CVE-2024-36583Public exploitNetwork attack vector

Arbitrary code execution via unsafe property paths

Published Jun 17, 2024 · Updated Aug 2, 2024

Prototype pollution in Byondreal Accessor 1.0.0 and earlier allows remote attackers to execute arbitrary code through crafted property paths. The setter accepts paths containing proto or constructor.prototype and assigns supplied values into Object.prototype without blocking those special keys. An application must pass attacker-controlled paths and values to the library; process-wide property injection requires a suitable downstream gadget to reach code execution.
