CVE-2026-75627
CriticalCVSS 9.8Summary
Bastillion fails to properly validate request URI paths in its controller dispatcher, allowing unauthenticated attackers to bypass authentication filters by prefixing requests with arbitrary path segments. Attackers can access administrative controllers to read user listings, create manager accounts, and register managed systems, gaining control over SSH access to the managed fleet.
Risk Assessment
The risk includes unauthorized access to the administrative panel, which can lead to full control over SSH infrastructure and compromise the confidentiality and integrity of managed systems.
Recommendation
It is recommended to immediately update Bastillion to a patched version and implement additional URI path validation mechanisms at the server level.
