Description

This security bulletin contains information about 1 vulnerability.


1) Infinite loop (CVE-ID: CVE-2026-106121)

CWE-ID: CWE-835 - Loop with Unreachable Exit Condition ('Infinite Loop')

CVSSv4: 6.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a highly privileged remote attacker to cause denial of service in RabbitMQ Java Client applications using the default JSON-RPC mapper.

The vulnerability exists due to missing end-of-input checks in JSONReader, causing infinite loops when parsing unterminated quoted strings or line comments. A highly privileged remote attacker can publish a single truncated message to an RPC request queue, exhausting heap memory or indefinitely occupying a server thread.
