CVE-2026-57665 Overview
CVE-2026-57665 is an unauthenticated Insecure Direct Object References (IDOR) vulnerability affecting the GravityView plugin for WordPress in versions up to and including 3.0.0. The flaw allows remote attackers to access records belonging to other users by manipulating object identifiers in requests, without requiring authentication or user interaction. The issue is tracked under CWE-639: Authorization Bypass Through User-Controlled Key and stems from missing authorization checks on direct object references exposed by the plugin.
Critical Impact
Unauthenticated attackers can access entry data managed by GravityView by directly referencing object identifiers, leading to disclosure of information intended for authorized users only.
Affected Products
- GravityView WordPress plugin versions <= 3.0.0
- WordPress sites running GravityView entry views with default access configurations
- Environments exposing GravityView-rendered entries to unauthenticated visitors

Technical Details for CVE-2026-57665
Vulnerability Analysis
GravityView renders and displays Gravity Forms entries on the front end of WordPress sites. The vulnerable versions accept user-controlled identifiers that reference stored entries but fail to validate whether the requesting user is authorized to view the referenced record. Because the flaw is reachable over the network with no privileges and no user interaction, any unauthenticated visitor able to reach the site can request records outside their intended scope.
The impact is limited to confidentiality of data exposed through the plugin. Integrity and availability of the host site are not directly affected. The Exploit Prediction Scoring System (EPSS) probability is 0.187% as of 2026-07-03, and no public exploit or CISA KEV entry is currently associated with this CVE.
Root Cause
The root cause is missing or insufficient authorization enforcement on object references handled by GravityView. When the plugin resolves an entry identifier supplied in a request, it does not verify that the caller has permission to view that specific entry. This is a canonical [CWE-639] pattern where authorization decisions rely on the requester supplying only their own identifier, an assumption trivially violated by tampering with the request.
Attack Vector
An unauthenticated remote attacker sends crafted HTTP requests to a GravityView-rendered endpoint, substituting entry or object identifiers with values belonging to other users. The server returns the referenced entry data without checking ownership or role. No credentials, tokens, or social engineering are required. Refer to the Patchstack Vulnerability Advisory for advisory-level technical details. No verified proof-of-concept code is available; the vulnerability mechanism is described in prose only.
Detection Methods for CVE-2026-57665
Indicators of Compromise
- Repeated HTTP requests to GravityView view endpoints with sequentially incrementing or fuzzed entry identifiers.
- Access to entry identifiers from source IP addresses that never authenticated or completed a form submission.
- Web server access logs showing unauthenticated retrieval of GravityView entry URLs across a broad range of IDs.
Detection Strategies
- Inspect WordPress access logs for unauthenticated GET requests targeting GravityView view URLs with varying entry or object identifier parameters.
- Correlate high-volume enumeration patterns against GravityView routes with 200 OK responses and non-trivial response sizes.
- Alert on requests to GravityView endpoints originating from IPs that have not established a session cookie.
Monitoring Recommendations
- Enable verbose access logging on WordPress front-end pages that embed GravityView shortcodes or blocks.
- Monitor Web Application Firewall (WAF) telemetry for IDOR enumeration signatures against /?gv_entry=, /entry/, and related paths.
- Track anomalous request-rate spikes to plugin-generated URLs and review response payload sizes for data exfiltration patterns.
How to Mitigate CVE-2026-57665
Immediate Actions Required
- Upgrade GravityView to a version later than 3.0.0 that includes the vendor-supplied authorization fix.
- Audit all published GravityView views and restrict them to authenticated roles where entry data is sensitive.
- Review historical web logs for evidence of prior enumeration of entry identifiers.
Patch Information
Consult the Patchstack Vulnerability Advisory for the fixed version reference and update guidance. Apply the vendor patch through the WordPress plugin update mechanism and verify the installed version after upgrade.
Workarounds
- Temporarily disable public GravityView views that render sensitive entry data until the plugin is upgraded.
- Restrict access to pages embedding GravityView shortcodes using WordPress role-based access controls or membership plugins.
- Deploy WAF rules to block unauthenticated requests carrying entry identifier parameters to GravityView endpoints.
# Configuration example
# Verify installed GravityView version via WP-CLI and update if <= 3.0.0
wp plugin get gravityview --field=version
wp plugin update gravityview
