Jenkins Gitee Plugin CVE-2026-57292

Exploitation requires two prerequisites to be satisfied simultaneously: first, the attacker must have already obtained one or more valid Jenkins credential IDs through a separate method (enumeration, information disclosure, or insider access) - this is not provided by the CSRF flaw itself; second, an authenticated Jenkins user with at least low-privileged access (PR:L per CVSS) must be induced to visit an attacker-controlled web page or click a crafted link while their Jenkins session is active. The Jenkins Gitee Plugin must be installed and in use. Exploitation is not automatable per the SSVC assessment. The requirement for pre-obtained credential IDs is the key limiting factor that prevents this from being a trivially exploitable standalone vulnerability.

The CVSS 5.4 Medium score reflects AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N - however, the UI:N assignment is inconsistent with the CSRF attack class, which by definition requires victim interaction (the victim's authenticated browser must submit the forged request). This likely overstates exploitability. The SSVC assessment independently corroborates a lower practical risk: exploitation status is none, the attack is not automatable (Automatable: no), and technical impact is only partial. The additional prerequisite of needing credential IDs obtained through another method further narrows the viable attacker population. This is not a standalone critical issue; it functions as a component in a multi-step attack chain and should be prioritized behind vulnerabilities with confirmed exploitation or broader access impact.

An attacker who has enumerated Jenkins credential IDs - for example, through a separate information-disclosure vulnerability or insider knowledge - crafts a malicious HTML page containing a hidden form that auto-submits a forged Gitee Plugin connection-test request. When an authenticated Jenkins user visits the page, their browser submits the request to Jenkins, which initiates an outbound connection to an attacker-controlled server using the specified credential IDs, potentially exposing the credential material to the attacker's server logs. No public exploit code is identified at time of analysis.
