Low risk8th percentile - higher than 8% of all known CVEs
Summary
The Wp Social Login and Register Social Counter plugin for WordPress in versions up to and including 3.2.1 is vulnerable to Stored Cross-Site Scripting via Avatar Alt Attribute and Arbitrary User Meta Write due to insufficient input sanitization and output escaping. The attacker must chain two steps: invoking the nonce-only dismiss_ajax_call endpoint to set the xs_social_profile_image meta flag, then setting their display name to a script payload.
Risk Assessment
An authenticated attacker with subscriber-level access or higher can inject arbitrary scripts into pages that execute in the browser of any user visiting the injected page.
Recommendation
Update the Wp Social Login and Register Social Counter plugin to a version newer than 3.2.1 or disable it until a fix is released.
Other vulnerabilities in Wp Social Login and Register Social Counter
See all- CVE-2026-103898High
The Wp Social Login and Register Social Counter plugin for WordPress (up to 3.2.2) is vulnerable to Authentication Bypass. The social login REST callback locates an account by the email returned from the OAuth provider and sets an authentication cookie without a password check, while the only verification guard is a no-op for bundled Facebook and Twitter adapters. This allows unauthenticated attackers to obtain a session as any user, including Administrators, if they control an OAuth account with a matching email.
- CVE-2025-13620Medium
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.
Original NVD description (English source)
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.
