CVE-2026-44292 - protobufjs: Prototype injection in generated message constructors
CVE ID :CVE-2026-44292
Published : May 13, 2026, 4:16 p.m. | 50 minutes ago
Description :protobufjs compiles protobuf definitions into JavaScript (JS) functions. Prior to 7.5.6 and 8.0.2, protobufjs generated message constructors copied enumerable properties from a provided properties object without filtering the __proto__ key. If an application constructed a message from an attacker-controlled plain object, an own enumerable __proto__ property could alter the prototype of that individual message instance. This vulnerability is fixed in 7.5.6 and 8.0.2.
Severity: 5.3 | MEDIUM
