CVE-2026-93579: CWE-1035 in Red Hat Red Hat AMQ Broker 7
A vulnerability in Netty's HTTP/2 stack allows remote attackers to inject prohibited characters into HTTP/2 header field values. This occurs due to insufficient validation of header values, enabling injection of characters like NUL, Line Feed, and Carriage Return. When these manipulated headers cross from HTTP/2 to HTTP/1.1 translation boundaries, they can be exploited for request smuggling, header injection, or response splitting. The vulnerability can lead to unauthorized access or data manipulation.
AI Analysis
Technical Summary
CVE-2026-93579 describes a flaw in Netty's HTTP/2 implementation where insufficient validation of HTTP/2 header field values permits injection of prohibited characters such as NUL, Line Feed, and Carriage Return. This flaw can be exploited when headers are translated from HTTP/2 to HTTP/1.1, potentially enabling request smuggling, header injection, or response splitting attacks. These attacks may result in unauthorized access or manipulation of data.
Potential Impact
The vulnerability allows attackers to perform request smuggling, header injection, or response splitting by injecting prohibited characters into HTTP/2 headers. This can lead to unauthorized access to resources, data manipulation, or bypassing security controls. The CVSS score of 6.5 (medium severity) reflects the potential for confidentiality and integrity impacts without availability impact.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or patch information is provided in the available data. Until a patch is available, monitor vendor communications for updates.
