CVE-2026-21762: HCL DevOps Loop missing HTTP security headers

CVE-2026-21762 · Severity: low · CVSS 3.7 · Published 2026-07-17

Vendors: HCL Software.

Executive brief

HCL DevOps Loop is a development tool used to streamline software delivery workflows. A security issue was identified where the application fails to include standard security instructions (headers) in its web communications. This omission makes it easier for attackers to perform web-based attacks like clickjacking or cross-site scripting, potentially compromising user sessions or data integrity.

Technical details

HCL DevOps Loop version 2.0.0 is vulnerable to CWE-644 (Improper Neutralization of HTTP Headers for Scripting Syntax) due to missing security-related HTTP response headers. The absence of headers such as X-Frame-Options, X-Content-Type-Options, or Content-Security-Policy reduces the browser's ability to enforce security boundaries. An unauthenticated remote attacker can leverage this lack of defense-in-depth to facilitate client-side attacks like clickjacking or XSS. The vulnerability has a low CVSS score of 3.7 as it typically requires additional flaws to be exploited effectively. Users are advised to refer to HCL Software's security bulletin KB0132296 for remediation steps.
