CVSS measures technical severity, not the likelihood of an attack.

Known exploitation

Not listed in the checked CISA KEV catalog

Absence from CISA KEV does not rule out attacks.

Missing evidence does not mean no public exploit exists.

Remediation

Source guidance available

Review the recorded instructions. Guidance may be a workaround rather than a fixed version.

What this means

Hibernate Validator versions 5.4.1.Final to 9.1.4.Final are affected by an expression language injection vulnerability, which could allow a remote attacker to cause a denial of service due to uncontrolled resource consumption. The vulnerability is caused by improper escaping of user-controlled data in Expression Language (EL) expressions. Affected versions include 5.4.1.Final to 6.2.5.Final, 7.0.0.Alpha1 to 7.0.5.Final, 8.0.0.Alpha1 to 8.0.5.Final, 9.0.0.Beta2 to 9.0.1.Final, and 9.1.0.Alpha1 to 9.1.4.Final.

Summarized by @cf/meta/llama-3.3-70b-instruct-fp8-fast. Verify details against the original sources.

What to do

Compare your installed product and version with the affected versions above. A matching product name alone does not confirm exposure.

It is strongly recommended to address the vulnerability by upgrading to the latest version.

Upgrade to 6.2.6.Final, 7.0.6.Final, 8.0.6.Final, 9.0.2.Final, 9.1.5.Final or later.

ibm guidance ↗

The safe alternative for custom validators is to use addExpressionVariable instead of addMessageParameter when injecting user-controlled values into EL-enabled messages, as expression variables are bound as typed objects and are never re-parsed as EL expressions.
