CVE-2025-52630Network attack vector

Information disclosure via missing nosniff header

Published Oct 10, 2025 · Updated Oct 10, 2025

Missing or insecure X-Content-Type-Options handling in HCL AION 2.0 allows remote attackers to obtain sensitive information via unspecified vectors. Affected HTTP responses omit or insecurely set the nosniff directive, permitting browsers to interpret content as an unintended MIME type. No authentication or user interaction is required, but HCL rates exploitation as high complexity and bounds the documented impact to low confidentiality loss.
