Summary
A flaw was found in Apache CXF. A remote attacker can trigger a Denial of Service (DoS) by submitting specially crafted compressed data during token processing.
Because the system decompresses incoming data without enforcing a maximum output size limit, a small payload can consume excessive heap memory. This unchecked expansion can exhaust system resources and crash the service.
Red Hat severity: Important — CVSS 7.5 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H). Weakness: CWE-409.
