Unauthenticated availability-impacting broken access control affects the ThemeGrill User Registration WordPress plugin versions 5.1.2 and earlier, allowing remote attackers to invoke privileged actions without credentials. The CVSS 7.5 score (AV:N/AC:L/PR:N/UI:N) reflects pure availability impact (A:H) with no confidentiality or integrity loss, and no public exploit identified at time of analysis. The flaw is classified as CWE-862 Missing Authorization and tracked by Patchstack and ENISA EUVD-2026-36911.
Reflected cross-site scripting in the wpeverest User Registration plugin for WordPress (all versions up to and including 5.1.5) lets remote attackers inject arbitrary JavaScript that executes in a victim's browser when they follow a crafted link. The CVSS scope-change rating (7.1) reflects that injected script can act beyond the vulnerable component, but practical impact is bounded by the privileges of whichever user is lured into clicking. There is no public exploit identified at time of analysis, EPSS risk is negligible (0.03%, 10th percentile), and CISA SSVC records no known exploitation.
A privilege escalation vulnerability exists in the wpeverest User Registration WordPress plugin through version 4.4.9 due to incorrect privilege assignment (CWE-266). This flaw allows authenticated or unauthenticated attackers to escalate their privileges within the plugin, potentially gaining administrative access or elevated capabilities. No CVSS score, EPSS data, or KEV status has been published, limiting quantification of real-world exploitation risk, though the vulnerability was reported by Patchstack and affects all installations running version 4.4.9 or earlier.
Broken authentication in WPEverest's User Registration WordPress plugin (versions 5.2.6 and below) permits subscriber-level authenticated users to bypass authentication controls and perform unauthorized actions beyond their role permissions. The CVSS:3.1 vector (AV:N/AC:L/PR:L/UI:N) confirms network-exploitable with low-privilege access required, producing limited but real integrity and availability impact. No public exploit code or active CISA KEV listing has been identified at time of analysis.
Broken access control in the WPEverest User Registration WordPress plugin (versions ≤5.2.6) permits unauthenticated remote attackers to bypass authorization checks and perform unauthorized actions within the registration subsystem, yielding limited integrity impact. The CVSS vector (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N) confirms exploitation requires no authentication, no user interaction, and no special configuration, though impact is constrained to integrity modifications with no confidentiality or availability effect. No public exploit code and no active exploitation have been identified at time of analysis.
The User Registration & Membership - Custom Registration Form, Login Form, and User Profile plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 's' parameter in all versions. Rated medium severity (CVSS 6.1), this vulnerability is remotely exploitable, no authentication required, low attack complexity. This Cross-Site Scripting (XSS) vulnerability could allow attackers to inject malicious scripts into web pages viewed by other users.
Missing Authorization vulnerability in wpeverest User Registration user-registration allows Exploiting Incorrectly Configured Access Control Security Levels.3.2.1. Rated medium severity (CVSS 5.3), this vulnerability is remotely exploitable, no authentication required, low attack complexity. No vendor patch available.
The User Registration WordPress plugin before 3.0.4.2 does not sanitize and escape some of its settings, which could allow high-privilege users such as admin to perform Stored Cross-Site Scripting. Rated medium severity (CVSS 4.8), this vulnerability is remotely exploitable, low attack complexity. Public exploit code available and no vendor patch available.
The User Registration plugin for WordPress is vulnerable to PHP Object Injection in versions up to, and including, 3.0.1 via deserialization of untrusted input from the 'profile-pic-url' parameter. Rated high severity (CVSS 8.8), this vulnerability is remotely exploitable, low attack complexity. This Deserialization of Untrusted Data vulnerability could allow attackers to execute arbitrary code through malicious serialized objects.
The User Registration plugin for WordPress is vulnerable to arbitrary file uploads due to a hardcoded encryption key and missing file type validation on the 'ur_upload_profile_pic' function in. Rated critical severity (CVSS 9.9), this vulnerability is remotely exploitable, low attack complexity. Public exploit code available.
Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in wpeverest User Registration user-registration allows DOM-Based XSS.3.0. Rated medium severity (CVSS 5.9), this vulnerability is remotely exploitable, low attack complexity. No vendor patch available.
The User Registration WordPress plugin before 2.2.4.1 does not properly restrict the files to be uploaded via an AJAX action available to both unauthenticated and authenticated users, which could. Rated high severity (CVSS 7.5), this vulnerability is remotely exploitable, no authentication required, low attack complexity. Public exploit code available and no vendor patch available.
The User Registration WordPress plugin before 2.0.2 does not properly sanitise the user_registration_profile_pic_url value when submitted directly via the user_registration_update_profile_details. Rated medium severity (CVSS 5.4), this vulnerability is remotely exploitable, low attack complexity. Public exploit code available and no vendor patch available.
