CVE-2026-7710
Published: 04 May 2026
Summary
CVE-2026-7710 is a medium-severity Improper Authentication (CWE-287) vulnerability. Its CVSS base score is 5.5 (Medium).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 28.1th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified are NIST 800-53 AC-3 (Access Enforcement) and IA-2 (Identification and Authentication (Organizational Users)).
Deeper analysis
CVE-2026-7710 is an improper authentication vulnerability (CWE-287) in YunaiV yudao-cloud versions up to 3.8.0. It affects the doFilterInternal function in the JwtAuthenticationTokenFilter.java file within the Ruoyi-Vue-Pro component. The flaw arises from manipulation of the mock-token argument, enabling attackers to bypass authentication mechanisms.
The vulnerability is remotely exploitable over the network with low attack complexity and no required privileges or user interaction (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L, score 7.3). Any unauthenticated remote attacker can perform the manipulation to achieve improper authentication, resulting in low-level impacts to confidentiality, integrity, and availability.
Advisories from VulDB and a GitHub issue note that the exploit has been publicly released and may be used in attacks. The vendor was contacted early about the disclosure but did not respond, and no patches or specific mitigations are detailed in the available references.

Mitigating Controls
Mitigating Controls (NIST 800-53 r5) AI
AC-3 requires the system to enforce approved authorizations for access, directly addressing the failure of the JwtAuthenticationTokenFilter to prevent authentication bypass via mock-token manipulation.
IA-2 mandates unique identification and authentication of users, countering the improper authentication vulnerability that allows unauthenticated remote attackers to bypass JWT mechanisms.
SI-10 requires validation and sanitization of information inputs, mitigating manipulation of the mock-token argument that leads to authentication bypass in the filter.
