high Tenable Cloud Security Plugin ID 441224

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - YetAnotherForum.NET (YAF.NET) is a C# ASP.NET forum. Prior to 4.0.5, Any admin OnPost… handler executes
 its side effects before the ResultFilterAttribute rewrites the response to a 302 to /Info/4. The most
 impactful abuse is /Admin/RunSql, whose OnPostRunQuery binds Editor from the POST body and passes it
 straight to IDbAccess.RunSql with no caller check, yielding arbitrary SQL execution for any low-privileged
 user. This vulnerability is fixed in 4.0.5. (CVE-2026-43937)

Solution

Update the YAFNET.Core library and its related packages to version 4.0.5 or later.
