Description

This security bulletin contains information about 1 vulnerability.


1) Uncontrolled Recursion (CVE-ID: CVE-2026-48712)

CWE-ID: CWE-674 - Uncontrolled Recursion

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to cause a denial of service.

The vulnerability exists due to uncontrolled recursion in google.protobuf.Any JSON conversion and generated toObject() conversion when converting decoded protobuf messages to JSON or plain objects. A remote attacker can provide a crafted protobuf binary payload with deeply nested Any values to cause a denial of service.

Exploitation requires that the application decode attacker-influenced protobuf input, that the schema include google.protobuf.Any with a resolvable type_url, and that the decoded message be converted through an affected JSON conversion path.
