CVE-2026-61976 Overview
CVE-2026-61976 is a sensitive information disclosure vulnerability in the Crocoblock JetBlocks For Elementor WordPress plugin. The flaw affects all versions up to and including 1.5.0. It is categorized under [CWE-497]: Exposure of Sensitive System Information to an Unauthorized Control Sphere. An unauthenticated remote attacker can retrieve embedded sensitive data from the plugin over the network without user interaction. The issue does not directly compromise integrity or availability but enables reconnaissance that can support follow-on attacks against the target WordPress site.
Critical Impact
Unauthenticated attackers can retrieve embedded sensitive data from vulnerable JetBlocks For Elementor installations, aiding reconnaissance and enabling follow-on exploitation.
Affected Products
- Crocoblock JetBlocks For Elementor (jet-blocks) — versions from n/a through 1.5.0
- WordPress sites running the plugin with default configuration
- Elementor-based sites that install JetBlocks as a page-building extension

Technical Details for CVE-2026-61976
Vulnerability Analysis
The vulnerability allows an unauthenticated remote actor to access sensitive system information embedded within the JetBlocks For Elementor plugin. The flaw is exploitable over the network with low attack complexity and requires no privileges or user interaction. Impact is limited to confidentiality; no direct integrity or availability effects are reported. The current EPSS probability is 0.197%, indicating a low near-term likelihood of widespread exploitation, though the low barrier to abuse makes opportunistic scanning plausible.
Root Cause
The root cause is improper containment of sensitive system data within a component reachable by unauthorized parties, aligning with [CWE-497]. The plugin exposes information that should be restricted to authenticated administrators or kept server-side only. Because the exposure occurs through a network-accessible interface without authentication controls, any anonymous requester can retrieve it. See the Patchstack Vulnerability Report for advisory details.
Attack Vector
An attacker sends unauthenticated HTTP requests to the WordPress instance to interact with the exposed plugin endpoint or asset. The server returns embedded sensitive data that the attacker can parse and use for reconnaissance. The disclosed information can inform targeted follow-on attacks against WordPress, the underlying host, or other installed plugins. Full technical mechanics are described in the vendor and third-party advisories.
No verified public proof-of-concept code is available. See the Patchstack Vulnerability Report for further technical context.
Detection Methods for CVE-2026-61976
Indicators of Compromise
- Unauthenticated HTTP GET requests to JetBlocks plugin paths under /wp-content/plugins/jet-blocks/ from unfamiliar source addresses.
- Repeated requests to plugin AJAX or REST endpoints associated with jet-blocks without a valid authenticated session cookie.
- Anomalous outbound response sizes for jet-blocks requests that suggest bulk data retrieval.
Detection Strategies
- Inventory WordPress sites and identify installations of JetBlocks For Elementor at version 1.5.0 or earlier.
- Deploy web application firewall rules that alert on anonymous access to JetBlocks plugin endpoints returning structured data.
- Correlate web server access logs for anomalous scanning patterns targeting Elementor and Crocoblock plugin paths.
Monitoring Recommendations
- Enable verbose logging on the WordPress reverse proxy or WAF for all /wp-content/plugins/jet-blocks/ request paths.
- Track HTTP response codes and payload sizes for JetBlocks endpoints to baseline normal behavior and flag deviations.
- Monitor threat intelligence feeds for exploitation activity or new proof-of-concept publications referencing CVE-2026-61976.
How to Mitigate CVE-2026-61976
Immediate Actions Required
- Identify all WordPress sites running JetBlocks For Elementor <= 1.5.0 across your estate.
- Apply the vendor-provided update as soon as a fixed version is available from Crocoblock.
- Restrict network access to WordPress administrative and plugin endpoints where operationally feasible.
Patch Information
At the time of publication, the vulnerability affects JetBlocks For Elementor from n/a through 1.5.0. Administrators should consult the Patchstack Vulnerability Report and Crocoblock's official channels for the fixed release, and upgrade the plugin through the WordPress plugin management console once available.
Workarounds
- Temporarily deactivate the JetBlocks For Elementor plugin if it is not business-critical until a patched version is deployed.
- Deploy WAF rules to block unauthenticated requests to plugin endpoints that return sensitive data.
- Rotate any secrets, tokens, or credentials that may have been embedded in plugin configuration and exposed.
# Example: WP-CLI commands to audit and disable the vulnerable plugin
wp plugin list --name=jet-blocks --fields=name,status,version
wp plugin deactivate jet-blocks
# After the vendor releases a fixed version:
wp plugin update jet-blocks
