mchange-commons-java JNDI Injection & Deserialization Vulnerability (CVE-2026-55153)

Vulnerability Overview versions prior to 0.6.0 are vulnerable to JNDI injection and deserialization gadgets. Attackers can construct malicious JNDI reference objects to execute arbitrary code by exploiting the class in . Additionally, this library contains known deserialization gadgets such as and , which can be triggered under specific conditions. Affected Scope Affected Versions: = 0.6.0 Remediation 1. Upgrade to the Latest Version: - Upgrade to version 0.6.0 or higher. - If an immediate upgrade is not possible, it is recommended to upgrade to >= 0.9.4.0 or higher and gradually replace during the upgrade process. 2. Disable Deserialization Mechanisms: - In 0.6.0, the mechanism is disabled by default to prevent the triggering of deserialization gadgets via JNDI injection. - For applications that require enabling the mechanism, configure it cautiously to ensure no security risks are introduced. 3. Use Serialization Filters: - Maintaining strict serialization filters can prevent many attacks, particularly those that only require constructing named classes and initializing simple JavaBeans properties. 4. Avoid JNDI References: - Avoid searching for malicious JNDI references or deserializing malicious Java-serialized objects in your application. - If JNDI references must be used, ensure their source is trusted and avoid executing them in untrusted environments. Reference Links GitHub Repository GitHub Security Advisory Additional Information CVSS Score: 7.1 / 10 CVSS Vector: CVE ID: CVE-2026-55153 Summary versions prior to v0.6.0 are vulnerable to JNDI injection and deserialization gadgets, allowing attackers to execute arbitrary code. It is recommended to upgrade to v0.6.0 or higher as soon as possible and implement corresponding security measures to prevent potential attacks.
