CVE-2026-41635
CriticalSummary
W metodzie AbstractIoBuffer.resolveClass() w Apache MINA występuje luka, która pozwala na pominięcie listy dozwolonych nazw klas dla statycznych klas lub typów prymitywnych, co umożliwia wykonanie dowolnego kodu. Problem został rozwiązany w wersjach Apache MINA 2.0.28, 2.1.11 i 2.2.6 poprzez wcześniejsze zastosowanie listy dozwolonych nazw klas.
Risk Assessment
Organizacje korzystające z podatnych wersji Apache MINA mogą być narażone na wykonanie złośliwego kodu, co może prowadzić do poważnych naruszeń bezpieczeństwa i utraty danych.
Recommendation
Zaleca się aktualizację do najnowszych wersji Apache MINA, aby usunąć tę podatność i zabezpieczyć aplikacje korzystające z IoBuffer.getObject().

Hazelcast prior to 5.4.5, 5.5.10, and 5.6.1 contains improper validation of data supplied by a malicious client able to connect to a cluster, allowing arbitrary reads from a cluster member's Java heap, off-heap data, and JVM process address space. The same flaw can crash cluster members and, in some Hazelcast Enterprise Edition configurations, corrupt memory with possible arbitrary code execution. This issue is fixed in versions 5.4.5, 5.5.10, 5.6.1, and 5.7.0.
- CVE-2026-107722Critical
fast-jwt from 6.2.0 until 6.3.0 can misclassify RSA public-key text as an HMAC secret when the key has non-whitespace content before its PEM header. In src/crypto.js, performDetectPublicKeyAlgorithms trims whitespace but publicKeyPemMatcher remains start-anchored, so comments, control characters, zero-width characters, or wrapper text can prevent PEM detection and reach the HMAC fallback. An attacker who knows the public key bytes can sign arbitrary HS256 claims with that public material when HS256 is inferred or allowed, resulting in authentication or authorization bypass. An asymmetric-only algorithm allowlist prevents the attack. This issue is fixed in version 6.3.0.
Original NVD description (English source)
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 allowlist and allowing arbitrary code to be executed. The fix checks if the class is present in the accepted class filter before calling Class.forName(). Affected versions are Apache MINA 2.0.0 <= 2.0.27, 2.1.0 <= 2.1.10, and 2.2.0 <= 2.2.5. The problem is resolved in Apache MINA 2.0.28, 2.1.11, and 2.2.6 by applying the classname allowlist earlier. Affected are applications using Apache MINA that call IoBuffer.getObject(). Applications using Apache MINA are advised to upgrade.
