CVE-2026-351134.8 MÉD—
———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.1hCVE-2026-351124.2 MÉD—
———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.1hCVE-2026-351114.8 MÉD—
———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.1hCVE-2026-351153.7 BAI—
———HCL AION is affected by a vulnerability where the HTTP Strict-Transport-Security (HSTS) header was missing or insecurely configured, so browsers were not instructed to always use HTTPS. This may allow connections to be downgraded or intercepted, potentially resulting in unintended behavior or security impact under certain conditions.2hCVE-2026-351143.7 BAI—
———HCL AION is affected by 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, potentially resulting in unintended behavior or security impact under certain conditions.2hCVE-2026-1204155.9 MÉD—
———undici is an HTTP client for Node.js. In versions 7.0.0 through 7.30.1 and 8.0.0 through 8.12.3, the redirect interceptor strips sensitive headers such as Authorization, Cookie, Proxy-Authorization, and Host when a request is redirected to a different origin, but when request headers are supplied as an array of name and value tuples (a valid documented input, for example from Object.entries), the redirect handler misreads them as a flat list so the header names never match and the sensitive headers are not removed. If a header-normalizing interceptor such as cache or deduplicate is composed outside the redirect interceptor, it then serializes the retained headers onto the cross-origin request, disclosing the caller's origin-bound credentials to the unrelated redirect destination. This is a representation-dependent bypass of the cross-origin header stripping added in CVE-2024-30260. The issue is fixed in undici 7.30.2 and 8.12.4, and users should upgrade to one of those versions or later. As a workaround, supply request headers as a plain object or a flat name and value array rather than an array of tuples, or compose the redirect interceptor outside the normalizing interceptor.5h
