CVE-2026-59306

Spring Cloud Stream versions 4.2.0 to 5.0.2 are vulnerable to deserialization of untrusted types, which could allow an attacker to execute arbitrary code if they can manipulate the input data. Although the severity is rated low, organizations using these specific versions should prioritize patching to mitigate potential exploitation risks, especially if they handle sensitive data or are exposed to untrusted sources.
