Technical Details for CVE-2026-59511

Vulnerability Analysis

The vulnerability stems from improper handling of sensitive information within data that the plugin sends to clients. The Exclusive Addons for Elementor plugin embeds data into rendered output or plugin responses that should not be exposed to unauthenticated users. Because the exposure occurs in outbound data flows, attackers do not need authentication, elevated privileges, or user interaction to retrieve the information. The scope of impact is limited to confidentiality, with no direct effect on data integrity or site availability. The Exploit Prediction Scoring System places the probability of near-term exploitation at 0.201% as of July 9, 2026.

Root Cause

The root cause is classified as [CWE-201: Insertion of Sensitive Information Into Sent Data]. The plugin includes sensitive fields or metadata in HTTP responses or rendered widget output without filtering them based on the requester's authentication state or capability. This design flaw exposes information that should be restricted to administrators or authenticated users.

Attack Vector

The attack vector is Network. An attacker sends crafted HTTP requests to a WordPress site hosting the vulnerable plugin and parses the responses for embedded sensitive data. No credentials or user interaction are required. Because the plugin serves data through standard WordPress endpoints, exploitation is trivial to automate across large numbers of exposed sites.

No public proof-of-concept code has been released for CVE-2026-59511. See the Patchstack Vulnerability Report for the authoritative technical description.

Detection Methods for CVE-2026-59511

Indicators of Compromise

Repeated unauthenticated HTTP GET requests to pages rendering Exclusive Addons widgets from a small set of source IP addresses
Anomalous scraping patterns targeting /wp-content/plugins/exclusive-addons-for-elementor/ asset paths or REST endpoints
Unexpected inclusion of internal identifiers, user metadata, or configuration values in publicly served page markup

Detection Strategies

Inspect HTTP responses from Elementor-rendered pages for fields not intended for public exposure, such as user identifiers, private post metadata, or plugin configuration values
Correlate web server access logs with WordPress plugin inventory data to flag hosts running Exclusive Addons for Elementor at or below version 2.7.9.9
Deploy WordPress plugin vulnerability scanners that consume the Patchstack advisory feed for CVE-2026-59511

Monitoring Recommendations

Enable verbose access logging on WordPress front-end and REST API endpoints and retain logs for at least 90 days
Alert on high-volume unauthenticated requests to pages containing Exclusive Addons shortcodes or widgets
Track plugin version numbers across the WordPress fleet and generate alerts when hosts remain on 2.7.9.9 or earlier

How to Mitigate CVE-2026-59511

Immediate Actions Required

Inventory all WordPress installations to identify sites running Exclusive Addons for Elementor version 2.7.9.9 or earlier
Update the plugin to a version above 2.7.9.9 once the vendor publishes a fixed release
Restrict access to affected sites via a web application firewall rule blocking unauthenticated scraping of widget endpoints until patching is complete
Review recent web server logs for signs of bulk enumeration against Elementor-rendered pages

Patch Information

The Patchstack advisory tracks affected versions from an unspecified initial release through 2.7.9.9. Refer to the Patchstack Vulnerability Report for the current fixed version and vendor guidance.

Workarounds

Disable the Exclusive Addons for Elementor plugin on affected sites until an updated version is installed
Deploy WAF rules that strip or block sensitive fields in responses served by vulnerable widget endpoints
Limit anonymous access to pages that embed Exclusive Addons widgets by placing them behind authentication where feasible

bash

# Configuration example
# Identify WordPress sites running the vulnerable plugin version
wp plugin list --format=csv | grep 'exclusive-addons-for-elementor'

# Deactivate the plugin as a temporary mitigation
wp plugin deactivate exclusive-addons-for-elementor
