CVE-2026-105857
In @payloadcms/plugin-form-builder versions before 3.90.0 and canary versions before 4.0.0-canary.34, an attacker can craft a form submission that executes code remotely on the server.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.43%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
