CVE-2025-30822 Overview
CVE-2025-30822 is a Cross-Site Request Forgery (CSRF) vulnerability in the Hakik Zaman Custom Login Logo (ideal-wp-login-logo-changer) WordPress plugin. The flaw affects all plugin versions up to and including 1.1.7. An attacker who convinces an authenticated administrator to visit a crafted page can trigger unwanted state-changing actions in the plugin. The issue is tracked under CWE-352: Cross-Site Request Forgery and requires user interaction to succeed.
Critical Impact
Successful exploitation allows attackers to modify plugin settings on behalf of an authenticated WordPress administrator without their consent.
Affected Products
- Hakik Zaman Custom Login Logo (ideal-wp-login-logo-changer) plugin versions up to and including 1.1.7
- WordPress installations running the affected plugin
- Sites where administrators can be induced to visit attacker-controlled pages while logged in

Technical Details for CVE-2025-30822
Vulnerability Analysis
The Custom Login Logo plugin exposes administrative actions that change plugin configuration without validating the origin of the request. The plugin fails to verify a WordPress nonce or another anti-CSRF token before processing state-changing requests. An attacker crafts a malicious HTML page or link that submits a forged request to the vulnerable plugin endpoint. When a logged-in administrator loads that page, the browser attaches valid session cookies, and the request executes with administrative privileges.
Exploitation requires the administrator to interact with attacker-controlled content, which limits scale but remains realistic through phishing or watering-hole attacks. The confidentiality impact is none, and integrity is limited to plugin settings such as the custom login logo. Availability is unaffected. See the Patchstack Vulnerability Report for technical details.
Root Cause
The root cause is missing CSRF protection on administrative request handlers. The plugin does not call wp_verify_nonce() or check_admin_referer() before applying configuration changes, so any request bearing a valid administrator session cookie is honored regardless of origin.
Attack Vector
The attack vector is network-based and requires user interaction. An attacker hosts a page containing an auto-submitting form or image tag that targets the vulnerable plugin endpoint on a victim's WordPress site. When an authenticated administrator loads the page, the browser issues the forged request using the administrator's authenticated session.
No verified public exploit code is available at this time. The vulnerability mechanism is described in prose in accordance with source-grounded reporting.
Detection Methods for CVE-2025-30822
Indicators of Compromise
- Unexpected changes to the WordPress login page logo or Custom Login Logo plugin settings
- HTTP POST requests to plugin administrative endpoints originating from external Referer headers
- Administrator session activity immediately following visits to untrusted external sites
Detection Strategies
- Review WordPress audit logs for plugin option changes correlated with unusual referrers or user-agent strings
- Inspect web server access logs for POST requests to wp-admin endpoints belonging to the ideal-wp-login-logo-changer plugin without a matching prior GET for the settings page
- Alert on plugin setting modifications made outside approved administrator workflows or maintenance windows
Monitoring Recommendations
- Enable a WordPress activity logging plugin to capture setting changes with user, IP, and referrer context
- Forward web server and WordPress logs to a centralized log platform for correlation and retention
- Monitor for phishing campaigns targeting site administrators, as user interaction is required for exploitation
How to Mitigate CVE-2025-30822
Immediate Actions Required
- Identify all WordPress sites running the Custom Login Logo (ideal-wp-login-logo-changer) plugin at version 1.1.7 or earlier
- Deactivate the plugin until a patched version is confirmed installed
- Require administrators to log out of WordPress before browsing untrusted external sites
Patch Information
At the time of publication, the vendor advisory listed on the Patchstack Vulnerability Report tracks fix availability for versions after 1.1.7. Administrators should update to the latest plugin release once published or remove the plugin if no fix is available.
Workarounds
- Uninstall the Custom Login Logo plugin and replace its functionality with a maintained alternative that enforces nonce validation
- Restrict wp-admin access to trusted source IP addresses using web server or WAF rules
- Deploy a web application firewall rule that blocks state-changing requests to plugin endpoints lacking a valid same-origin Referer and WordPress nonce
# Example: disable the vulnerable plugin via WP-CLI
wp plugin deactivate ideal-wp-login-logo-changer
wp plugin delete ideal-wp-login-logo-changer
