Several Critical Vulnerabilities Patched in UserPro WordPress Plugin

On May 1, 2023, the Wordfence Threat Intelligence team began the responsible disclosure process for multiple high and critical severity vulnerabilities they discovered in Kirotech’s UserPro plugin, which is actively installed on more than 20,000 WordPress websites.

Firewall rules were released by Wordfence in May and July. Wordfence states that they have no evidence to suggest that these vulnerabilities were known or targeted during this period, nor have we seen any evidence that they are currently being targeted.

We made an initial attempt to contact Kirotech, the vendor of UserPro, on May 1, 2023, but we did not receive a response until May 10, 2023, after many additional attempts. After providing full disclosure details, the developer released the first patch on July 27, 2023, and the final patch on October 31, 2023.

We urge users to update their sites to the latest patched version of UserPro, which is version 5.1.5 at the time of this writing, as soon as possible.
