No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

Builder.io Gen2 SDKs through versions 5.2.11 and 0.25.13 contain a prototype pollution vulnerability in the deep-set helper function that processes content block bindings without validation. Attackers can craft content blocks with binding keys containing __proto__, prototype, or constructor paths to pollute Object.prototype during rendering, affecting all subsequent objects created in the process including other tenants' renders.
