How to Fix CVE-2025-13609

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

keylime fixed: 7.13.0 
pip install keylime>=7.13.0
Verify Direct and Transitive Dependencies

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

pip show keylime

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2025-13609, inspect your installed packages using pip:

pip show keylime

Analyze the terminal output to locate any version of Keylime in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 7.13.0), your application is affected.

Note: The pip show keylime command checks currently installed packages in your active Python environment.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-694: Use of Multiple Resources with Duplicate Identifier, where the product uses multiple resources that can have the same identifier, in a context in which unique identifiers are required. In Keylime, 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 vulnerability has been identified in keylime where an attacker can exploit this flaw by registering a new agent using a different Trusted Platform Module (TPM) device but claiming an existing agent's unique identifier (UUID). This action overwrites the legitimate agent's identity, enabling the attacker to impersonate the compromised agent and potentially bypass security controls.
