CVE-2026-21833

HCL AION is affected by a vulnerability where indirect prompt injection can lead to HTML injection in rendered output. Injected markup may be displayed to users, potentially resulting in unintended behavior or security impact under certain conditions.

HCL AION is affected by a vulnerability where JavaScript responses containing data could be referenced by external pages, potentially allowing sensitive information to be captured by an attacker-controlled page (JavaScript hijacking) under certain conditions.

HCL AION is affected by a vulnerability where certain input fields do not enforce sufficient server-side input validation. Unexpected or crafted input may be accepted by the application, potentially resulting in unintended behavior or security impact under certain conditions.

HCL AION is affected by a vulnerability where certain endpoints lack sufficient anti-automation controls. Automated or scripted requests may be submitted without adequate rate limiting or challenge mechanisms, potentially resulting in unintended behavior or security impact under certain conditions.

HCL AION is affected by a vulnerability where the shared storage used by product components is architected without sufficient access separation. Processes sharing the storage may be able to access or modify files beyond their intended scope, potentially resulting in unintended behavior or security impact under certain conditions.

HCL AION is affected by a vulnerability where sensitive information may be included in URL parameters. Passing sensitive data in URLs may expose it through browser history, logs, or intermediary systems, potentially leading to unintended information disclosure under certain conditions.

HCL AION is affected by a vulnerability where certain security-related HTTP response headers are not properly configured. Absence of these headers may reduce the effectiveness of browser-based security controls.

HCL AION is affected by a vulnerability where adequate protections against brute-force attempts are not enforced. This may allow repeated authentication attempts, potentially leading to unauthorized access or account compromise under certain conditions.

HCL AION is affected by a vulnerability where basic authorization tokens are used for authentication. Use of basic authorization mechanisms may expose credentials to potential interception or misuse, especially if not combined with secure transmission practices.

HCL AION is affected by a vulnerability where backend service details may be transmitted over insecure HTTP channels. This may expose sensitive information to potential interception or unauthorized access during transmission under certain conditions.
