Prototype pollution via unvalidated special property paths
Published Jun 17, 2024 · Updated Aug 2, 2024
Prototype pollution in ApPHP Object Resolver before 3.1.1 allows attackers to alter Object.prototype via crafted property paths. The setNestedProperty function follows dot-separated keys and assigns through proto, constructor, or prototype without rejecting these prototype-reaching segments. Exploitation requires a consuming application to pass an attacker-controlled path and a user to trigger that code path; inherited properties can then corrupt application logic across unrelated objects.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
