• CVE-2026-50633 with a CVSS score of 8.1 – This JNDI injection vulnerability can be exploited by manipulating the JCA deployment descriptor and altering runtime activation parameters, allowing for unauthorized code execution.
• CVE-2026-50634 with a CVSS score of 6.5 – This metadata validation issue can be exploited by trusting metadata from an unvalidated first signature entry, bypassing crucial application assumptions and verifying protected HTTP-header metadata.
• CVE-2026-50628 – This vulnerability introduces an inverted IP binding check error, creating an inverse security check.
• CVE-2026-49875 – This XML External Entity injection vulnerability can be exploited by constructing a SAXParserFactory without necessary JAXP hardening configurations, enabling out-of-band external entity resolution.
The overall risk and urgency of these vulnerabilities are high, as they can be exploited to compromise enterprise systems and extract sensitive data. If exploited, these vulnerabilities can lead to severe business consequences, including data breaches and system compromises, highlighting the need for immediate attention and action to secure affected systems.
RECOMMENDATION:
We recommend you to update Apache CXF to version 4.2.2 or 4.1.7.
