Detailsinfo

A vulnerability was found in LuckyPennySoftware AutoMapper up to 15.1.3/16.2.x. It has been rated as problematic. Affected by this issue is some unknown functionality. The manipulation with an unknown input leads to a stack-based overflow vulnerability. Using CWE to declare the problem leads to CWE-121. The product writes past the end of a buffer that was allocated on the stack. Impacted is availability. CVE summarizes:

AutoMapper is a convention-based object-object mapper in .NET. Prior to 15.1.4 and from 16.0.0 until 16.3.0, AutoMapper increments type depth only after creating the destination, so recursive mapping performed through constructor parameters occurs before MaxDepth is counted. Destinations built through positional records or other constructors, and recursive ConstructUsing mappings that call context.Mapper, can therefore bypass explicit MaxDepth values and the default limit of 64. Deep attacker-influenced input can throw an uncatchable StackOverflowException and terminate the process. This issue is fixed in versions 15.1.4 and 16.3.0.

The advisory is shared for download at github.com. This vulnerability is handled as CVE-2026-128082 since 11/12/2026. The exploitation is known to be easy. The attack may be launched remotely. No form of authentication is required for exploitation. There are neither technical details nor an exploit publicly available.

Upgrading to version 15.1.4 or 16.3.0 eliminates this vulnerability.
