Machine-written summary

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

Quarkus REST (io.quarkus:quarkus-rest) and quarkus-rest-deployment, versions from 3.9.0.CR1 up to but not including 3.15.3.1, from 3.16.0.CR1 up to but not including 3.18.2, and below 3.8.6.1, are affected. REST endpoints that use field injection without a CDI scope can leak request parameters between concurrent requests, which lets an attacker manipulate request data, impersonate users, or access sensitive information. Upgrade to 3.8.6.1, 3.15.3.1, 3.18.2 or later in the fixed line for your version. The source gives few details about the attack conditions.
