On April 5, 2023 the Wordfence Threat Intelligence team initiated the responsible disclosure process for a vulnerability we discovered in WP Data Access, a WordPress plugin that is installed on over 10,000 sites. This flaw makes it possible for an authenticated attacker to grant themselves administrative privileges via a profile update, if the targeted site has the ‘Role Management’ setting enabled.
Wordfence Premium, Care, and Response users received a firewall rule to protect against any exploits targeting this vulnerability on April 5, 2023. Sites still using the free version of Wordfence will receive the same protection on May 5, 2023.
We performed our initial outreach to the developer on April 5, 2023, the same day we discovered the vulnerability. We received a response the same day and sent over the full details. The developer released a patch swiftly the next day on April 6, 2023.
