The Static Asset API in Mintlify Platform is susceptible to a cross-tenant asset injection issue. This allows remote attackers to inject arbitrary web script or HTML through manipulation of the `subdomain` parameter. Specifically, assets belonging to one tenant can be served on another tenant's documentation site.

A Server-Side Template Injection (SSTI) flaw exists in the MDX Rendering Engine of Mintlify Platform. This issue allows remote attackers to execute arbitrary code through inline JSX expressions within an MDX file. The vulnerability is related to the processing of MDX files and the rendering of JSX expressions. SSTI occurs when user-supplied input is incorporated into a server-side template without proper sanitization, allowing an attacker to inject malicious code that is then executed by the server.

A directory traversal issue exists in the Static Asset Proxy Endpoint. This allows remote attackers to inject arbitrary web script or HTML through a specially crafted URL containing path traversal sequences. The endpoint vulnerable to this issue is the `/static` asset proxy endpoint. The vulnerability involves manipulating the URL to access files outside the intended directory.

The Deployment Infrastructure in Mintlify Platform before 2025-11-15 allows attackers to bypass security patches and execute downgrade attacks. This is possible through predictable deployment identifiers on the Vercel preview domain. An attacker can identify the URL structure of a previous deployment containing unpatched vulnerabilities and force the application to load the vulnerable version by directly accessing the specific git-ref or deployment-id subdomain.
