CVE-2026-59876

A flaw was found in protobufjs. The Text Format extension, responsible for compiling protobuf definitions into JavaScript functions, improperly parsed string-keyed map entries. This allowed a specially crafted map entry with the key proto to modify the prototype of the returned map object. An...

protobufjs: protobufjs: Arbitrary code execution due to unsafe expression generation from crafted protobuf descriptors

A flaw was found in protobufjs, a library used to compile protobuf definitions into JavaScript functions. A remote attacker could exploit this vulnerability by providing a crafted descriptor that includes a non-string default value for a bytes field. This could lead to the generation of an unsafe...
