CVE-2025-24582: 12 Step Meeting List Info Disclosure Flaw

CVE-2025-24582 Overview

CVE-2025-24582 is a sensitive data exposure vulnerability in the AA Web Servant 12 Step Meeting List WordPress plugin. The flaw is classified under [CWE-201] Insertion of Sensitive Information Into Sent Data. It affects all plugin versions up to and including 3.16.5. An unauthenticated remote attacker can retrieve embedded sensitive data through network-accessible endpoints without user interaction. The issue impacts confidentiality but does not compromise integrity or availability of the affected WordPress installations.

Critical Impact
Unauthenticated attackers can retrieve sensitive information embedded in responses served by the 12 Step Meeting List plugin, exposing data intended to remain private within the WordPress site.

Affected Products

AA Web Servant 12 Step Meeting List plugin versions up to and including 3.16.5
WordPress sites with the 12-step-meeting-list plugin installed and activated
Any deployment relying on the plugin to manage meeting listings with private or restricted fields

Technical Details for CVE-2025-24582

Vulnerability Analysis

The plugin includes sensitive data in responses that should not contain it. The exposed data is embedded in server output accessible over the network. Because the attack vector is network-based and requires no privileges or user interaction, any anonymous visitor can trigger the disclosure. The impact is limited to confidentiality of specific fields returned by the plugin, without altering site data or availability.

Root Cause

The root cause is [CWE-201] Insertion of Sensitive Information Into Sent Data. The plugin fails to strip or restrict sensitive attributes from data structures before serializing them into HTTP responses. Fields intended for administrative or internal use are returned alongside public content. The absence of a server-side filter that scopes response contents based on the requesting user's authorization enables the exposure.

Attack Vector

An attacker sends unauthenticated HTTP requests to endpoints served by the 12-step-meeting-list plugin. The response contains the embedded sensitive fields that the plugin should have filtered. Because no privilege check is required, the exposure can be discovered through routine crawling or manual review of the plugin's public output. Refer to the Patchstack Vulnerability Report for detailed vulnerable request patterns.

Detection Methods for CVE-2025-24582

Indicators of Compromise

Unauthenticated HTTP GET requests to /wp-json/ and /wp-admin/admin-ajax.php endpoints referencing the 12-step-meeting-list plugin
Access log entries showing repeated requests to plugin routes from unfamiliar IP addresses or automated user agents
Presence of sensitive fields such as private meeting metadata in publicly cached responses

Detection Strategies

Enumerate WordPress plugins on managed sites and flag any installation of 12-step-meeting-list at version 3.16.5 or earlier
Review web server access logs for high-volume, unauthenticated queries against plugin REST or AJAX endpoints
Compare returned JSON payloads to expected public schemas and alert on fields not intended for anonymous consumers

Monitoring Recommendations

Ingest WordPress web server and application logs into a centralized log platform for query-based analytics
Configure alerts for anomalous spikes in requests to 12-step-meeting-list endpoints from single sources
Track plugin version inventories over time and alert when vulnerable versions reappear after updates

How to Mitigate CVE-2025-24582

Immediate Actions Required

Update the 12 Step Meeting List plugin to a version later than 3.16.5 as soon as the vendor publishes a fixed release
Audit historical access logs for prior unauthenticated queries against plugin endpoints and assess data that may have been retrieved
Restrict administrative interfaces to trusted networks and enforce authentication for non-public plugin routes where feasible

Patch Information

The vulnerability affects 12 Step Meeting List versions from n/a through <= 3.16.5. Consult the Patchstack Vulnerability Report for the current fixed version and upgrade guidance. Apply the vendor's official patch through the WordPress plugin update mechanism.

Workarounds

Deactivate the 12-step-meeting-list plugin until a patched version is applied if the exposed fields are considered sensitive
Deploy a Web Application Firewall (WAF) rule to block or sanitize responses from plugin endpoints that leak sensitive fields
Apply reverse-proxy filtering to strip disallowed keys from JSON responses served under plugin routes

bash

# Example WAF rule concept to block anonymous access to plugin REST endpoints
SecRule REQUEST_URI "@rx /wp-json/.*12-step-meeting-list" \
    "id:1002401,phase:1,deny,status:403,log,msg:'Block anonymous access to 12-step-meeting-list endpoint'"
