Summary

JeecgBoot through 3.9.5 contains a missing authorization vulnerability (CWE-862) in the SystemApiController updateAvatar handler. Any authenticated user can send PUT requests with a target user id and an arbitrary value, such as an attacker-controlled image URL, to change other users' avatars, including those of administrators. CVSS 4.0 scores it 5.3 (MEDIUM). A proof of concept is published, but CISA has not added it to KEV.
