CVE-2026-21762: CWE-644: Improper Neutralization of HTTP Headers for Scripting Syntax in HCLSoftware DevOps Loop
HCL DevOps Loop is affected by missing HTTP security headers. Missing security headers may reduce browser protections against common web-based attacks such as clickjacking, MIME-type sniffing, and cross-site scripting.
AI Analysis
Technical Summary
CVE-2026-21762 identifies a vulnerability in HCL DevOps Loop 2.0.0 where HTTP security headers are missing. This improper neutralization of HTTP headers (CWE-644) can weaken browser defenses against attacks like clickjacking, MIME-type sniffing, and cross-site scripting. The vulnerability has a low impact on confidentiality, no impact on integrity or availability, and requires network attack vector with high attack complexity and no privileges or user interaction needed. No known exploits are reported in the wild, and no vendor remediation level or patch is currently documented.
Potential Impact
The missing HTTP security headers reduce browser-level protections, potentially increasing the risk of clickjacking, MIME-type sniffing, and cross-site scripting attacks. However, the impact is limited to confidentiality with no reported impact on integrity or availability. The overall severity is low, and no active exploitation is known.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, consider implementing recommended HTTP security headers (such as X-Frame-Options, X-Content-Type-Options, and Content-Security-Policy) via web server or proxy configurations to mitigate the risk.
