CVE-2026-1264Network attack vector

Partner disclosure and deletion via missing authentication

Published Mar 17, 2026 · Updated Mar 17, 2026

Missing authentication in the AFT web app in affected IBM Sterling B2B Integrator 6.1 and 6.2 releases allows remote attackers to alter community data. The app accepts requests to view or delete a community's partners and to delete communities without enforcing authentication for those critical operations. Network reachability of the AFT web app is required; successful access exposes partner records and permits destructive changes, although IBM's published CVSS vector marks low privileges as required.
