CVE-2026-1264
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedIBM Sterling B2B Integrator and IBM Sterling File Gateway 6.1.0.0 through 6.1.2.7_2, 6.2.0.0 through 6.2.0.5_1, 6.2.1.0 through 6.2.1.1_1, and 6.2.2.0 allows a remote unauthenticated attacker to view and delete the partners of a community and to delete the communities.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceIBM Sterling B2B Integrator and Sterling File Gateway contain an improper access control vulnerability in their community/partner management functionality. A remote unauthenticated attacker can access API endpoints or interfaces that should require authentication, allowing them to view partner information and delete both partners and entire communities.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify installed IBM Sterling product and versionCheck the product version through the admin console or by inspecting the installation directory for version files. Common locations include the installation properties file or the admin UI dashboard that displays the running version.Affected if The installed version falls within the affected ranges: 6.1.0.0 through 6.1.2.7, 6.2.0.0 through 6.2.0.5_1, 6.2.1.0 through 6.2.1.1_1, or exactly 6.2.2.0.
-
Determine if community/partner management interface is exposedReview network accessibility of the web-based admin console and partner management portals. Check if these interfaces are listening on external network interfaces or behind proper authentication gates.Affected if The partner management or community management interfaces are reachable from untrusted networks without requiring authentication.
-
Check API endpoint accessibility without authenticationAttempt to access common partner management API endpoints (such as those handling partner or community CRUD operations) without providing credentials. Inspect access logs for unauthorized access patterns to these endpoints.Affected if API endpoints related to partner or community management respond successfully to unauthenticated requests, allowing viewing or modification of partner data.
-
Review access control configuration for partner managementInspect the access control settings within the Sterling admin console or configuration files to verify that partner/community management functions require authentication.Affected if Access controls are misconfigured or missing for the community/partner management functionality, permitting unauthenticated access.
Your environment is affected if you are running an affected version of IBM Sterling B2B Integrator or Sterling File Gateway and the community/partner management interface or its API endpoints are accessible without authentication.
