Who should care

Defenders responsible for JeecgBoot installations, particularly those using versions up to 3.9.5, should assess exposure and prioritize patching. Security teams should monitor for suspicious activity related to AI prompt template modifications.

Why it matters

CVE-2026-108665 is a medium-severity vulnerability in JeecgBoot that allows authenticated users to modify AI prompt templates due to missing authorization. Defenders should prioritize patching affected installations, monitoring for suspicious activity, and implementing additional access controls.

• Potential unauthorized modification of AI prompt templates by authenticated users
• Possible overwrite of prompt text and model parameters created by administrators or other users
• Need for verification of affected versions and implementation of proper authorization checks
• Priority on patching and monitoring for suspicious activity related to AI prompt template modifications

Technical summary

The vulnerability exists in the AiragPromptsController edit handler of JeecgBoot through version 3.9.5. This handler fails to properly authorize users, allowing any authenticated user to modify AI prompt templates by sending PUT or POST requests to /airag/prompts/edit with a template id.
