- Severity: CVSS 5.3 (Medium), CNA
- Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N
- CISA SSVC: exploitation=none, automatable=yes, technicalImpact=partial
- Known exploited (CISA KEV): no
- Published: 2026-02-03 · Updated: 2026-04-08

## Affected

- alimir WP ULike – Like & Dislike Buttons for Engagement and Feedback: through 4.8.3.1

## Description

The WP ULike plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 4.8.3.1. This is due to the `wp_ulike_delete_history_api` AJAX action not verifying that the log entry being deleted belongs to the current user. This makes it possible for authenticated attackers, with Subscriber-level access and above (granted the 'stats' capability is assigned to their role), to delete arbitrary log entries belonging to other users via the 'id' parameter.
