Users Manager Pn
Monthly
Arbitrary user metadata modification in Users Manager - PN plugin for WordPress (versions ≤1.1.15) allows unaneticated remote attackers to escalate privileges and hijack accounts. The vulnerability stems from flawed authorization logic in userspn_ajax_nopriv_server() that fails to verify authentication when user_id is supplied, combined with publicly exposed nonce values. Attackers can modify critical user metadata including userspn_secret_token for any WordPress user. CVSS 9.8 (Critical). EPSS data not available. No public exploit identified at time of analysis, but exploitation requires only HTTP requests with predictable parameters.
