Summary
HCL AION has a vulnerability where the X-Content-Type-Options header was missing or insecure, allowing browsers to MIME-sniff responses. This may cause content to be interpreted as an unintended type.
Risk Assessment
An attacker could cause the browser to interpret content as a different type, potentially resulting in malicious script execution or other unintended behavior.
Recommendation
Configure the X-Content-Type-Options header to 'nosniff' for all application responses.
Other vulnerabilities in HCL AION
See all- CVE-2026-66987Medium
HCL AION has an account lockout mechanism that does not sufficiently restrict repeated failed login attempts. An attacker could make a large number of password guesses against a user account.
- CVE-2026-66986Low
HCL AION is affected by a vulnerability where user sessions did not expire after a sufficient period of inactivity. An unattended authenticated session could be used by another person with access to the same system to view information or perform actions on behalf of the user, potentially resulting in unintended behavior or security impact under certain conditions.
- CVE-2026-66984Low
HCL AION reveals internal server file system paths in certain application responses. This information could help an attacker understand the application structure and plan further attacks.
- CVE-2026-66982Low
In HCL AION, browser autocomplete was enabled on sensitive login form fields, allowing the browser to store and suggest previously entered values. A malicious user with access to the same browser or system could retrieve saved credentials.
- CVE-2026-66981Medium
HCL AION trusts the HTTP Host header value supplied in requests without validation. An attacker could manipulate this header to influence links, redirects, or responses generated by the application.
- CVE-2026-21834Low
HCL AION was missing the Content-Security-Policy (CSP) security response header in application responses. Without this header, the browser does not restrict the sources of scripts and other content, increasing exposure to cross-site scripting and content-injection attacks.
- CVE-2026-5345Low
HCL AION is affected by a missing encryption vulnerability in a second WebSocket connection defined in the GenAI web interface. The connection used the unencrypted ws:// protocol instead of an encrypted wss:// channel.
- CVE-2026-35113Medium
HCL AION is affected by a vulnerability where the Cross-Origin-Opener-Policy (COOP) header was missing or insecure, allowing cross-origin documents to share a browsing context with the application. This may enable cross-window attacks, potentially resulting in unintended behavior or security impact under certain conditions.
- CVE-2026-35112Medium
HCL AION is affected by a vulnerability where the Cross-Origin-Embedder-Policy (COEP) header was missing or insecure, so embedded cross-origin resources were not required to explicitly grant permission. This weakens cross-origin isolation, potentially resulting in unintended behavior or security impact under certain conditions.
- CVE-2026-35111Medium
HCL AION is affected by a vulnerability where the Cross-Origin-Resource-Policy (CORP) header was missing or insecure, allowing application resources to be loaded by other origins. This may expose resources to cross-origin data leakage, potentially resulting in unintended behavior or security impact under certain conditions.
