Subscriber-level privilege escalation via unchecked option update
Published May 17, 2024 · Updated Apr 28, 2026
Privilege escalation in Sirv for WordPress 7.2.2 and earlier allows remote authenticated users to update arbitrary site options. The sirv_dismiss_notice() function accepts an option name and updates it without a capability check, allowing Subscriber accounts to alter options outside their role. Exploitation requires a WordPress account with Subscriber privileges, and the resulting option changes permit privilege escalation within the site.
