AI-suggested

Users should upgrade to Mina2 version 2.2.8 or later in the 2.2.X branch where the fix is fully applied. Versions in the 2.0.X and 2.1.X branches, including 2.0.29, 2.1.13, and later releases such as 2.0.30 and 2.1.14, remain vulnerable and should not be considered fixed. If upgrading to the 2.2.X branch is not feasible, users should consider other compensating controls or isolate vulnerable versions until a proper fix is available. Patch status is confirmed for 2.2.8 and later in the 2.2.X branch only.

Description

CVE-2026-94301 is a critical vulnerability in the Mina2 library related to an incomplete fix for CVE-2026-47065. The vulnerability involves a bypass of the acceptMatchers filter due to the resolveProxyClass() method not being overridden in certain maintenance branches. Although the fix was fully applied in the 2.2.X branch (starting with version 2.2.8), the 2.0.X and 2.1.X branches remain vulnerable despite version numbers indicating a fix. This allows an attacker to bypass allow-list filtering, potentially leading to full compromise with network-level attack vector and no required privileges or user interaction.
