Description
WordPress Plugin Ultimate Membership Pro is prone to a security bypass vulnerability. Exploiting this issue may allow attackers to perform otherwise restricted actions and subsequently generate an export containing PII (username, email address, IP address, User-Agent and so on), as well as generate authentication links by suppling an ID or Username. WordPress Plugin Ultimate Membership Pro version 8.6 is vulnerable; prior versions may also be affected.
Remediation
Update to plugin version 8.6.1 or latest
