Remote code execution via unsafe prototype writes
Published Jun 17, 2024 · Updated Aug 2, 2024
Prototype pollution in Almela obx before 0.0.4 allows remote attackers to execute arbitrary code through crafted object properties. The add and reduce paths and Object.set assign attacker-controlled proto or constructor.prototype properties without blocking writes to Object.prototype. Exploitation requires a consuming application to pass untrusted object data to an affected function, after which shared object behavior can be altered and application-context code execution can follow.
