CVE-2026-100180 jegtheme CVE debrief

Who should care

Defenders responsible for WordPress installations with the Jeg Kit for Elementor plugin should assess exposure and prioritize verification of the presence of this vulnerability, particularly for unauthenticated comment submission functionality.

Why it matters

Defenders should prioritize verifying the presence of this vulnerability in their WordPress installations and assess exposure, particularly for unauthenticated comment submission functionality, as it allows unauthenticated attackers to inject arbitrary web scripts.

• Unauthenticated attackers can inject arbitrary web scripts in pages
• Injected scripts execute whenever a user accesses an injected page
• Immediate persistence without moderator approval is possible when the attacker submits from an email address with at least one previously approved comment
• Verification of input sanitization and output escaping implementation is required

Technical summary

The Jeg Kit for Elementor plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Comment in all versions up to, and including, 3.2.19. This is due to insufficient input sanitization and output escaping, allowing unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. Defenders should prioritize verifying the presence of this vulnerability in their WordPress installations and assess exposure, particularly for unauthenticated comment submission functionality. Immediate persistence without moderator approval is possible when the attacker submits from an email address with at least one previously approved comment.

Defensive priority

Defenders should prioritize verifying the presence of this vulnerability in their WordPress installations and assess exposure, particularly for unauthenticated comment submission functionality.

Recommended defensive actions

• Assess exposure to unauthenticated comment submission functionality
• Implement input sanitization and output escaping for comment functionality
• Monitor for suspicious activity related to comment injection
• 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
