How to Fix CVE-2026-67602

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-2026-67602, 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-706: Use of Incorrectly-Resolved Name or Reference, where the product uses a name or reference to access a resource, but the name/reference resolves to a resource that is outside of the intended control sphere. 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

phpIPAM before 1.8.2 contains an authentication bypass vulnerability in the REST API that allows unauthenticated attackers to gain full API access by exploiting an insecure object cache keying mechanism. The cache is keyed by lookup value alone without including the searched column, enabling an entry written during an app_id lookup to satisfy a subsequent app_code lookup, allowing attackers to use the numeric database row identifier as an API token to read, write, and delete all IP address management records.
