Content Egg - Remote Code Execution (CVE-2026-15979)
CVE-2026-15979
The Content Egg – Affiliate Product Importer & Price Comparison plugin for WordPress is vulnerable to Arbitrary File Deletion via Path Traversal in versions up to and including 11.3.0. This is due to insufficient validation of the 'img_file' field within the cegg_data post metadata: the value passes only through wp_strip_all_tags() (which does not strip path traversal sequences), is stored directly in post meta, and is later concatenated without normalization into a filesystem path in getFullImgPath() before being passed to PHP's unlink(). This makes it possible for authenticated attackers, with author-level access and above, to delete arbitrary files on the affected site's server which may make remote code execution possible.

Potential Impact
Severity is HIGH (CVSS 8.1). Depending on deployment context, affected components may be exposed to unauthorized actions or data integrity risk.
Exploitability Assessment
Exploitability is assessed as High based on remote code execution potential.
Primary risk drivers: remote code execution potential
Mitigation Recommendations
Validate affected product versions, prioritize patching, and monitor references for vendor remediation guidance. If immediate patching is not possible, apply compensating controls and limit exposure of vulnerable surfaces.
Detection & Monitoring
Track authentication anomalies, unexpected file writes, and suspicious plugin API activity around affected components.
Business Impact Lens
AI risk score 81/100 (High, High) with priority P2 Urgent. Prioritize remediation where affected components process customer data, admin sessions, or Internet-exposed workflows.
