Cross-request KV cache exposure in the GLM-5.3 Workers AI model (155 responses)

AI summary Cloudflare said a flaw in its Workers AI deployment of GLM-5.3 let 155 responses include data from other customers' recent requests between August 27 and September 9, 2026. The leak, reported on September 8 by Gadi Evron of Knostic, hit only prompts exceeding 681,280 tokens, and the company found no sign of deliberate exploitation. It stemmed from a KV cache pool smaller than the 1,048,576-token context window, combined with a bug in the open-source SGLang engine. After fixing both, Cloudflare restored the model on September 9 and urged operators to move to SGLang v0.5.22 or later.

Google Updates Spam Guide For Shared Pages, Generated Content & Apps

AI summary On Oct. 26, Google revised its spam guidance for hosting platforms, adding a section telling services that let users make shareable pages, interactive tools or generated content to keep them out of search by default with noindex or a robots.txt block. The guide, previously updated on Dec. 10, 2025, now also recommends verifying sites in Search Console, watching indexing and performance reports, and setting alerts when a few users produce a large portion of indexable URLs. Google's own documentation notes that a robots.txt block stops Googlebot from reading a noindex rule, and blocked URLs may still appear in the index when other sites link to them.
