Preliminary research
Transformers: Dark Side of the Type — Weaponizing the Conversion Layer
AI-collected research leads through 6 October 2026, including bounded month-by-month reviews of selected social and community sources from January through September. Unranked, incomplete, not community-vetted, and subject to change.
No serializer is needed for object injection: any conversion that resolves a type named in input and builds it is a sink. ResXFileRef's converter takes filename;typename;encoding, opens a UNC path and constructs ResourceSet, reaching BinaryFormatter; ImageSourceConverter turns any string into a fetched URI; ObjectDataProvider's setters reach InvokeMember. SharePoint CVE-2020-1460 and CVE-2026-47294 chain it, the latter smuggling a type as a generic argument past SafeControl.
