CVE-2026-119980: The UsersWP – Front-end login form, User Registration, User Profile & Members Directory plugin for WordPress is vulnerable to unauthorized account access via Use of Predictable Password in all versions up to, and including, 1.2.78 The vulnerability exists because `get_dummy_user_passowrd()` derives the shared password for all 25 built-in dummy user accounts as the first 15 characters of `substr(hash('SHA256', AUTH_KEY . site_url()), 0, 25)`, while the full 25-character value of that same hash is simultaneously embedded in the hidden `uwp_register_hash` field rendered on every registration form response — reachable without authentication via both the public `/register/` page and the `wp_ajax_nopriv_uwp_ajax_register_form` AJAX handler, even when user registration is disabled. This makes it possible for unauthenticated attackers to recover the dummy user password directly from a single HTTP request and use it to authenticate as any of the 25 built-in dummy accounts (such as antawn, chynna, or kiki) through `wp-login.php`, potentially achieving privilege escalation if any dummy account holds an elevated role. Exploitation requires that an administrator has previously created dummy users via the plugin's Tools page.
The exploitability of CVE-2026-119980 depends on two key factors: attack complexity (the level of effort required to execute an exploit) and privileges required (the access level an attacker needs).
With low attack complexity and no required privileges, CVE-2026-119980 is an easy target for cybercriminals. Organizations should prioritize immediate mitigation measures to prevent unauthorized access and data breaches.
A lower complexity and fewer privilege requirements make exploitation easier. Security teams should evaluate these aspects to determine the urgency of mitigation strategies, such as patch management and access control policies.
Attack Complexity (AC) measures the difficulty in executing an exploit. A high AC means that specific conditions must be met, making an attack more challenging, while a low AC means the vulnerability can be exploited with minimal effort.
Privileges Required (PR) determine the level of system access necessary for an attack. Vulnerabilities requiring no privileges are more accessible to attackers, whereas high privilege requirements limit exploitation to authorized users with elevated access.
Above is the CVSS Sub-score Breakdown for CVE-2026-119980, illustrating how Base, Impact, and Exploitability factors combine to form the overall severity rating. A higher sub-score typically indicates a more severe or easier-to-exploit vulnerability.
Below is the Impact Analysis for CVE-2026-119980, showing how Confidentiality, Integrity, and Availability might be affected if the vulnerability is exploited. Higher values usually signal greater potential damage.
