CVE-2026-21764: HCL DevOps Loop insufficient input validation

CVE-2026-21764 · Severity: low · CVSS 3.1 · Published 2026-07-17

Vendors: HCL Software.

Executive brief

HCL DevOps Loop, a tool used for continuous software delivery and development workflows, is affected by a security flaw where it fails to properly filter special characters in user input. This could allow an attacker with existing low-level access to cause the application to behave in unexpected ways. While the risk is considered low, it could potentially lead to minor data exposure or operational inconsistencies within the development environment.

Technical details

HCL DevOps Loop version 2.0.0 is vulnerable to improper input validation (CWE-754). The application fails to adequately sanitize or restrict special characters in certain input fields, which can lead to unintended application logic execution or behavior. Exploitation requires network access and low-level authenticated privileges (PR:L), and is further mitigated by high attack complexity (AC:H). According to the vendor, an exploit could result in a limited loss of confidentiality, though integrity and availability are not directly impacted. Users are advised to refer to HCL advisory KB0132296 for remediation steps.
