CVE-2024-30564Public exploitNetwork attack vector

Remote code execution via recursive prototype pollution

Published Apr 18, 2024 · Updated Aug 22, 2024

Prototype pollution in NORA Firebase Common 1.0.41 through 1.12.2 allows remote attackers to execute arbitrary code via crafted state data. updateStateInternal recursively copies enumerable updateState keys into the destination without rejecting proto, constructor, or prototype, allowing Object.prototype modification. The published proof of concept establishes process-wide prototype pollution, but it does not demonstrate the claimed arbitrary code execution consequence.
