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

Questions

How safe is GLM (Z.ai) for procurement & tendering?
GLM (Z.ai) has a concrete GDPR concern. Parent company Zhipu (Beijing) is subject to Chinese data and security legislation, regardless of where the servers are located. For sensitive data, self-hosting the MIT-licensed weights is the recommended mitigation. Weigh this heavily before deploying it in procurement & tendering. There is a concrete GDPR concern, read the details on the page.
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 procurement & tendering?
Quotes, prices, contracts and submissions are commercially confidential; supplier and contact details also contain personal data. Sign a data processing agreement, ask where the data is stored (EU hosting) and which AI sub-processors are used, and get it recorded that your bids and spend data are not used to train models. Never paste confidential documents from an ongoing tender into a free chatbot. In public procurement, the Dutch Public Procurement Act and the principles of equal treatment and transparency apply: do not let AI award or exclude on its own, and explain how an assessment was reached. If you as a public body procure AI yourself, use the PIANOo guideline 'Buying or having algorithms and AI developed' and take the AI Act into account. An AI-generated submission remains your responsibility: check every commitment.
