CVE-2024-52810Public exploitNetwork attack vector

Service interruption via unsafe deepCopy prototype writes

Published Nov 29, 2024 · Updated Dec 3, 2024

Prototype pollution in Intlify Vue I18n 9.7.0 through 9.14.1 and 10.0.0 through 10.0.4 allows attackers to alter prototypes via crafted objects. The deepCopy function recursively assigns untrusted proto keys into ordinary destination objects, invoking the inherited prototype setter. Reachability requires a consuming application to pass attacker-controlled objects to deepCopy; resulting pollution can crash the process, while code execution additionally requires propagation into a sensitive API.
