Multiple Vulnerabilities Patched in Shield Security
On March 20, 2023, the Wordfence Threat Intelligence team began the responsible disclosure process for two vulnerabilities in Shield Security, a security plugin with over 50,000 installations. One of these vulnerabilities allowed unauthenticated attackers to inject malicious JavaScript into an administrator dashboard in some configurations, while another allowed authenticated attackers to spoof log entries into the same dashboard, which could also be used to exploit the first vulnerability in configurations where the unauthenticated technique was not viable.
We received a response and sent over full disclosure, and a patched version, 17.0.18, was released the same day.
Wordfence Premium, Care, and Response users received a firewall rule to protect against any exploits targeting this vulnerability on March 20, 2023. Sites still using the free version of Wordfence received the same protection on April 19, 2023.
