Is Wp Social Login and Register Social Counter safe? Known vulnerabilities and latest version

The Wp Social Login and Register Social Counter plugin for WordPress is vulnerable to Authentication Bypass in all versions up to, and including, 3.2.2. This is due to the social login REST callback registered at `/wp-json/wslu-social-login/type/{provider}/` with `permission_callback => __return_true` locating an existing WordPress account solely by the email string returned from the OAuth provider and calling `wp_set_auth_cookie()` without a password check, while the only verification guard — `!empty($getProfile->emailVerified)` in `inc/admin-create-user.php` — is a no-op for the bundled Hybridauth Facebook and Twitter adapters, both of which assign the raw email string rather than a boolean verified flag to `emailVerified`. This makes it possible for unauthenticated attackers to obtain a fully authenticated session as any existing WordPress user, including Administrators, whose registered email address can be presented through a configured Facebook or Twitter login on the target site. Exploitation requires only that the attacker control an OAuth account whose provider-returned email matches the target account's registered WordPress email address; no local credentials, nonce, or prior foothold is needed.

The Wp Social Login and Register Social Counter plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Avatar Alt Attribute via Arbitrary User Meta Write in all versions up to, and including, 3.2.1 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. This requires the attacker to chain two steps: invoking the nonce-only dismiss_ajax_call endpoint (nonce accessible to Subscribers via any wp-admin page) to set the xs_social_profile_image meta flag on their own account, which activates the unescaped img output branch in xs_social_get_avatar, and then setting their display name to a script payload that core's ENT_NOQUOTES handling preserves unescaped.

The Wp Social Login and Register Social Counter plugin for WordPress is vulnerable to missing authorization in versions up to, and including, 3.1.3. This is due to the REST routes wslu/v1/check_cache/{type}, wslu/v1/save_cache/{type}, and wslu/v1/settings/clear_counter_cache being registered with permission_callback set to __return_true and lacking capability or nonce validation in their handlers. This makes it possible for unauthenticated attackers to clear or overwrite the social counter cache via crafted REST requests.

The Wp Social Login and Register Social Counter plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 3.1.0. This is due to missing or incorrect nonce validation on the counter_access_key_setup() function. This makes it possible for unauthenticated attackers to update social login provider settings via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.

The Wp Social Login and Register Social Counter plugin for WordPress is vulnerable to authentication bypass in all versions up to, and including, 3.0.7. This is due to insufficient verification on the user being returned by the social login token. This makes it possible for unauthenticated attackers to log in as any existing user on the site, such as an administrator, if they have access to the email and the user does not have an already-existing account for the service returning the token.

The Wp Social Login and Register Social Counter plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the /wp_social/v1/ REST API endpoint in all versions up to, and including, 3.0.0. This makes it possible for unauthenticated attackers to enable and disable certain providers for the social share and login features.
