Cloudflare disclosed a cross-request key-value (KV) cache exposure affecting the GLM-5.3 model running on its Workers AI platform, impacting 155 responses (Cloudflare blog, October 26). The incident highlights emerging security risks in multi-tenant AI inference infrastructure, where cached data from one user's request could potentially leak into another's.
This is a distinct security incident related to, but separate from, GLM-5.3 as a model generally.
