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 social domain & youth care?
GLM (Z.ai) has a concrete GDPR concern. Parent company Zhipu (Beijing) is subject to Chinese data and security legislation, wherever the servers are located.

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 watch out for with AI in social domain & youth care?
In the social domain this involves special category personal data (health, debts, family situation, sometimes of children). Never use a free chatbot for conversations or files. Conclude a data processing agreement, require processing within the EU and no training on your data, ask which language models and sub-processors sit behind it, and carry out a DPIA. Ask the resident for consent before you record a conversation, and explain how long the recording and text are kept. Do not let AI itself judge whether someone is entitled to a provision or benefit: the EU AI Act classes systems that determine access to public services as high-risk, and the childcare benefits scandal shows what goes wrong without human checking. Register the application in the Algorithm Register and check every report before it goes into the file.
