CVE-2024-38990Public exploitNetwork attack vector

Code execution via mergeDeep prototype pollution

Published Jul 1, 2024 · Updated Aug 2, 2024

Prototype pollution in Tada5hi sp-common 0.5.4 allows remote authenticated users to alter inherited object properties via mergeDeep. The mergeDeep function accepts a crafted proto key and writes its properties into Object.prototype without rejecting the magic property. An application must pass attacker-influenced data to mergeDeep; code execution, cross-site scripting, or a service crash requires a suitable gadget.
