CVE-2026-15322Network attack vector

Session-token disclosure via URL query strings

Published Jul 17, 2026 · Updated Jul 17, 2026

Information disclosure in IBM Engineering AI Hub 1.0.0 through 1.2.0 allows remote attackers to obtain session tokens from URLs. The application places session tokens in URL query strings, where browser history, referrer data, intermediary records, and web logs can retain them. Network access requires no authentication or user interaction; the reported impact is limited to session-token confidentiality, with no data modification or service interruption.
