CVE-2025-47886: 
Java vulnerability analysis and mitigation

A cross-site request forgery (CSRF) vulnerability has been identified in Jenkins Cadence vManager Plugin versions 4.0.1-286.v9e25a740ba_48 and earlier. The vulnerability was discovered by Vincent Lardet and was assigned CVE-2025-47886. This security flaw affects the form validation methods in the plugin, which fail to require POST requests (Jenkins Advisory).

The vulnerability stems from form validation methods that do not require POST requests, creating a CSRF vulnerability. The issue is compounded by missing permission checks in methods implementing form validation. The severity is rated as Medium with a CVSS 3.1 base score of 4.3 (MEDIUM) and vector string CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N (NVD, Wiz).

When exploited, this vulnerability allows attackers with Overall/Read permission to connect to an attacker-specified URL using attacker-specified username and password credentials. This could potentially lead to unauthorized access to resources and compromise of connected systems (Jenkins Advisory).

The vulnerability has been fixed in Cadence vManager Plugin version 4.0.1-288.v8804beaacb7f. The updated version implements proper POST request requirements and adds Item/Configure permission checks for the affected form validation method. Users are strongly advised to upgrade to this version to mitigate the vulnerability (Jenkins Advisory).

The vulnerability has been acknowledged by the Jenkins security team and was reported by Vincent Lardet. The Jenkins project has coordinated the disclosure and patching of this vulnerability as part of their regular security advisory process (Security Online).
