ProfilePress: Sensitive information exposure via shortcode injection

CVE-2026-92536High 8.8

← All vulnerabilities

Summary

The ProfilePress WordPress plugin (wp-user-avatar) up to and including version 4.17.4 exposes data of other users. An attacker with a Subscriber account can inject shortcodes that reveal other members' email addresses, login names and registration dates. If user registration is enabled, unauthenticated attackers may be able to exploit the same flaw through the plugin's registration handler.

Affected

  • ProfilePress (wp-user-avatar) versions 0 to and including 4.17.4

Fixed in

Unknown. No vendor advisory or confirmed fixed version was found. Do not assume that 4.17.5 is safe, because conflicting third-party records exist. Install the latest release and verify the fixed version against the vendor changelog or the Wordfence entry.

Workaround

  • Disable public registration (users_can_register) if it is not needed.
  • Review Subscriber accounts and remove unknown or unused ones.
  • Limit Member Directory and [pp-custom-html] use on public pages until a fix is confirmed.
  • A WAF rule set is not a fix.

Exploitation

  • No in-the-wild exploitation is known in the sources checked.
  • No public proof of concept was found.
  • CISA SSVC: exploitation none, automatable no. The CISA KEV catalog was not checked directly.

Our recommendation

  • Update ProfilePress to the latest release and confirm the fixed version.
  • Disable public registration if it is not required.
  • Review Subscriber accounts and remove unused ones.
  • Check whether personal data was exposed. Under the revised Swiss FADP, this may require an assessment and possibly a report.
  • Keep plugins updated on a regular schedule.

PoC-in-GitHub, Metasploit and Exploit-DB list nothing for this CVE.

Original description (NVD)

The Paid Membership Plugin, Ecommerce, User Registration Form, Login Form, User Profile & Restrict Content – ProfilePress plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 4.17.4 via the get_user_profile_structure. This makes it possible for authenticated attackers, with subscriber-level access and above, to extract other users' email addresses, login names, and registration dates via the Member Directory's per-row user rebinding when attacker-controlled base64 payloads in the [pp-custom-html] shortcode invoke [profile-email], [profile-username], and [profile-date-registered]. When the WordPress users_can_register option is enabled, unauthenticated attackers can also exploit this vulnerability by supplying the split shortcode fragments through the plugin's own registration handler, which processes the reg_nickname and reg_bio fields without a nonce requirement.
