Deeper analysis
CVE-2025-14844 is a missing authentication vulnerability (CWE-639) in the Membership Plugin – Restrict Content for WordPress, affecting all versions up to and including 3.2.16. The issue resides in the 'rcp_stripe_create_setup_intent_for_saved_card' function within the plugin's Stripe gateway integration at core/includes/gateways/stripe/functions.php. Due to a missing capability check and failure to validate a user-controlled key, the function exposes sensitive Stripe SetupIntent client_secret values.
Unauthenticated attackers can exploit this vulnerability over the network with low attack complexity and no user interaction required, per its CVSS v3.1 base score of 8.2 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:L/A:N). Exploitation allows remote attackers to leak Stripe SetupIntent client_secret values for any membership, granting high confidentiality impact and limited integrity impact by compromising payment setup intents without affecting availability.
Mitigation is available in version 3.2.17 of the plugin, as detailed in WordPress plugin repository changeset 3438168, which addresses the flaws in core/includes/gateways/stripe/functions.php. Practitioners should urge site administrators to update immediately, verify Stripe configurations, and monitor for unauthorized SetupIntent access using Stripe's API documentation.
