CVE-2026-7465Network attack vector

Authenticated code execution via attacker-controlled block callback

Published May 30, 2026 · Updated May 30, 2026

Remote code execution in Brainstorm Force Spectra Legacy 2.19.25 and earlier allows remote authenticated users to execute server-side code. The block renderer accepts an attacker-controlled render_callback when a crafted uagb/-prefixed block is registered, then passes it to call_user_func() when a second block of the same type renders. Contributor-level post editing is required, and both blocks must render sequentially in the same page request to invoke the selected PHP function.
