Sensitive information exposure via inconsistent HTTP parsing
Published Aug 12, 2026 · Updated Aug 12, 2026
Improper authentication in IBM Security Verify Access 10.0 through 10.0.9.2 lets remote attackers read sensitive data via crafted HTTP requests. The same reverse-proxy flaw affects IBM Security Verify Access Container through 10.0.9.2 and both IBM Verify Identity Access editions through 11.0.3; the proxy and downstream processor interpret one request inconsistently. No credentials or user interaction are required, but exploitation has high complexity; IBM has not disclosed the conflicting HTTP elements or a safe behavioral test.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=10.0 <=10.0.9.2
