Unauthorized auction and content deletion in Ultimate WordPress Auction Plugin

IdentifiersCVE-2025-0958CWE-862

The Ultimate WordPress Auction Plugin for WordPress is vulnerable to unauthorized access to functionality in all versions up to and including 4.2.9. According to the provided description, the plugin fails to properly restrict access to privileged auction-handling functionality, allowing authenticated users with Contributor-level access or higher to invoke actions they should not be permitted to perform. As a result, such users can delete arbitrary auctions, posts, and pages, and perform other auction-related actions outside their intended authorization level.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation allows an authenticated low-privileged user, starting at the Contributor role, to perform unauthorized destructive and administrative actions within the affected WordPress site. This includes deletion of arbitrary auctions, posts, and pages, resulting in integrity loss and potential business disruption for sites relying on the plugin for auction operations. Depending on what additional auction-handling actions are exposed, exploitation may also permit broader unauthorized modification of auction-related data and workflows.

Mitigation

If you can’t patch tonight, do this now.

Until a fixed version is deployed, restrict or remove Contributor-level and other non-essential authenticated access to sites using the plugin, especially for users who do not require auction-related capabilities. Disable the plugin if operationally feasible. Increase monitoring and logging for deletion events affecting auctions, posts, and pages, and review plugin-exposed actions for abuse by lower-privileged users. Applying least-privilege role assignments and limiting account creation can reduce exposure.

Remediation

Patch, then assume compromise.

Update the Ultimate WordPress Auction Plugin to a version newer than 4.2.9 once a vendor fix is available. Review the plugin's authorization checks to ensure all auction-management and content-deletion actions enforce appropriate capability validation on the server side. After patching, audit site content and auction records for unauthorized deletions or modifications performed by Contributor-level or other non-administrative accounts.
