Remote code execution via inherited prototype traversal
Published Nov 6, 2023 · Updated Sep 4, 2024
Prototype pollution in clickbar. GmbH Dot Diver before 1.0.2 allows remote attackers to execute code through crafted object paths. The setByPath function follows inherited constructor and prototype properties while reducing a dot path, then assigns the supplied value to the resolved object. A consuming application must pass an attacker-controlled path to the library; the demonstrated path pollutes Object.prototype and can alter application behavior.
