CVE-2026-33682 is an unauthenticated Server-Side Request Forgery (SSRF) vulnerability affecting Streamlit Open Source versions prior to 1.54.0 when running on Windows hosts. This flaw arises from improper validation of attacker-supplied filesystem paths, specifically malicious UNC paths, which can cause the Streamlit server to initiate outbound SMB connections. With an adjacent attack vector and high attack complexity (CVSS 4.7 Medium), successful exploitation can lead to NTLM relay attacks against internal services or the identification of internal SMB hosts. There is currently no evidence of active exploitation, nor are public exploit codes or significant community discussion available for this vulnerability.
