Information disclosure via pooled WebSocket object double return
Published May 13, 2022 · Updated Aug 3, 2024
Information disclosure in Apache Tomcat 8.5.0 through 8.5.75 and 9.0.0.M1 through 9.0.20 allows remote attackers to receive another user's data. The WebSocket send path continues using a closed socket, and error handling can return the same pooled object twice, enabling concurrent reuse by later connections. Triggering the race requires a web application to send a WebSocket message as its connection closes; a mix-up can disclose response data or cause connection errors.
