CVE-2026-28675Network attack vector

Information disclosure via raw errors and token responses

Published Mar 6, 2026 · Updated Mar 6, 2026

Information disclosure in OpenSift before 1.6.3-alpha allows remote attackers to obtain exception details and login token material. The sift_generate handler returned str(e) from provider failures, while UI templates and the token-rotation response exposed the full login token. No privileges or user interaction are required; the disclosed data supports reconnaissance and attack chaining, with no reported integrity or availability impact.
