• CVE-2026-55153: 0.19% estimated exploitation activity in the next 30 days; percentile 9.21 (FIRST EPSS, 2026-11-03). This is a model estimate, not proof of exploitation or customer exposure.

As published by the source; long descriptions are shortened.

Impact Prior to version 0.6.0, mchange-commons-java includes a JNDI ObjectFactory implementation (com.mchange.v2.naming.JavaBeanObjectFactory) willing to construct objects of arbitrary classes and initialize "JavaBean"-style properties. There are classes for which this kind of initialization is unsafe. For example, setting the "contentType" property of a Swing JEditorPane to text/html and the "text" property to HTML containing a stylesheet <link> will provoke an HTTP GET on an arbitrary URL, potentially from within a trusted security domain. This issue is aggravated by mchange-commons-java's ReferenceIndirector, by which malicious JNDI Reference objects could be smuggled in for dereferencing by applications anywhere a Java-serialized object might be read. Prior to version 0.5.0, the same mchange-commons-java ObjectFactory would interpret BinaryRefAddress elements as Java-serialized objects, and deserialize unexpected objects that potentially execute malicious behavior on…

# Patch Next advisory brief: CVE-2026-55153

Advisory: mchange-commons-java contains elements susceptible to abuse via JNDI injection and "deserialization gadgets"
IDs: CVE-2026-55153, GHSA-h84g-69h7-mw6v
Record: https://patchnext.com/advisories/cve-2026-55153 (revision 2, source checked 26 Oct 2026, 16:54 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: High (CVSS 7.1)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: com.mchange:mchange-commons-java 0.6.0. A vendor fix does not mean a deployment is fixed.

## Affected components
- Maven com.mchange:mchange-commons-java: affected < 0.6.0; fixed in 0.6.0

## Suggested inspection (read-only)
- Maven com.mchange:mchange-commons-java: check the installed version with your package manager.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on com.mchange:mchange-commons-java.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.
