26 October 2026Cloudflare Workers AI: GLM-5.3 leaked 155 answers between customers

Cloudflare reported that GLM-5.3 on Workers AI (@cf/zai-org/glm-5.3) returned data from other customers' requests in 27 answers between 9 August and 2026 September 155. Only prompts above 681,280 tokens were affected; the cause was a KV cache that was too small in the hosting configuration, not the model itself. Cloudflare found no evidence of misuse and fixed it on 9 September. If you used very long prompts containing personal data via Workers AI in that period, assess whether a data breach has occurred. source

Does GLM (Z.ai) train on my data?
The international service Z.ai runs through JINGSHENG HENGXING TECHNOLOGY PTE. LTD. (Singapore); personal data is in principle processed in Singapore. According to the data processing agreement, API content is processed in real time and not stored. GLM-5.2 is open-weight under MIT and can therefore be fully self-hosted or hosted through an EU provider.
What should I look out for with AI in building management & installations?
Keep two things in view at once. First, privacy: occupancy, badge and booking data can often be traced back to individual employees. Measure at zone or room level, not per person, and involve the works council when introducing it, a system that records staff presence falls under article 27 of the Dutch Works Councils Act (WOR) on staff monitoring systems. Second, security: an AI layer that is allowed to control your BMS becomes part of your operational technology. Never expose that connection unsecured to the internet, work with read-only access until you trust the behaviour, and record who can intervene if the control goes wrong, in care buildings, laboratories and server rooms, a wrong setpoint can cause immediate damage. If you fall under NIS2, there are explicit requirements for supplier management and incident reporting. Also agree a data processing agreement and EU hosting with every supplier, and check energy-saving claims against your own meter data rather than the brochure.
