CVE-2025-22657: Atarim Auth Bypass Vulnerability

CVE-2025-22657 Overview

CVE-2025-22657 is a missing authorization vulnerability in the Vito Peleg Atarim Visual Collaboration plugin for WordPress. The flaw affects all versions up to and including 4.0.9. Attackers can exploit incorrectly configured access control security levels to delete arbitrary content on affected sites. The vulnerability is exploitable over the network without authentication or user interaction. The weakness is classified under [CWE-862: Missing Authorization].

Critical Impact

Unauthenticated remote attackers can trigger arbitrary content deletion on WordPress sites running vulnerable versions of the Atarim plugin, resulting in loss of availability.

Affected Products

• Vito Peleg Atarim Visual Collaboration plugin for WordPress
• All versions through 4.0.9
• WordPress sites with the atarim-visual-collaboration plugin enabled

Technical Details for CVE-2025-22657

Vulnerability Analysis

The Atarim Visual Collaboration plugin provides client feedback and visual collaboration features for WordPress sites. The plugin exposes functionality that performs content deletion operations without enforcing proper authorization checks. An unauthenticated attacker can invoke these endpoints over the network and trigger destructive actions against site content.

The vulnerability produces an availability impact because attackers can remove site content. Confidentiality and integrity are not directly affected by the flaw, but the loss of stored content can disrupt operational continuity for affected sites. The EPSS probability is 0.173% with a percentile of 38.204.

Root Cause

The root cause is missing authorization on plugin endpoints that perform content modification. The plugin does not verify whether the requesting user holds the required capability or role before executing the destructive operation. This pattern matches [CWE-862], where access control checks are absent from a sensitive code path. Combined with the lack of authentication requirements, any remote actor can reach the vulnerable handler.

Attack Vector

Attackers send crafted HTTP requests to the vulnerable plugin endpoint exposed by WordPress. Because no privileges or user interaction are required, automated scanning tools can locate and exploit affected installations at scale. Refer to the Patchstack Vulnerability Report for additional technical context on the affected endpoint behavior.

Detection Methods for CVE-2025-22657

Indicators of Compromise

• Unexpected deletion of posts, pages, or media items on WordPress installations running the Atarim plugin
• HTTP requests to atarim-visual-collaboration plugin endpoints from unauthenticated sources
• WordPress audit log entries showing content removal actions without an associated authenticated user session

Detection Strategies

• Inventory all WordPress sites and identify installations running the Atarim Visual Collaboration plugin at version 4.0.9 or earlier
• Monitor web server access logs for anomalous POST requests targeting plugin AJAX or REST endpoints
• Correlate WordPress database write events with authenticated session data to flag unauthorized deletions

Monitoring Recommendations

• Enable WordPress activity logging plugins to capture content lifecycle events with originating IP addresses
• Forward web server and WordPress logs to a centralized logging platform for correlation and alerting
• Configure alerts for bulk content deletion events occurring within short time windows

How to Mitigate CVE-2025-22657

Immediate Actions Required

• Identify and inventory all WordPress sites running the Atarim Visual Collaboration plugin
• Update the plugin to a version higher than 4.0.9 once a fixed release is available from the vendor
• Restrict network access to WordPress administrative and plugin endpoints using a web application firewall
• Take recent backups of WordPress databases and uploads to support recovery from unauthorized deletions

Patch Information

The vulnerability affects Atarim Visual Collaboration versions through 4.0.9. Site administrators should consult the Patchstack Vulnerability Report and the WordPress plugin repository for the latest fixed release. Apply the update across all affected sites and verify the plugin version after deployment.

Workarounds

• Deactivate and remove the Atarim Visual Collaboration plugin until a patched version is installed
• Deploy a web application firewall rule blocking unauthenticated requests to plugin endpoints under /wp-admin/admin-ajax.php and /wp-json/ paths used by the plugin
• Restrict plugin endpoint access to known IP ranges via server-level configuration where collaboration is limited to specific reviewers
