ProfilePress Authorization Bypass

Authenticated attackers with subscriber-level access can obtain paid lifetime membership plans in the ProfilePress WordPress plugin (≤4.16.11) without payment by exploiting a missing ownership verification flaw. The vulnerability allows hijacking of another user's active subscription during checkout to manipulate proration calculations. With a 7.1 CVSS score, low attack complexity, and requiring only low-privilege authentication, this presents a significant revenue loss risk for sites using ProfilePress for paid memberships. No public exploit identified at time of analysis, though EPSS data not available. Vendor patch released in version 4.16.12.

Arbitrary shortcode execution in ProfilePress plugin for WordPress (all versions up to 4.16.11) allows unauthenticated attackers to execute arbitrary shortcodes by injecting malicious code into billing field values during checkout, potentially leading to information disclosure or content manipulation. The vulnerability stems from insufficient sanitization of user-supplied input before shortcode processing. Wordfence has documented this issue with a CVSS score of 6.5 and no confirmed active exploitation at time of analysis.
