CVE-2025-63402
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 · uneditedAn issue in HCL Technologies Limited HCLTech GRAGON before v.7.6.0 allows a remote attacker to execute arbitrary code via APIs do not enforcing limits on the number or size of requests
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 confidenceHCLTech GRAGON before version 7.6.0 contains APIs that lack proper rate limiting and request size constraints, allowing remote attackers to send unlimited or oversized requests that can lead to arbitrary code execution.
Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

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.
-
Confirm HCLTech GRAGON installationLocate the HCLTech GRAGON (also referred to as HCL Dragon) installation on the system. Check common installation directories or use system inventory tools to identify if the product is present.Affected if The product is not installed or cannot be located.
-
Identify installed versionRetrieve the version of HCLTech GRAGON installed. Use product-specific commands, check version files in the installation directory, or consult the product's built-in version information function.Affected if Unable to determine the installed version.
-
Compare version to affected rangeCompare the identified version against the affected range: versions prior to 7.6.0. Ensure you capture the full version string including any patch or build numbers.Affected if The installed version is lower than 7.6.0 (for example, 7.5.x, 7.4.x, or earlier).
-
Assess API exposureDetermine if the GRAGON API endpoints are network-accessible or exposed to untrusted users. Check network configurations, firewall rules, and API service status.Affected if API endpoints are publicly accessible and the version is below 7.6.0.
A user is affected if HCLTech GRAGON version is installed and that version is below 7.6.0, particularly if API endpoints are network-accessible.

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 · scoped7.6.0
Upgrade HCLTech GRAGON to version 7.6.0 or later which implements proper request limits on APIs; additionally, consider implementing WAF rules as a compensating control until the upgrade is completed.
Dragon version 7.6.0
- Identify the current installed version of HCLTech Dragon
- Backup all current data and configurations
- Download HCLTech Dragon version 7.6.0 from the official HCL Technologies portal or vendor repository
- Review the 7.6.0 release notes for any specific upgrade prerequisites or procedures
- Execute the upgrade process according to HCL's official upgrade documentation
- Verify the upgrade was successful by checking the version number
- Test that API endpoints now enforce appropriate request limits
