Fedify has an LD-Signature Bypass via JSON-LD Named-Graph Restructuring

Summary An attacker can make use of JSON-LD features to restructure a JSON-LD document that would change how Fedify interprets it without changing its Linked Data Signature, allowing them to alter a third-party signed activity they have received. Details The vulnerability essentially boils down t...
