CVE-2026-59511: Exclusive Addons Elementor Data Leakage Vulnerability – Patch Available

Technical summary

CVE-2026-59511 is classified as an Insertion of Sensitive Information Into Sent Data vulnerability (CWE-201), indicating the plugin inadvertently includes confidential information in outbound communications or data streams. The CVSS 3.1 score of 5.3 (MEDIUM) reflects a network-accessible flaw with low attack complexity and no privilege requirements, but limited scope and confidentiality impact. The vulnerability affects Exclusive Addons Elementor from version 2.7.9.9 and earlier. No special authentication or user interaction is required for exploitation.

Business impact

Organizations using Exclusive Addons Elementor face potential data leakage risks. Depending on what sensitive data the plugin processes—such as site metadata, user identifiers, configuration details, or form-related information—exposure could compromise customer privacy, violate compliance frameworks (GDPR, HIPAA, PCI-DSS), or provide reconnaissance data to threat actors. The risk is material but not catastrophic, as the vulnerability is read-only and does not enable account takeover, code injection, or system-level access.

Affected systems

Exclusive Addons Elementor versions up to and including 2.7.9.9 are vulnerable. The plugin runs on WordPress installations using Elementor, so any organization deploying this extension is potentially affected. Verify your current plugin version via the WordPress admin dashboard (Plugins > Installed Plugins) to confirm exposure.

Exploitability

Exploitation is straightforward: the flaw requires no authentication, user interaction, or complex attack setup. An attacker can trigger data exposure remotely by simply interacting with the affected plugin's functionality. This low barrier to exploitation, combined with the plugin's likely presence on customer-facing websites, elevates practical risk despite the moderate CVSS score. However, the vulnerability is not currently tracked as exploited in the wild (KEV status: not listed).

Remediation

Update Exclusive Addons Elementor to a version newer than 2.7.9.9 as soon as possible. Tim Strifler, the plugin developer, will have released a patched version addressing CWE-201 data leakage. Verify the availability of updates through the WordPress plugin repository or the plugin's official website before updating. Test the update in a staging environment first, especially if your site relies on the plugin's functionality in custom workflows.

Patch guidance

Access your WordPress dashboard, navigate to Plugins > Installed Plugins, and look for Exclusive Addons Elementor. If an update is available, a blue notification will appear. Click 'Update Now' or update via Plugins > Updates if you prefer a batch update. Note the current version number before updating so you can confirm the patch has been applied. After updating, clear any site caching (including CDN and browser cache) to ensure no stale plugin code is served. Monitor site functionality for 24–48 hours post-update to confirm no compatibility regressions with your Elementor pages or custom integrations.

Detection guidance

In the absence of a WAF rule specifically targeting this plugin's data leakage, detection is challenging at the network level. Focus on source-level monitoring: audit the plugin's outbound data by reviewing server access logs for unusual or verbose responses from Elementor-related requests, especially those containing user data or metadata. Consider enabling WordPress security audit logging (via plugins like Wordfence or Sucuri) to flag suspicious activity. After patching, perform a security scan of your site to ensure no residual data exposure or unauthorized access. If you operate a WAF or IDS, monitor for any CVE-2026-59511-specific signatures as they become available.

Why prioritize this

Prioritize this patch at high-urgency for any site hosting Exclusive Addons Elementor, despite the MEDIUM CVSS score. Rationale: (1) no authentication required for exploitation, (2) network-accessible from the Internet, (3) potential for compliance violation if customer or financial data is exposed, (4) low remediation effort (simple plugin update), (5) plugin prevalence in WordPress ecosystems. Delay increases dwell-time risk and potential data leakage duration.

Risk score, explained

CVSS 3.1 score of 5.3 (MEDIUM) reflects: Attack Vector (Network) = increased exploitability; Attack Complexity (Low) = straightforward to trigger; Privileges Required (None) and User Interaction (None) = no barriers; Scope (Unchanged) = impact confined to the plugin; Confidentiality Impact (Low) = data exposure limited to what the plugin processes; Integrity and Availability (None) = no modification or availability impact. The score appropriately downgrades severity because the flaw is read-only, but operational risk remains meaningful due to ease of exploitation and data sensitivity context.
