How to Fix CVE-2025-60868

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

alt-design/alt-redirect fixed: 1.6.4 
Upgrade alt-design/alt-redirect to 1.6.4
Verify Direct and Transitive Dependencies

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

inspect dependencies for alt-design/alt-redirect

How to Check if You Are Affected

To determine whether your application is affected by CVE-2025-60868, inspect your project dependencies for Alt Redirect:

inspect dependencies for alt-design/alt-redirect

Analyze the terminal output to locate any version of Alt Redirect in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.6.4), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-290: Authentication Bypass by Spoofing, where this attack-focused weakness is caused by incorrectly implemented authentication schemes that are subject to spoofing attacks. In Alt Redirect, 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

The Alt Redirect 1.6.3 addon for Statamic fails to consistently strip query string parameters when the "Query String Strip" feature is enabled. Case variations, encoded keys, and duplicates are not removed, allowing attackers to bypass sanitization. This may lead to cache poisoning, parameter pollution, or denial of service.
