CVE-2026-49058 Overview
CVE-2026-49058 is an unauthenticated privilege escalation vulnerability affecting the LoginPress Pro WordPress plugin in versions up to and including 6.2.2. The flaw is classified under [CWE-266: Incorrect Privilege Assignment] and allows remote attackers to gain elevated privileges on a target WordPress site without prior authentication. Patchstack tracks this issue as a network-exploitable weakness requiring no user interaction. Successful exploitation grants attackers administrative control over the affected WordPress instance, exposing site content, user data, and underlying server resources.
Critical Impact
Remote, unauthenticated attackers can escalate privileges to administrator on WordPress sites running LoginPress Pro 6.2.2 or earlier, leading to full site compromise.
Affected Products
- LoginPress Pro WordPress plugin versions <= 6.2.2
- WordPress installations with LoginPress Pro active
- Multi-site WordPress deployments running vulnerable plugin builds

Technical Details for CVE-2026-49058
Vulnerability Analysis
The vulnerability resides in the LoginPress Pro plugin, which extends the standard WordPress login experience with custom branding, social login, and access controls. According to the Patchstack WordPress Vulnerability advisory, the plugin assigns privileges incorrectly during specific authentication or user-handling flows. An unauthenticated attacker can interact with exposed plugin endpoints to obtain a session or role beyond what the request context should permit.
Because the flaw is reachable over the network and requires no credentials, attackers can target exposed WordPress sites directly. The CWE-266 classification indicates the plugin grants higher privileges than warranted, bypassing WordPress role enforcement. Once an attacker assumes an administrator role, they can install arbitrary plugins, upload PHP payloads, and pivot to the underlying host.
Root Cause
The root cause is incorrect privilege assignment within the LoginPress Pro authentication or user-management logic. The plugin fails to validate that the requester is authorized to assume the resulting role. This permits role elevation through crafted requests against plugin-exposed endpoints rather than through legitimate WordPress capability checks.
Attack Vector
The attack vector is network-based and unauthenticated. An attacker sends a crafted HTTP request to a vulnerable LoginPress Pro endpoint on a target WordPress site. The plugin processes the request and grants elevated privileges without verifying caller identity or capability. No social engineering or user interaction is required, which makes mass-scanning and automated exploitation practical.
The vulnerability mechanism is described in the Patchstack advisory. No public proof-of-concept exploit has been published at the time of writing.
Detection Methods for CVE-2026-49058
Indicators of Compromise
- Unexpected creation of WordPress administrator accounts in wp_users and wp_usermeta tables
- New or modified plugin and theme files in wp-content/ with recent timestamps
- Outbound connections from the web server to unfamiliar IPs following requests to LoginPress Pro endpoints
- Web server access logs showing anonymous POST or GET requests to plugin AJAX or REST routes immediately followed by privileged actions
Detection Strategies
- Inventory WordPress sites and identify deployments running LoginPress Pro <= 6.2.2
- Hunt for newly registered administrator users created without a corresponding authenticated session in access logs
- Review wp-content/uploads/ and plugin directories for PHP files uploaded after suspicious LoginPress Pro endpoint activity
- Correlate WordPress audit logs with web server logs to flag privilege role changes attributable to unauthenticated requests
Monitoring Recommendations
- Enable WordPress audit logging to capture user creation, role changes, and plugin or theme installation events
- Forward web server, PHP, and WordPress logs to a centralized analytics platform for retention and correlation
- Alert on first-seen administrator accounts and on plugin or theme installations outside change-management windows
- Monitor for shell command execution originating from the www-data or PHP-FPM service account on hosts running WordPress
How to Mitigate CVE-2026-49058
Immediate Actions Required
- Update LoginPress Pro to a version later than 6.2.2 as soon as the vendor publishes a fixed release
- If no patched version is available, deactivate and remove the LoginPress Pro plugin until a fix is released
- Audit all WordPress administrator and editor accounts and remove any unauthorized users
- Rotate credentials, WordPress secret keys in wp-config.php, and API tokens for any site that may have been exposed
Patch Information
Refer to the Patchstack advisory for LoginPress Pro for the current patch status and fixed version availability. Apply the vendor-supplied update through the WordPress plugin manager or by replacing the plugin files with the patched release.
Workarounds
- Place the WordPress site behind a web application firewall and block requests targeting LoginPress Pro AJAX and REST endpoints
- Restrict access to /wp-admin/ and /wp-login.php by source IP where operationally feasible
- Disable user registration in WordPress settings until the plugin is patched or removed
- Enforce multi-factor authentication on all administrator accounts to limit post-exploitation reuse of credentials
