Content Egg - Security Vulnerability (CVE-2026-119059)
CVE-2026-119059
The Content Egg plugin for WordPress is vulnerable to unauthorized modification of data due to a missing per-post capability check on the ajaxUpdateProducts() function in versions up to, and including, 12.0.0. The handler verifies a static nonce ('contentegg_metabox') and the generic 'edit_posts' capability, but trusts the attacker-supplied $_POST['post_id'] verbatim and never calls current_user_can('edit_post', $post_id) — the per-object check that its sibling save_post handler saveMeta() correctly performs. This makes it possible for authenticated attackers, with contributor-level access and above, to modify Content Egg product data (_cegg_data_*) and update-timestamp post meta on arbitrary posts, including those owned by administrators.

Potential Impact
Severity is MEDIUM (CVSS 4.3). 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 46/100 (Moderate, High) with priority P4 Planned. Prioritize remediation where affected components process customer data, admin sessions, or Internet-exposed workflows.
