CVE-2025-58010 Overview
CVE-2025-58010 is a Cross-Site Request Forgery (CSRF) vulnerability in the straightvisions GmbH SV Proven Expert WordPress plugin (sv-provenexpert). The flaw affects all plugin versions up to and including 2.0.06. An attacker can trick an authenticated site administrator into submitting a forged request that performs unwanted state-changing actions on the WordPress site. The vulnerability is classified under CWE-352: Cross-Site Request Forgery and requires user interaction to trigger.
Critical Impact
An attacker can modify plugin state on behalf of a logged-in administrator by luring the target to a malicious page, resulting in limited integrity impact on the WordPress site.
Affected Products
- straightvisions GmbH SV Proven Expert plugin for WordPress
- Plugin versions from n/a through 2.0.06
- WordPress sites with the sv-provenexpert plugin installed and active
Discovery Timeline
- 2025-09-22 - CVE-2025-58010 published to the National Vulnerability Database (NVD)
- 2026-06-17 - Last updated in NVD database
Technical Details for CVE-2025-58010
Vulnerability Analysis
The SV Proven Expert plugin exposes one or more state-changing actions that do not properly verify the origin of incoming requests. Because WordPress relies on nonce tokens and referer checks to protect privileged actions, the absence of these controls allows a remote attacker to forge requests that a browser will automatically authenticate using the victim's existing session cookies.
Exploitation requires that a logged-in user, typically an administrator, visit an attacker-controlled page while their WordPress session is active. The browser then submits the forged request to the vulnerable endpoint, and the plugin executes it as if it originated from the authenticated user. The impact is limited to integrity changes within the plugin's scope. No confidentiality or availability impact is expected based on the published scoring.
According to the Patchstack CSRF Vulnerability Report, the issue affects the plugin through version 2.0.06. The current EPSS probability is 0.131%.
Root Cause
The root cause is missing or insufficient CSRF protection on one or more privileged actions in the sv-provenexpert plugin. Specifically, the plugin does not validate a WordPress nonce (via wp_verify_nonce() or check_admin_referer()) before processing state-changing requests. This omission allows cross-origin form submissions from attacker-controlled pages to succeed against authenticated administrators.
Attack Vector
The attack is delivered over the network and requires user interaction. An attacker crafts a malicious HTML page containing an auto-submitting form or image tag that targets the vulnerable plugin endpoint on the victim's WordPress site. When an authenticated administrator visits the attacker's page, the browser attaches the WordPress authentication cookies and the request is processed. Delivery vectors typically include phishing emails, malicious advertisements, or forum posts linking to the exploit page.

Detection Methods for CVE-2025-58010
Indicators of Compromise
- Unexpected changes to SV Proven Expert plugin settings in the WordPress administration dashboard
- HTTP POST requests to sv-provenexpert plugin endpoints with a Referer header pointing to an external, untrusted domain
- Administrator actions recorded in WordPress logs that do not correspond to any known admin activity
- Requests to plugin admin endpoints lacking a valid _wpnonce parameter
Detection Strategies
- Inspect web server access logs for POST requests to wp-admin/admin.php and admin-ajax.php targeting sv-provenexpert actions where the Referer header is off-site
- Deploy a Web Application Firewall (WAF) rule that flags authenticated state-changing requests to the plugin without a WordPress nonce
- Enable a WordPress audit logging plugin to record administrator setting changes and correlate them with browsing activity
Monitoring Recommendations
- Alert on modifications to any option row in wp_options associated with the sv-provenexpert plugin outside of scheduled maintenance windows
- Monitor administrator user agents and source IPs for anomalous patterns coinciding with plugin configuration changes
- Track outbound clicks and email gateway logs for URLs matching known CSRF exploit hosting patterns
How to Mitigate CVE-2025-58010
Immediate Actions Required
- Update the SV Proven Expert plugin to a version later than 2.0.06 as soon as a fixed release is published by straightvisions GmbH
- Deactivate and remove the sv-provenexpert plugin if a patched version is not yet available and the plugin is not business-critical
- Instruct administrators to log out of WordPress sessions when not actively managing the site to shrink the exploitation window
Patch Information
Consult the Patchstack CSRF Vulnerability Report and the plugin listing on the WordPress plugin directory for the current fixed version. Apply the vendor patch through the WordPress admin Plugins screen or via wp-cli using wp plugin update sv-provenexpert.
Workarounds
- Restrict access to wp-admin by IP allowlist at the reverse proxy or WAF layer to reduce exposure of administrative endpoints
- Enforce SameSite=Lax or SameSite=Strict on WordPress authentication cookies to break cross-site request delivery in modern browsers
- Require administrators to use a dedicated browser profile for WordPress management to avoid session reuse on untrusted sites
# Configuration example: update the plugin via wp-cli
wp plugin update sv-provenexpert
wp plugin list --name=sv-provenexpert --fields=name,status,version
