Security readout for executives and security teams
Plain-English summary
A WordPress plugin for custom login and registration has a broken access control issue. A logged-in attacker may be able to perform actions the site did not intend to allow, causing limited integrity or availability impact. The provided sources do not identify data theft impact or a confirmed patched version.
Executive priority
Treat this as a moderate WordPress plugin risk. Prioritize sites that allow public account registration or support many low-privilege users. Remediation should be scheduled promptly, but this source bundle does not support emergency response claims such as active exploitation or critical impact.
Technical view
CVE-2025-46535 is a CWE-862 Missing Authorization flaw in AlphaEfficiencyTeam Custom Login and Registration, package slug ms-registration, reported through version 1.0.0. CVSS 3.1 is 5.4: network reachable, low complexity, low privileges required, no user interaction, with low integrity and availability impact.
Likely exposure
Exposure is most likely on WordPress sites running the Custom Login and Registration plugin, especially versions through 1.0.0. The affected version data is sparse, so teams should verify the plugin slug, installed version, and whether the plugin is active on public sites.
Exploitation context
The bundle does not show CISA KEV listing or cited evidence of active exploitation. The CVSS vector indicates exploitation requires an authenticated low-privilege account and no user interaction. Public details provided are limited and do not name affected endpoints or actions.
Researcher notes
The public record gives classification, severity, package slug, and high-level impact only. It does not provide endpoint, function, proof-of-concept, exploit status, or fixed-version detail. Avoid assuming unauthenticated exploitation because the CVSS vector requires low privileges.
Mitigation direction
- Inventory WordPress sites for the ms-registration plugin and installed version.
- Check vendor, WordPress, and Patchstack guidance for a fixed release or official mitigation.
- If no supported fix exists, disable or replace the plugin after change review.
- Restrict user registration and low-privilege account creation where business requirements allow.
- Review site roles and plugin settings for overly broad permissions.
Validation and detection
- Confirm whether Custom Login and Registration is installed and active.
- Record plugin version and compare against the through-1.0.0 affected range.
- Review WordPress users, roles, and recent privilege or content changes.
- Check web and application logs for suspicious authenticated activity.
- Validate remediation in staging before applying production changes.

Missing Authorization
Missing Authorization represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
