CyberRota Analysis
AI-GeneratedWhen OAuth authentication is enabled, the Temporal UI Server can issue access-token and refresh-token cookies without the Secure attribute due to improper handling of TLS termination at a reverse proxy. This vulnerability could allow an attacker to exploit a live credential if they can manipulate traffic to the UI hostname and serve it over HTTP, potentially leading to unauthorized access within the victim's permissions. Organizations using the affected configuration should prioritize remediation to mitigate the risk of credential exposure.

Original NVD Description
When OAuth authentication is enabled and browser-facing TLS terminates at a reverse proxy that forwards the callback to Temporal UI Server over HTTP, affected versions derive authentication-cookie Secure attributes from the proxy-to-server connection. Temporal UI Server can therefore issue access-token cookies, and refresh-token cookies when provided by the identity provider, without Secure even though the browser completed login over HTTPS. A victim who visits attacker-controlled content while a credential remains live may expose that credential only if the attacker can also steer traffic for the UI hostname, prevent the browser's HTTPS connection from succeeding, serve the hostname over HTTP, and read a later same-site plaintext request. A malicious website alone cannot read the cookie, and passive observation of a successful TLS connection is insufficient. Effective HSTS, a blocking HTTPS-only warning, or TLS re-encryption between the proxy and Temporal UI Server prevents the demonstrated disclosure path. A recovered credential may be replayed within the victim's assigned permissions. Refresh-token replay additionally depends on the identity provider's issuance, expiry, rotation, and reuse-detection behavior.
