CVE-2026-4361 Elegant Themes CVE debrief

The Divi theme for WordPress is vulnerable to Server-Side Request Forgery (SSRF) in all versions up to, and including, 4.27.6. This vulnerability allows authenticated attackers with Contributor-level access and above to make web requests to arbitrary locations originating from the web application server. Although the response body is not returned to the attacker (blind SSRF), two oracles exist: a status oracle and a timing oracle. The status oracle allows attackers to determine if a target responded with HTTP 200 based on the returned URL string. The timing oracle reveals target reachability based on response time variations.

Who should care

Defenders responsible for WordPress installations using the Divi theme, particularly those with Contributor-level access and above, should assess exposure and prioritize remediation. Security teams and administrators should review access controls, user role permissions, and implement compensating controls to prevent potential attacks.

Why it matters

The Divi theme for WordPress SSRF vulnerability allows authenticated attackers to make web requests to arbitrary locations, potentially leading to security breaches. Defenders should prioritize remediation and implement compensating controls to prevent exploitation.

  • Verify and update Divi theme versions to prevent exploitation
  • Review access controls and user role permissions to prevent unauthorized access
  • Monitor for unusual web request patterns to detect potential attacks
  • Implement compensating controls like web application firewalls (WAFs) to prevent exploitation

Technical summary

The Divi theme for WordPress is vulnerable to Server-Side Request Forgery (SSRF) in all versions up to, and including, 4.27.6. The `et_pb_set_video_oembed_thumbnail_resolution()` function uses `wp_remote_get()` instead of `wp_safe_remote_get()` to fetch a remote image URL, which does not restrict requests to private or reserved IP ranges. This allows authenticated attackers with Contributor-level access and above to make web requests to arbitrary locations originating from the web application server.

Defensive priority

Defenders should prioritize verifying and updating Divi theme versions to prevent exploitation. Contributor-level access and above are required for exploitation, so access controls and user role permissions should be reviewed. Monitoring for unusual web request patterns and implementing compensating controls like web application firewalls (WAFs) can help detect and prevent potential attacks.

Recommended defensive actions

  • Verify and update Divi theme versions to prevent exploitation
  • Review access controls and user role permissions
  • Monitor for unusual web request patterns
  • Implement compensating controls like web application firewalls (WAFs)
  • Perform vulnerability scanning to identify exposed assets
  • Review and update asset inventory to ensure accurate tracking
  • Track remediation progress and verify successful mitigation
