CVE-2026-15979 keywordrush CVE debrief

Who should care

WordPress site administrators using the Content Egg plugin, security teams monitoring for potential path traversal attacks, developers responsible for maintaining the plugin, and operators managing affected deployments should be aware of this vulnerability. They should assess their exposure, apply necessary patches, and monitor for suspicious activity. Additionally, vulnerability management teams and security teams should prioritize patching and review compensating controls for exposed systems. This should be done in conjunction with reviewing relevant monitoring, detection, and logs for exposed assets that need extra review, and tracking exceptions, retesting remediated assets, and closing the item only after evidence is documented. The Content Egg plugin versions up to and including 11.3.0 are affected, and immediate action is required to prevent potential remote code execution. Security teams should also verify affected scope, severity, and vendor guidance through official advisories or CVE records, and plan vendor-supported updates or mitigations through normal change control where exposure is confirmed. Affected operators and platform administrators should confirm whether affected product deployments exist in managed environments and assign an owner for follow-up. Overall, a coordinated effort is necessary to address this vulnerability effectively and minimize potential risks. The CVE record was published on 2026-08-05T14:17:03.547Z and has not been modified since then, emphasizing the need for prompt action based on the information available at that time. The vulnerability's high CVSS score of 8.1 and HIGH severity rating further underscore the urgency of this matter. Therefore, it is crucial for all relevant stakeholders to take immediate action to mitigate potential risks associated with this vulnerability. In addition to the aforementioned parties, anyone responsible for the security and integrity of WordPress sites utilizing the Content Egg plugin should also be informed and involved in the remediation process. This includes, but is not limited to, IT personnel, cybersecurity specialists, and anyone else who plays a role in ensuring the security of the

Technical summary

The Content Egg plugin for WordPress has a Path Traversal vulnerability in versions up to and including 11.3.0. The plugin does not properly validate user input in the 'img_file' field of the cegg_data post metadata. This field is only processed through wp_strip_all_tags(), which does not remove path traversal sequences. As a result, authenticated attackers with author-level access can delete arbitrary files on the server, potentially enabling remote code execution.

Defensive priority

Authenticated attackers with author-level access can delete arbitrary files, potentially enabling remote code execution.

Recommended defensive actions

• Inventory and verify Content Egg plugin version.
• Restrict access to the plugin's functionality.
• Monitor for suspicious file deletion activity.
• Implement additional security measures for file handling.
• Review compensating controls for exposed systems while remediation is scheduled and verified.
• Check relevant monitoring, detection, and logs for exposed assets that need extra review.
• Track exceptions, retest remediated assets, and close the item only after evidence is documented.

Evidence notes

The vulnerability exists in the Content Egg plugin versions up to and including 11.3.0. The 'img_file' field in cegg_data post metadata is not properly validated, allowing for path traversal attacks. The value is processed through wp_strip_all_tags(), which does not remove path traversal sequences. The file path is constructed in getFullImgPath() and passed to PHP's unlink() function.
