Description

A security flaw has been discovered in YunaiV yudao-cloud up to 3.8.0. This affects the function doFilterInternal of the file JwtAuthenticationTokenFilter.java of the component Ruoyi-Vue-Pro. Performing a manipulation of the argument mock-token results in improper authentication. Remote exploitation of the attack is possible. The exploit has been released to the public and may be used for attacks. The vendor was contacted early about this disclosure but did not respond in any way.
