CVE-2026-19543

An attacker can modify requests to bypass validation controls and submit unauthorized values, potentially resulting in unintended application behavior.

MEDIUM 6.2EPSS 0.17%

Does this matter?

Lower severity and a low EPSS score (0.17%). Track it; it rarely justifies an emergency change on its own.

Description

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.
