Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Eclipse Jersey's jersey-client (Maven org.glassfish.jersey.core:jersey-client) versions 2.45, 3.0.16 and 3.1.9 are affected by a race condition that can cause critical SSL configurations, such as mutual authentication and custom key or trust stores, to be ignored. Under certain conditions this could let a client trust an insecure server; the source gives few details on how an attacker would trigger it. Upgrade to jersey-client 2.46, 3.0.17 or 3.1.10, matching your version line.
