Sign in to read
Impact	This vulnerability presents moderate-to-high real-world risk driven by multiple convergent signals. The CVSS 4.0 vector (AV:N, AC:L, PR:N, UI:N) indicates a network-accessible endpoint requiring no authentication, user interaction, or specialized complexity-a straightforward attack surface. The CVSS Environmental scores (VC:L, VI:L, VA:L) indicate confidentiality and integrity impact; the E:P tag confirms public exploit availability. Critically, the lack of vendor response after early disclosure suggests no patch timeline, leaving affected systems unpatched indefinitely. While EPSS data is not provided, the combination of unauthenticated network access, public POC, and vendor non-responsiveness elevates this beyond a theoretical risk. The absence of KEV (CISA Known Exploited Vulnerability) status does not diminish concern-public POC availability alone creates immediate abuse risk. Organizations running yudao-cloud 2026.01 or earlier should treat this as actively exploitable and prioritize immediate mitigation or isolation.
Exploit ScenarioDerived	An unauthenticated remote attacker sends a crafted HTTP request to /admin-api/system/tenant/get-by-website with SQL injection payload in the Website parameter (e.g., Website=example.com' OR '1'='1). The application fails to sanitize this input and passes it directly into a SQL query, allowing the attacker to extract sensitive data from the database (tenant records, credentials, configuration) or modify records. Public exploit code is available on GitHub (https://github.com/NarcherAlter/Security_Note/blob/main/Vulnerability_Discovery/yudaoCloudv2026.01.md), lowering the barrier to weaponization for opportunistic attackers scanning for vulnerable instances.

AnalysisAIv1 – Mar 30, 2026

Remote SQL injection in YunaiV yudao-cloud up to version 2026.01 allows unauthenticated attackers to execute arbitrary SQL queries via the Website parameter in the /admin-api/system/tenant/get-by-website endpoint. The vulnerability has a CVSS score of 6.9 with public exploit code available, enabling remote compromise of database confidentiality and integrity without authentication or user interaction. The vendor has not responded to early disclosure notification.

RemediationAI

No vendor-released patch identified at time of analysis; the vendor has not responded to early disclosure notifications. Immediate mitigation options include: (1) Upgrade to a patched version if released post-2026.01 (recommended once available); (2) Implement network-level access controls to restrict access to the /admin-api/system/tenant/get-by-website endpoint to trusted internal networks only; (3) Deploy a Web Application Firewall (WAF) with SQL injection detection rules to monitor and block malicious queries targeting the Website parameter; (4) Consider temporarily disabling the tenant management API endpoint if operationally feasible. Monitor VulDB (https://vuldb.com/vuln/354181) and the vendor's GitHub repository for patch announcements. Given vendor non-responsiveness, communities may provide security patches or forks-evaluate carefully before adopting.

Technical ContextAI · show details

The vulnerability exists in the yudao-cloud application framework, specifically in the tenant management API endpoint /admin-api/system/tenant/get-by-website. The root cause is classified as CWE-89 (SQL Injection), stemming from insufficient input validation or parameterization of the Website parameter before it is incorporated into a SQL query. The affected product (cpe:2.3:a:yunaiv:yudao-cloud:*:*:*:*:*:*:*:*) is an open-source cloud architecture framework. The flaw allows an attacker to manipulate SQL query logic by injecting malicious SQL syntax into the Website input field, potentially bypassing authentication and authorization checks within the application's database layer.
