CVE-2025-58675 Overview
CVE-2025-58675 is a Cross-Site Request Forgery (CSRF) vulnerability [CWE-352] affecting the tryinteract Interact: Embed A Quiz On Your Site WordPress plugin (interact-quiz-embed). The flaw impacts all plugin versions up to and including 3.1. An attacker can craft a malicious web page that triggers unauthorized state-changing actions when a logged-in site administrator visits the page. Exploitation requires user interaction and does not require authentication from the attacker. Successful exploitation results in a limited integrity impact on the target WordPress site without affecting confidentiality or availability.
Critical Impact
An attacker who lures an authenticated WordPress administrator to a malicious page can perform unauthorized actions in the context of the plugin, leading to unintended modifications of plugin state or configuration.
Affected Products
- WordPress plugin: Interact: Embed A Quiz On Your Site (interact-quiz-embed)
- Versions from n/a through 3.1 (inclusive)
- Vendor: tryinteract

Technical Details for CVE-2025-58675
Vulnerability Analysis
The vulnerability stems from missing or improperly implemented CSRF protections in the interact-quiz-embed plugin. The plugin fails to validate that state-changing HTTP requests originate from a trusted, user-initiated action within the WordPress admin interface. Without a properly verified anti-CSRF token (WordPress nonce), the plugin cannot distinguish between legitimate administrator actions and forged requests initiated by external sites.
Because the attack vector is network-based and requires user interaction, exploitation depends on social engineering. An attacker must convince an authenticated administrator to click a link or load attacker-controlled content while a valid WordPress session is active. The integrity impact is limited in scope, and the vulnerability does not directly expose sensitive data or degrade site availability.
Root Cause
The root cause is the absence of proper request origin validation for privileged plugin actions. WordPress plugins typically enforce CSRF protection using wp_nonce_field() on forms and check_admin_referer() or wp_verify_nonce() on request handlers. When these checks are missing, incomplete, or applied inconsistently, any authenticated session can be leveraged by a remote attacker through a forged request.
Attack Vector
An attacker hosts a malicious page containing an auto-submitting HTML form or JavaScript that targets a vulnerable plugin endpoint on the victim's WordPress site. When an authenticated administrator visits the attacker-controlled page, the browser automatically includes the administrator's session cookies with the forged request. The plugin processes the request as legitimate and performs the intended state change. See the Patchstack CSRF Vulnerability Report for additional technical detail.
No verified public proof-of-concept code is available for this vulnerability at the time of writing.
Detection Methods for CVE-2025-58675
Indicators of Compromise
- Unexpected changes to Interact quiz plugin configuration, embedded quiz identifiers, or associated settings within the WordPress admin.
- Web server access logs showing POST requests to plugin endpoints with Referer headers pointing to external, untrusted domains.
- Administrator sessions performing plugin actions immediately after visiting external links or receiving targeted emails.
Detection Strategies
- Inspect WordPress audit logs for plugin configuration changes that do not correspond to known administrator activity.
- Monitor HTTP request headers to plugin admin endpoints for missing or invalid _wpnonce parameters.
- Correlate administrator browsing telemetry with subsequent state-changing requests to wp-admin endpoints belonging to interact-quiz-embed.
Monitoring Recommendations
- Enable a WordPress audit-logging plugin to capture all plugin setting changes with associated user, IP, and referer data.
- Alert on external Referer values on any authenticated wp-admin POST request.
- Review administrator account activity regularly, focusing on off-hours or unusual browsing patterns preceding configuration changes.
How to Mitigate CVE-2025-58675
Immediate Actions Required
- Identify all WordPress sites running the Interact: Embed A Quiz On Your Site plugin at version 3.1 or earlier.
- Restrict administrator browsing on machines used to manage WordPress, and require administrators to log out of wp-admin when not actively using it.
- Review recent plugin configuration changes for any unauthorized modifications.
Patch Information
At the time of publication, the NVD record and referenced Patchstack advisory list the vulnerability as affecting versions up to and including 3.1. Site operators should check the WordPress plugin repository for a version newer than 3.1 and apply updates promptly. If no fixed release is available, consider deactivating the plugin.
Workarounds
- Deactivate and remove the interact-quiz-embed plugin until a patched version is available.
- Deploy a Web Application Firewall (WAF) rule that blocks POST requests to plugin admin endpoints when the Referer header is absent or points to an external domain.
- Enforce short WordPress session lifetimes and require administrators to authenticate from dedicated browser profiles.
- Train administrators to avoid clicking untrusted links while authenticated to wp-admin.
