Sensitive user data disclosure via expired tokens

Published Mar 13, 2026 · Updated Mar 13, 2026

IBM Sterling Partner Engagement Manager accepts expired access tokens, allowing remote attackers to read sensitive user information. The access-token validation path treats a token as usable after expiration and authorizes requests that expose user data. No current account or user interaction is required, but remote attackers must possess an expired token; IBM has not disclosed the specific endpoints or data fields.
