Technical Details for CVE-2026-49077

Vulnerability Analysis

The vulnerability resides in the WP eMember WordPress plugin developed by Tips and Tricks HQ. The plugin manages paid membership functionality on WordPress sites and handles user account data, payment configuration, and access control settings.

The issue allows an unauthenticated attacker to retrieve embedded sensitive data through a network-reachable endpoint. The attack requires no privileges and no user interaction. According to the Patchstack advisory, the disclosure permits retrieval of information that the plugin embeds in responses or accessible resources.

The exposure is limited to confidentiality. The flaw does not by itself allow modification of plugin data or service disruption. However, disclosed information can support reconnaissance and follow-on attacks against the WordPress site or its users.

Root Cause

The root cause is a failure to restrict access to sensitive plugin data, classified under [CWE-497]. WP eMember exposes information through a control sphere that does not enforce authentication or authorization. The plugin embeds sensitive values in resources reachable by unauthenticated requests.

Attack Vector

An attacker sends a network request to the vulnerable WordPress endpoint exposed by WP eMember. No credentials, prior access, or user interaction are required. The server responds with sensitive data embedded in the plugin output. Because the attack vector is purely network-based, any internet-exposed WordPress site running WP eMember through v10.2.2 is reachable by remote attackers.

No public proof-of-concept exploit is currently listed in the NVD record, and the vulnerability is not present in the CISA Known Exploited Vulnerabilities catalog.

Detection Methods for CVE-2026-49077

Indicators of Compromise

Unauthenticated HTTP GET requests to WP eMember plugin paths under /wp-content/plugins/wp-emember/ from unfamiliar IP addresses
Repeated probing of WordPress endpoints associated with WP eMember resources or AJAX actions
Outbound responses from the WordPress site containing membership configuration or account-related fields delivered to unauthenticated clients

Detection Strategies

Inventory WordPress installations and identify sites running the WP eMember plugin at version v10.2.2 or earlier
Review web server access logs for anonymous requests targeting WP eMember files or query parameters
Correlate WordPress plugin version data with vulnerability feeds referencing CVE-2026-49077

Monitoring Recommendations

Enable verbose logging on the web server and WordPress application for plugin-related request paths
Forward WordPress and web server logs to a centralized analytics platform for anomaly review
Alert on bursts of unauthenticated requests to plugin endpoints that return non-empty response bodies

How to Mitigate CVE-2026-49077

Immediate Actions Required

Identify all WordPress sites running WP eMember at version v10.2.2 or earlier
Update WP eMember to a version released after v10.2.2 once the vendor publishes a fix
