CVE-2026-4096: CWE-644 Improper Neutralization of HTTP Headers for Scripting Syntax in IBM DevOps Plan
IBM DevOps Plan 3.0.0 through 3.0.6 is vulnerable to HTTP header injection, caused by improper validation of input by the HOST headers. This could allow an attacker to conduct various attacks against the vulnerable system, including cross-site scripting, cache poisoning or session hijacking
AI Analysis
Technical Summary
CVE-2026-4096 is an HTTP header injection vulnerability in IBM DevOps Plan 3.0.0 through 3.0.6 caused by improper neutralization of HTTP headers for scripting syntax (CWE-644). Specifically, the product fails to properly validate input from HOST headers, which can be exploited to perform attacks including cross-site scripting, cache poisoning, and session hijacking. The CVSS v3.1 base score is 6.5, indicating a medium severity. There is no vendor advisory or patch available at this time, and the vulnerability is not known to be exploited in the wild.
Potential Impact
An attacker can exploit improper validation of HOST headers to inject malicious HTTP headers, potentially leading to cross-site scripting, cache poisoning, or session hijacking. This compromises confidentiality and integrity of user sessions and data within the affected IBM DevOps Plan environment. Availability is not impacted according to the CVSS vector.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, users should consider implementing input validation controls on HOST headers at network or application layers if feasible. Monitor IBM advisories for updates on patches or official mitigations.
