How to fix?

Upgrade RHEL:7 eap7-undertow to version 0:2.0.41-8.SP9_redhat_00001.1.el7eap or higher.
This issue was patched in RHSA-2026:33371.

NVD Description

Note: Versions mentioned in the description apply only to the upstream eap7-undertow package and not the eap7-undertow package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

The _.unset and _.omit functions in Lodash are vulnerable to prototype pollution. An attacker can pass crafted paths which cause Lodash to delete methods from global prototypes. The issue permits deletion of properties but does not allow overwriting their original behavior. The issue is patched from 4.17.23 to 4.18.0 depending on the package: lodash, lodash-es, and lodash-amd in 4.17.23, and the standalone lodash.unset and lodash.omit packages in 4.18.0.
