Machine-written summary

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

Quarkus HTTP core (io.quarkus.http:quarkus-http-core) versions before 5.3.4 incorrectly parse cookies that contain certain value-delimiting characters. An attacker who can send requests to the application can craft a cookie value to read HttpOnly cookie values or add spoofed cookies, affecting data confidentiality and integrity. Upgrade to version 5.3.4 or later.
