The UsersWP – Front-end login form, User Registration, User Profile & Members Directory plugin for WP plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'badge' parameter in all versions up to, and including, 1.2.80 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The exploit is particularly effective against higher-privileged users — such as editors and administrators — who preview a Contributor's pending post containing the malicious shortcode.

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 getdummyuserpassowrd() derives the shared password for all 25 built-in dummy user accounts as the first 15 characters of substr(hash('SHA256', AUTHKEY . siteurl()), 0, 25), while the full 25-character value of that same hash is simultaneously embedded in the hidden uwpregisterhash field rendered on every registration form response — reachable without authentication via both the public /register/ page and the wpajaxnoprivuwpajaxregisterform 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 UsersWP WordPress plugin before 1.5.10 does not verify that a social login provider has confirmed ownership of an email address before using it to resolve an existing account, allowing unauthenticated attackers to log in as any user, including administrators, whose email address they can assert through a provider account of their own.

The UsersWP – Front-end login form, User Registration, User Profile & Members Directory plugin for WP plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Badge Widget Variable Substitution in all versions up to, and including, 1.2.69 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

The UsersWP – Front-end login form, User Registration, User Profile & Members Directory plugin for WP plugin for WordPress is vulnerable to blind Server-Side Request Forgery in all versions up to, and including, 1.2.58. This is due to insufficient URL origin validation in the processimagecrop() method when processing avatar/banner image crop operations. The function accepts a user-controlled URL via the uwpcrop POST parameter and only validates it using escurl() for sanitization and wpcheckfiletype() for extension verification, without enforcing that the URL references a local uploads file. The URL is then passed to uwpresizeThumbnailImage() which uses it in PHP image processing functions (getimagesize(), imagecreatefrom()) that support URL wrappers and perform outbound HTTP requests. This makes it possible for authenticated attackers with subscriber-level access and above to coerce the WordPress server into making arbitrary HTTP requests to attacker-controlled or internal network destinations, enabling internal network scanning and potential access to sensitive services.

Missing Authorization vulnerability in Stiofan UsersWP userswp allows Exploiting Incorrectly Configured Access Control Security Levels.This issue affects UsersWP: from n/a through <= 1.2.47.

The UsersWP – Front-end login form, User Registration, User Profile & Members Directory plugin for WordPress plugin for WordPress is vulnerable to time-based SQL Injection via the ‘uploadfileremove’ function and 'htmlvar' parameter in all versions up to, and including, 1.2.44 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for unauthenticated attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.

The UsersWP – Front-end login form, User Registration, User Profile & Members Directory plugin for WP plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'uwpprofile' and 'uwpprofileheader' shortcodes in all versions up to, and including, 1.2.42 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

The UsersWP WordPress plugin before 1.2.12 uses predictable filenames when an admin generates an export, which could allow unauthenticated attackers to download them and retrieve sensitive information such as IP, username, and email address

The UsersWP – Front-end login form, User Registration, User Profile & Members Directory plugin for WordPress plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's shortcode(s) in all versions up to, and including, 1.2.6 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers with contributor-level and above permissions to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
