## What is CVE-2026-7710?

CVE-2026-7710 is a medium-severity authentication bypass vulnerability in YunaiV yudao-cloud, published on 3 May 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official 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. It is suggested to update the configuration settings. The vendor explains: "[I]t remains an explicit development feature. Production deployments must disable mock-enable; changing the mock secret alone does not disable it. We added deployment guidance, not an authentication-code patch."

Weakness: CWE-287 (Improper Authentication)
