IBM Common Licensing: improper input validation
Medium6.2CVE-2026-19543 · Published Sep 14, 2026 · updated Sep 16, 2026
IBM Common Licensing Agent 9.0, Agent 9.0.0.1, Agent 9.0.0.2, ART 9.0, ART 9.0.0.1, and ART 9.0.0.2 performs input validation exclusively on the client side and fails to enforce the same restrictions on the server side. An attacker can modify requests to bypass validation controls and submit unauthorized values, potentially resulting in unintended application behavior.
