Updated unsafe topic detection for AI Security for Apps

WAFCloudflare · Application security

AI Security for Apps now supports an updated set of categories for detecting unsafe topics in incoming prompts.

The values available in cf.llm.prompt.unsafe_topic_categories have changed. Existing WAF custom rules remain valid, but rules that reference a removed or renamed category will no longer match that category. Review any rules that use this field and update their expressions to use the currently supported values.

For category descriptions and configuration guidance, refer to Unsafe topics.
