CVE-2021-23460Public exploitNetwork attack vector

Object prototype modification via coerced set paths

Published Jan 21, 2022 · Updated Sep 16, 2024

Prototype pollution in Camunda min-dash before 3.8.1 allows remote attackers to modify object prototypes through crafted set paths. The set function blocks a literal proto key but accepts array keys that stringify to proto and constructor paths, then writes through the inherited prototype. Exploitation requires a consuming application to pass attacker-controlled paths to set; polluted properties can alter application behavior or cause a crash.
