How to Fix CVE-2026-111874

To remediate this vulnerability, upgrade all affected Software dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

mvn dependency:tree

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2026-111874, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree

Analyze the terminal output to locate any version of Software in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than the patched release), your application is affected.

Note: The mvn dependency:tree command inspects the resolved dependency graph declared in your project's POM files; it does not perform automated security scanning or inspect runtime dynamic classpaths. Always verify runtime container classpaths and shaded JARs.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-307: Improper Restriction of Excessive Authentication Attempts, where the product does not implement sufficient measures to prevent multiple failed authentication attempts within a short time frame. In Software, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

A flaw has been found in OpenCATS 0.10.0. Affected is the function processLogin of the file modules/careers/CareersUI.php of the component Career Portal. This manipulation of the argument applyToJobSubAction causes improper restriction of excessive authentication attempts. Remote exploitation of the attack is possible. A high degree of complexity is needed for the attack. The exploitability is told to be difficult. The exploit has been published and may be used. Patch name: 1cf4fa3ee9054314b023be79d404078645c22ade. It is suggested to install a patch to address this issue. The project maintainer explains: "Candidates will now need to authenticate each time they access the Career Portal and successfully complete the CAPTCHA as part of that authentication flow. The authenticated candidate identity is now maintained server-side rather than relying on the previous persistent client-side cats…cw cookie mechanism. Application-level rate limiting is deliberately not in scope for this change. In my view, request throttling and brute-force protection of that kind are better applied at the network, reverse-proxy or web-server layer, where they can be configured appropriately for each deployment without OpenCATS having to implement and maintain its own rate-limiting framework. I'll update the online documentation to that effect."
