CVE-2025-8778Network attack vector

Compression setting modification via missing capability check

Published Sep 10, 2025 · Updated Apr 8, 2026

Missing authorization in NitroPack 1.18.4 and earlier allows remote authenticated users to change the plugin's compression setting. The nitropack_set_compression_ajax function accepts an AJAX request and updates nitropack-enableCompression without checking the caller's capability. Subscriber-level access is sufficient; the bounded impact is unauthorized modification of the site's compression configuration.
