Real-World Exposure
alt-design/alt-redirectReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects Packagist packages — download data is not available via public APIs for these ecosystems.
Description
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.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for alt-design/alt-redirect, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update alt-design/alt-redirect to 1.6.4 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2025-60868 is resolved across your whole dependency graph.
Workarounds
Cap what an attacker can consume: apply request size, rate and timeout limits in front of the affected component, and run it with memory and CPU limits so exhaustion degrades one worker rather than the whole service.
