Apache MINA vulnerable to Deserialization of Untrusted Data (CVE-2026-41635 Incomplete Fix)

The fix for CVE-2026-41635 was not applied to the 2.1.X and 2.2.X branches. Here was the original issue description: Apache MINA's AbstractIoBuffer.resolveClass contains two branches, one of them for static classes or primitive types does not check the class at all, bypassing the classname...

CVE-2026-42779

CVE-2026-42779 affects Apache MINA’s AbstractIoBuffer.resolveClass(), where one branch bypasses the classname allowlist and permits arbitrary class loading, enabling potential remote code execution via IoBuffer.getObject(). Affected are MINA 2.1.0–2.1.11 and 2.2.0–2.2.6. The issue is fixed by int...

CVE-2026-41363

OpenClaw versions 2026.2.6 through 2026.3.24 contain a path traversal vulnerability in the Feishu extension resolveUploadInput function that bypasses file-system sandbox restrictions. Attackers can exploit improper path resolution during uploadimage operations to read arbitrary files outside...
