CVE-2026-90449

MEDIUM CVSS 4.0: 6.9 EPSS 0.20%
Updated Oct 03, 2026
Cisa
Parameter Value
CVSS 6.9 (MEDIUM)
Type CWE-306 (Missing Authentication for Critical Function)
Vendor Cisa
Public PoC No

When a particular authentication mode is configured, the reverse proxy forwards requests for a bundled third-party administrative interface directly to that interface without applying the gateway's own authentication requirement first. All access control for this administrative interface, which manages the credential store used to gate every other service in the deployment, is delegated entirely to that third-party interface's own login mechanism. Any authentication weakness in that bundled interface would compromise the credential store protecting the rest of the deployment.
