CVE-2025-27925
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 · uneditedNintex Automation 5.6 and 5.7 before 5.8 has insecure deserialization of user input.
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 · high confidenceNintex Automation versions 5.6 and 5.7 before version 5.8 contain an insecure deserialization vulnerability where user-supplied data is deserialized without proper validation, potentially allowing remote 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.
-
Identify installed Nintex Automation versionAccess the Nintex Automation admin console or check the product's About/Version information page. This is typically found under Help > About or in the system administration settings. Alternatively, check any installation manifests or license files that may contain the version number.Affected if The installed version is 5.6.x or 5.7.x
-
Confirm version falls within affected rangeCompare your identified version against the vulnerable range: versions 5.6.0 through 5.7.x (any minor version) are affected. Version 5.8 or later is not vulnerable.Affected if Version is greater than or equal to 5.6.0 and less than 5.8.0
-
Verify product is exposed to networkDetermine if the Nintex Automation web interface is accessible from the network or internet. Check firewall rules, load balancer configurations, or IIS/Apache bindings that expose the application.Affected if The Nintex Automation interface is network-accessible (especially unauthenticated or weakly authenticated access increases exposure)
You are affected if Nintex Automation version 5.6.x or 5.7.x is installed and the product interface is network-accessible.
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 · scoped5.8
Upgrade Nintex Automation to version 5.8 or later to remediate this vulnerability. If immediate patching is not possible, network segmentation and input validation at perimeter layers may provide temporary risk reduction.
5.8
- Back up the current Nintex Automation installation and database before beginning any upgrade process
- Review the official Nintex upgrade documentation at help.nintex.com for version 5.8 to understand prerequisites and requirements
- Download Nintex Automation version 5.8 from the official Nintex portal or distribution channel
- Execute the upgrade following the documented upgrade procedure for your deployment model (cloud-hosted or on-premises)
- After upgrade completion, verify the Nintex Automation services are running correctly
- Confirm the version number displays as 5.8 in the Nintex Administration interface
