CVE-2021-24379: Comments Like Dislike < 1.1.4 - Add Like/Dislike Bypass

The Comments Like Dislike WordPress plugin before 1.1.4 allows users to like/dislike posted comments, however does not prevent them from replaying the AJAX request to add a like. This allows any user (even unauthenticated) to add unlimited like/dislike to any comment. The plugin appears to have some Restriction modes, such as Cookie Restriction, IP Restrictions, Logged In User Restriction, however, they do not prevent such attack as they only check client side

Security readout for executives and security teams

Plain-English summary

CVE-2021-24379 lets anyone inflate likes or dislikes on comments in the Comments Like Dislike WordPress plugin. The impact is content and reputation manipulation, not evidence of server takeover or data theft. Public sites using affected plugin versions should treat it as a trust and moderation issue.

Executive priority

Prioritize remediation on public WordPress sites where comment reactions affect customer trust, ratings, campaigns, or moderation decisions. This is not presented as a data breach issue, but it can undermine content integrity and brand credibility.

Technical view

The plugin before 1.1.4 failed to prevent replay of its AJAX like/dislike request. Existing restriction modes were described as client-side checks, so unauthenticated users could repeatedly add reactions to any comment. The assigned weakness is CWE-863, indicating improper authorization.

Likely exposure

Exposure is limited to WordPress sites running Comments Like Dislike versions before 1.1.4, especially where public comments are enabled. Evidence in the bundle is sparse and version metadata is inconsistent, but the title and description identify versions before 1.1.4.

Exploitation context

The source bundle does not show CISA KEV listing or active exploitation evidence. The vulnerability is easy to understand conceptually because it involves replaying a public AJAX action, but no exploit code or weaponization details are provided here.

Researcher notes

Key uncertainty is source completeness: no CVSS score, no detailed vendor advisory, and no KEV evidence are included. The core issue is authorization bypass through replayable AJAX state changes, with unauthenticated impact stated in the CVE description.

Mitigation direction

  • Upgrade Comments Like Dislike to version 1.1.4 or later where available.
  • Check WPScan and vendor guidance for any additional recommended actions.
  • Disable the plugin if an update is unavailable or business impact is unacceptable.
  • Review comment reaction counts for suspicious manipulation after remediation.

Validation and detection

  • Inventory WordPress sites for the Comments Like Dislike plugin and installed version.
  • Confirm public comment reaction features are not running an affected version.
  • Review plugin settings, but do not rely on client-side restriction modes alone.
  • Check moderation logs or analytics for abnormal like/dislike spikes.

Incorrect Authorization

Incorrect Authorization represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
