CVE-2025-32258 Overview
CVE-2025-32258 is a Missing Authorization vulnerability [CWE-862] in the InfoGiants Simple Website Logo plugin for WordPress. The flaw affects all versions from an unspecified starting version through 1.1. Attackers exploit incorrectly configured access control security levels to reach plugin functionality that should require elevated privileges.
The vulnerability is exploitable over the network without authentication or user interaction. It affects integrity of plugin-controlled settings but does not impact confidentiality or availability.
Critical Impact
Unauthenticated network attackers can invoke plugin actions that lack proper authorization checks, allowing modification of logo-related configuration on affected WordPress sites.
Affected Products
- InfoGiants Simple Website Logo WordPress plugin
- Versions up to and including 1.1
- WordPress sites running the simple-website-logo plugin

Technical Details for CVE-2025-32258
Vulnerability Analysis
The Simple Website Logo plugin exposes one or more endpoints that fail to verify the caller's capability or nonce before executing privileged operations. This is a Broken Access Control weakness classified under [CWE-862] Missing Authorization. The plugin trusts request parameters without confirming the requester holds the required WordPress role.
Exploitation requires only network access to the target WordPress site. No credentials or user interaction are required. The EPSS score is 0.299% at the 21.6 percentile, indicating limited observed exploitation activity as of the scoring date.
Successful exploitation lets an attacker manipulate plugin state controlled by the vulnerable handler. Integrity impact is limited, but a modified site logo or related settings can enable brand impersonation, phishing lures, or defacement scenarios on WordPress installations.
Root Cause
The root cause is the absence of current_user_can() capability checks and missing nonce validation on plugin action handlers. WordPress plugins must gate administrative actions behind both a capability check and a verified nonce. Without these checks, the endpoints treat any HTTP request as authorized.
Attack Vector
An unauthenticated attacker sends a crafted HTTP request to the vulnerable plugin handler on a target WordPress site. The plugin executes the requested action without validating the caller's authorization. See the Patchstack Vulnerability Report for technical details.
Detection Methods for CVE-2025-32258
Indicators of Compromise
- Unexpected modifications to the WordPress site logo or Simple Website Logo plugin settings
- HTTP POST requests to admin-ajax.php or plugin-specific endpoints from unauthenticated sources
- Changes to plugin option rows in the wp_options table without corresponding administrator login sessions
Detection Strategies
- Review WordPress access logs for requests to simple-website-logo plugin endpoints originating from unauthenticated sessions
- Correlate plugin setting changes in the database with authenticated administrator activity to identify anomalies
- Deploy a WordPress security scanner or web application firewall (WAF) rule that flags unauthenticated writes to plugin handlers
Monitoring Recommendations
- Enable audit logging for all plugin configuration changes on WordPress sites
- Alert on HTTP requests to plugin endpoints that return HTTP 200 without a valid authentication cookie
- Track the integrity of media library entries and site branding assets for unauthorized replacement
How to Mitigate CVE-2025-32258
Immediate Actions Required
- Identify all WordPress sites running the Simple Website Logo plugin at version 1.1 or earlier
- Deactivate and remove the plugin until a patched version becomes available from the vendor
- Audit recent changes to site logos and plugin settings for unauthorized modifications
Patch Information
No fixed version is listed in the NVD entry as of the last modification date. The affected version range is documented as up to and including 1.1. Monitor the Patchstack Vulnerability Report and the WordPress plugin repository for a patched release.
Workarounds
- Remove the simple-website-logo plugin from affected WordPress installations
- Restrict access to wp-admin/admin-ajax.php from untrusted networks using a WAF or reverse proxy rules
- Apply a virtual patch through a WordPress security plugin that enforces capability checks on the vulnerable endpoints
# Remove the vulnerable plugin using WP-CLI
wp plugin deactivate simple-website-logo
wp plugin uninstall simple-website-logo
