CVE-2025-32255: ERA404 StaffList Information Disclosure

CVE-2025-32255 Overview

CVE-2025-32255 is an information disclosure vulnerability in the ERA404 StaffList plugin for WordPress. The flaw exposes sensitive system information to unauthorized actors and is classified under [CWE-497] (Exposure of Sensitive System Information to an Unauthorized Control Sphere). The vulnerability affects all versions of StaffList up to and including 3.2.7. An unauthenticated remote attacker can retrieve embedded sensitive data over the network without user interaction. The issue is tracked with an EPSS score of 0.514% (40.161 percentile) as of the July 2026 scoring window.

Critical Impact
Unauthenticated remote attackers can retrieve embedded sensitive data from vulnerable StaffList installations, potentially exposing information useful for follow-on attacks against the WordPress site.

Affected Products

Technical Details for CVE-2025-32255

Vulnerability Analysis

The StaffList plugin embeds sensitive system information within resources accessible to unauthorized clients. Because the plugin does not restrict access to this data, remote actors can query the exposed endpoints and retrieve information intended for privileged contexts only. The disclosure vector requires no authentication and no user interaction, making automated harvesting straightforward. Attackers commonly use such disclosures to fingerprint installations, identify additional weaknesses, and prepare targeted follow-on attacks. The vulnerability aligns with [CWE-497], which addresses the improper exposure of internal system details to actors outside the intended trust boundary.

Root Cause

The root cause is the inclusion of sensitive system information in plugin outputs or resources that lack access controls. The StaffList plugin does not enforce authorization checks or scrub embedded data before serving it to unauthenticated requests. This design allows any network-adjacent actor to retrieve details that should remain internal to the WordPress instance.

Attack Vector

Exploitation occurs over the network against exposed WordPress endpoints served by the vulnerable plugin. An attacker sends crafted HTTP requests to plugin-provided resources and receives responses containing embedded sensitive data. No credentials, elevated privileges, or user interaction are required. Refer to the Patchstack Vulnerability Report for additional technical context.

Detection Methods for CVE-2025-32255

Indicators of Compromise

Unauthenticated HTTP GET requests targeting /wp-content/plugins/stafflist/ paths from unfamiliar IP addresses
Repeated automated scanning against WordPress installations enumerating plugin directories
Web server access logs showing successful 200 responses to plugin resource requests without prior authentication

Detection Strategies

Inventory WordPress installations and identify sites running the StaffList plugin version 3.2.7 or earlier
Correlate web access logs for anomalous request patterns against StaffList endpoints
Deploy web application firewall (WAF) rules that flag or block direct requests to plugin internal resources

Monitoring Recommendations

Enable verbose access logging on WordPress hosts and forward logs to a centralized analytics platform
Alert on outbound data volume anomalies from web servers hosting the plugin
Track plugin version deployments across environments to detect unpatched instances

How to Mitigate CVE-2025-32255

Immediate Actions Required

Identify all WordPress sites with the ERA404 StaffList plugin installed and record installed versions
Update StaffList to a version later than 3.2.7 as soon as a fixed release is available from the vendor
Restrict direct HTTP access to plugin internal files at the web server or WAF layer

Patch Information

The vulnerability affects StaffList versions through 3.2.7. Administrators should consult the Patchstack Vulnerability Report for current fix availability and apply vendor-supplied updates as soon as they are released.

Workarounds

Deactivate and remove the StaffList plugin until a patched version is deployed
Configure WAF rules to block unauthenticated requests to plugin resource paths
Apply web server access controls restricting direct requests to wp-content/plugins/stafflist/ internal files

bash

# Example nginx configuration to restrict direct access to plugin internals
location ~* /wp-content/plugins/stafflist/.*\.(php|inc|log|txt)$ {
    deny all;
    return 403;
}
