Upload Quota per User can let attackers run code

CVE-2025-30537 · published 1 year ago
Summary

The Upload Quota per User component (versions up to 1.3) does not properly clean user-supplied data, allowing a malicious script to be saved and later displayed to other users. This could let an attacker steal information or perform actions on behalf of a logged‑in user. Update to the latest version or remove the plugin until a fix is applied, and ensure any custom input handling validates and encodes data before display.
