Updated AutoMapper from 13.0.1 to 16.1.1.

Release notes

Sourced from AutoMapper's releases.

16.1.1

What's Changed

Security

Fixed an issue where certain cyclic or self-referential object graphs could trigger uncontrolled recursion during mapping, potentially resulting in stack exhaustion and denial of service.

Applications that process untrusted or attacker-controlled object graphs through affected mapping paths may be impacted.

Users should upgrade to this release.

Security advisory: GHSA-rvv3-g6hj-g44x

Thanks to @​bluefossa for responsibly disclosing this issue.

What's Changed

Full Changelog: LuckyPennySoftware/AutoMapper@v15.1.0...v16.0.0-beta-1

This release is a beta release that introduces .NET 10 support and package signing. Signed packages means going forward packages can be validated against trusted authorities that the package has been published by Lucky Penny Software and not tampered with.

15.0.1

What's Changed

Full Changelog: LuckyPennySoftware/AutoMapper@v15.0.0...v15.0.1

This release supersedes the 15.0.0 release, reverting behavior and overloads so that the AddAutoMapper overloads separate the "scanning for maps" from the "scanning for dependencies". Unfortunately it's not really possible to combine these two together.

This also fixes a critical bug in #​4545 that does not work with .NET 4.x applications (as intended).

Because of this, the 15.0.0 will be delisted because of the breaking changes there.

15.0.0

Full Changelog: LuckyPennySoftware/AutoMapper@v14.0.0...v15.0.0

  • Added support for .NET Standard 2.0
  • Requiring license key
  • Moving from MIT license to dual commercial/OSS license

To set your license key:

services.AddAutoMapper(cfg => {
    cfg.LicenseKey = "<License key here>";
});

This also introduced a breaking change with MapperConfiguration requiring an ILoggerFactory for logging purposes:

public MapperConfiguration(MapperConfigurationExpression configurationExpression, ILoggerFactory loggerFactory)

Registering AutoMapper with services.AddAutoMapper will automatically supply this parameter. Otherwise you'll need to supply the logger factory.

You can obtain your license key at AutoMapper.io

@andrerav @stagep As far I understand, this doesn't pose a threat to mapster.

Automapper is now released under a dual license, but since we provide the source code, can we use 16.1.1 without purchasing a license or should we also change the license for benchmark to RPL-1.5?

@DocSvartz @stagep In my opinion, this "vulnerability" is a complete joke. It's a recursive mapping with max recursion depth disabled. What would anyone expect to happen? Mapster also has this "vulnerability" if you don't use any of the well-documented mechanisms that can prevent it: https://github.com/MapsterMapper/Mapster/wiki/Object-references

I guess it would cause a Map Overflow exception :)

@andrerav @stagep It looks like the security alert has disappeared. :)
