Answer in brief
CVE-2026-50645 records a High severity (CVSS 7.5) vulnerability in Apache CXF: No restriction on attachment headers per message. The current sources do not mark it as known exploited. The current feed maps Apache Software Foundation/Apache CXF (generic), org.apache.cxf:cxf-core (maven), org.apache.cxf:cxf-core (maven). Check affected ranges and fixed versions before updating.
Analysis pending evidence review
HOL Guard separates source facts from reviewed analysis. See the methodology.
CVSS is 7.5. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

There is no restriction on the amount of attachment headers that a message can contain when being deserialized by Apache CXF, which can lead to uncontrolled resource consumption or a denial of service attack. Users are recommended to upgrade to versions 4.2.2 or 4.1.7 or 3.6.12, which fix this issue by imposing a maximum default of 500 attachments per message.
