CVE-2025-67845Public exploitNetwork attack vector

Cross-domain script execution via encoded path traversal

Published Dec 19, 2025 · Updated Dec 19, 2025

Path traversal in Mintlify Platform before 2025-11-15 allows remote authenticated users to execute script in customer domains. The /_mintlify/static/ proxy decodes path segments after tenant scoping, so encoded traversal leaves the selected CDN directory and fetches another tenant's uploaded asset. An attacker needs a tenant-controlled malicious asset; a visitor who opens the crafted URL runs it under the targeted custom domain, exposing data available to that origin.
