CVE-2020-36760: Ocean Extra <=1.6.5 - Cross-Site Request Forgery Bypass

The Ocean Extra plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 1.6.5]. This is due to missing or incorrect nonce validation on the add_core_extensions_bundle_validation() function. This makes it possible for unauthenticated attackers to validate extension bundles via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.

Security readout for executives and security teams

Plain-English summary

This affects WordPress sites using Ocean Extra up to version 1.6.5. An attacker cannot trigger it alone; they must trick an authenticated administrator into taking an action, such as clicking a crafted link. The impact described is limited integrity change: validating extension bundles without proper CSRF protection.

Executive priority

Treat this as a moderate website administration risk. It is not described as actively exploited, but vulnerable sites could be manipulated if an administrator is socially engineered. Prioritize remediation during the next WordPress maintenance cycle, sooner for high-value or heavily administered public sites.

Technical view

CVE-2020-36760 is a CWE-352 CSRF issue in Ocean Extra’s add_core_extensions_bundle_validation() function. Missing or incorrect nonce validation allows unauthenticated attackers to cause bundle validation through a forged administrator request. CVSS 3.1 is 4.3 with required user interaction and low integrity impact.

Likely exposure

Exposure is limited to WordPress installations running the Ocean Extra plugin at versions up to and including 1.6.5. Sites without the plugin, or running versions outside the affected range, are not shown as affected by the supplied sources.

Exploitation context

The source bundle does not show CISA KEV listing or active exploitation evidence. Exploitation depends on social engineering a logged-in site administrator into performing an action. The available description does not claim remote unauthenticated exploitation without administrator interaction.

Researcher notes

The key control failure is nonce validation around add_core_extensions_bundle_validation(). Scope appears narrow: no confidentiality or availability impact is stated, and integrity impact is low. The supplied affected metadata is sparse, so rely on plugin version evidence and vendor changelog confirmation when closing findings.

Mitigation direction

  • Inventory WordPress sites for Ocean Extra and record installed versions.
  • Update Ocean Extra beyond 1.6.5 where vendor guidance confirms the fix.
  • Check Wordfence, WordPress plugin changelog, and vendor guidance for fixed-release details.
  • Limit WordPress administrator access to trusted users and managed devices.
  • Train administrators to avoid unsolicited links while logged into WordPress.

Validation and detection

  • Confirm whether Ocean Extra is installed on each WordPress site.
  • Flag any Ocean Extra version up to and including 1.6.5.
  • Review changelog or source diff for nonce validation around bundle validation.
  • Check administrative activity for unexpected extension bundle validation events.
  • Verify remediation by confirming the deployed plugin version is no longer affected.
