CVE-2025-52643
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 is affected by a vulnerability where untrusted file parsing operations are not executed within a properly isolated sandbox environment. This may expose the application to potential security risks, including unintended behaviour or integrity impact when processing specially crafted files.
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 fails to execute untrusted file parsing operations within a properly isolated sandbox environment. When processing specially crafted files, this lack of isolation may allow attackers to cause unintended behavior or impact system integrity.

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, typically found in the product documentation, installation directory, or by querying the application with its version command or configuration filesAffected if The installed version is 2.0.0 or higher but lower than 2.1.2
-
Confirm the version falls within affected rangeCompare your installed version number against the vulnerable range: version >= 2.0.0 and version < 2.1.2Affected if Your version meets both conditions in the affected range
-
Determine if untrusted file parsing is performedIdentify whether your HCL AION deployment processes files from untrusted or external sources, including user-uploaded files, documents from external systems, or files from non-trusted network locationsAffected if The system processes any untrusted or externally-sourced files for parsing
-
Assess sandbox isolation configurationReview HCL AION configuration settings or documentation to determine whether file parsing operations are executed within an isolated sandbox environmentAffected if Sandbox isolation is not properly configured or is absent for file parsing operations
You are affected if your HCL AION version is between 2.0.0 and 2.1.1 inclusive and the system processes untrusted files without proper sandbox isolation for parsing operations.
Generated from the published advisory. Verify against your own configuration.
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.
dbcve · scoped2.1.2
Implement a properly isolated sandbox environment for all untrusted file parsing operations to prevent integrity impact and unintended behavior from specially crafted files.
2.1.2 or later
- Identify the current HCL AION version installed in your environment
- Review and backup all existing configurations and data
- Upgrade HCL AION to version 2.1.2 or later following HCL's official upgrade documentation
- After upgrade, verify that the sandbox isolation for file parsing operations is properly enabled
- Confirm that untrusted file parsing now executes within the isolated sandbox environment
