CVE-2025-52659
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedHCL AION version 2 is affected by a Cacheable HTTP Response vulnerability. This may lead to unintended storage of sensitive or dynamic content, potentially resulting in unauthorized access or information disclosure.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceHCL AION version 2 fails to set proper HTTP cache-control headers, allowing sensitive or dynamic responses to be stored in intermediate caches (proxies, CDNs, browsers). An attacker with access to these caches could retrieve cached sensitive data.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify installed HCL AION versionLocate and read the version information for your HCL AION installation (check installation directory, version file, or product metadata)Affected if Your installed version is exactly 2.0.0
-
Inspect HTTP response headers for cache-control directivesSend HTTP requests to your HCL AION endpoints and examine the response headers, specifically looking for cache-control header presence and valueAffected if The HTTP responses lack cache-control headers or contain values that allow caching (e.g., missing no-store, no-cache, or private directives)
-
Verify sensitive endpoints for caching vulnerabilityTest dynamic or sensitive endpoints (such as authentication, user data, or administrative interfaces) by making repeated requests and checking if responses can be cached by intermediariesAffected if Sensitive endpoints return responses that could be stored in intermediate caches (proxies, CDNs, browsers)
You are affected if you are running HCL AION version 2.0.0 and your HTTP responses lack proper cache-control headers to prevent caching of sensitive data

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataConfigure HTTP responses to use appropriate cache-control directives (e.g., no-store, no-cache, private) for sensitive endpoints to prevent caching of dynamic content.
