The AccessLogFilter class in Jira before version 8.4.0 allows remote anonymous attackers to learn details about other users, including their username, via an information expose through caching vulnerability when Jira is configured with a reverse Proxy and or a load balancer with caching or a CDN.
The code uses a cache that contains sensitive information, but the cache can be read by an actor outside of the intended control sphere.
