CVE-2025-52645
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 model packaging and distribution mechanisms may not include sufficient authenticity verification. This may allow the possibility of unverified or modified model artifacts being used, potentially leading to integrity concerns or unintended behaviour.
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 has insufficient authenticity verification in its model packaging and distribution mechanisms, allowing potentially tampered or unverified model artifacts to be loaded and executed, which could lead to integrity compromise or unexpected behavior.

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 versionRun the command to retrieve the HCL AION version (commonly via 'aion --version', 'aion -v', or checking the product's 'About' dialog in the management console)Affected if The installed version is >= 2.0.0 and < 2.1.2
-
Locate model configuration filesSearch for configuration files related to model loading or artifact management (commonly in the installation directory or config folder, with names like 'model.conf', 'aion.config', or similar)Affected if No cryptographic verification or integrity checking settings are defined for model artifacts
-
Inspect model loading behaviorReview logs or trace settings for model loading operations to determine if models are being loaded without integrity verificationAffected if Logs show models loading from paths or sources without signature or hash validation
-
Check model artifact storage locationsExamine directories where model files are stored to identify if they include bundled or embedded artifacts without external verificationAffected if Model artifacts are loaded from locations that lack signed manifest or certificate-based verification
-
Review authentication policiesInspect any policy or security configuration files that control model artifact acceptance and loadingAffected if No policy enforces authenticity verification (such as digital signature validation) before model execution
The environment is affected if HCL AION version is 2.0.0 through 2.1.1 and model artifacts can be loaded without cryptographic integrity or authenticity verification.

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 cryptographic signing and verification of model artifacts throughout the packaging and distribution lifecycle to ensure only authenticated, untampered models are deployed.
Aion 2.1.2
- Review the HCL Aion 2.1.2 release notes and migration documentation on support.hcl-software.com for any known compatibility or migration requirements
- Plan and schedule the upgrade during a maintenance window
- Backup all existing Aion configurations, models, and data
- Upgrade Aion from the current version (>=2.0.0, <2.1.2) to version 2.1.2
- After upgrade, verify that model packaging and distribution mechanisms now include proper authenticity verification
- Test critical model workflows to confirm integrity checks are functioning as expected
- Monitor system logs for any authenticity verification failures or warnings
