as administrative dashboards, due to improper URL path normalization. The attack vector is network-based with low complexity, posing a high confidentiality risk. There is currently no evidence of active exploitation, nor are public exploit modules available in Metasploit, Nuclei, or ExploitDB, and community discussion remains minimal. Organizations using affected versions should upgrade to Salvo 0.89.3 or newer to remediate this vulnerability.
