CVE-2026-48518— MultiJuicer: Login CSRF allows attacker to force victims into their team

MultiJuicer: Login CSRF allows attacker to force victims into their team

MultiJuicer is used to run separate Juice Shop instances on a central kubernetes cluster without the need for local instances. In versions 8.0.0 through 10.0.0, the team join endpoint (POST /multi-juicer/api/teams/{team}/join) accepted requests with any Content-Type, including text/plain. Because that content type does not trigger a CORS preflight, an attacker could host a cross-site HTML form that auto-submits to the endpoint and forces a victim's browser to log in as the attacker's team. A successful, undetected attacker can cause victims to unwittingly solve Juice Shop challenges under the attacker's team identity. In a CTF context this lets the attacker inflate their team's score using other players' activity, and any sensitive data the victim enters into "their" Juice Shop ends up in the attacker's instance. The vulnerability is exploitable without any prior authentication; the victim only needs to visit a page the attacker controls while having network access to the MultiJuicer deployment. SameSite=Strict on the session cookie does not mitigate this, because the attack plants a new cookie rather than relying on an existing one. This issue was fixed in version 10.0.1.

跨站请求伪造(CSRF)

juice-shop multi-juicer 跨站请求伪造漏洞

multi-juicer是juice-shop的一款多容器管理工具。 MultiJuicer 8.0.0版本至10.0.0之前版本存在跨站请求伪造漏洞，该漏洞源于团队加入端点接受任意Content-Type请求，包括text/plain，且该类型不会触发CORS预检，可能导致攻击者托管跨站HTML表单自动提交到端点，强制受害者浏览器以攻击者团队身份登录，从而在受害者不知情的情况下以攻击者团队身份解决挑战，造成分数膨胀和数据泄露。
