CVE-2025-52624
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 · uneditedA vulnerability Bypass of the script allowlist configuration in HCL AION. An incorrectly configured Content-Security-Policy header may allow unauthorized scripts to execute, increasing the risk of cross-site scripting and other injection-based attacks.This issue affects AION: 2.0.
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 2.0 has a Content-Security-Policy bypass vulnerability where the script allowlist is incorrectly configured. This misconfiguration permits unauthorized scripts to execute, enabling cross-site scripting (XSS) and injection attacks against users of the application.

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.
-
Verify HCL AION versionCheck the installed version of HCL AION by reviewing the application documentation, installation directory, or version information accessible through the product interface or system inventory tools. Compare against version 2.0.0.Affected if The installed version is exactly 2.0.0 (the affected version).
-
Inspect Content-Security-Policy headerCapture HTTP responses from the HCL AION 2.0.0 application using browser developer tools (Network tab), curl, or a proxy tool. Examine the Content-Security-Policy header in the response headers.Affected if The CSP header is present but the script-src directive contains overly permissive settings such as 'unsafe-inline', wildcard sources (*), or untrusted third-party domains.
-
Review script allowlist configurationAnalyze the script-src directive value within the CSP header. Identify whether the allowlist permits scripts from sources that should not be trusted, such as unspecified domains, self-referencing issues, or bypass-prone configurations.Affected if The script-src allowlist permits unauthorized or untrusted script sources that could enable XSS or injection attacks.
-
Test for CSP bypass potentialIf CSP is configured, attempt to identify whether the current allowlist configuration permits inline scripts or external scripts from non-allowlisted domains by reviewing the policy rules present in the header.Affected if The CSP configuration allows scripts from sources not explicitly trusted by the organization, indicating the bypass vulnerability exists.
If the installed version is HCL AION 2.0.0 and the Content-Security-Policy header's script-src directive contains permissive or misconfigured allowlist settings, the environment is affected by this CVE.

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 dataReview and correctly configure the Content-Security-Policy header to properly enforce the script allowlist, ensuring only trusted sources are permitted to execute scripts.
