CVE-2025-48924

Vulnerable Library - commons-lang3-3.17.0.jar

Apache Commons Lang, a package of Java utility classes for the classes that are in java.lang's hierarchy, or are considered to be so standard as to justify existence in java.lang.

The code is tested using the latest revision of the JDK for supported
LTS releases: 8, 11, 17 and 21 currently.
See https://github.com/apache/commons-lang/blob/master/.github/workflows/maven.yml

Please ensure your build environment is up-to-date and kindly report any build issues.

Reachability Analysis

This vulnerability is potentially reachable

com.vonage.quickstart.messages.MessageStatusWebhook (Application)
  -> com.vonage.client.messages.MessageStatus (Extension)
   -> com.vonage.client.JsonableBaseObject (Extension)
    -> org.apache.commons.lang3.builder.HashCodeBuilder (Extension)
     -> org.apache.commons.lang3.builder.ReflectionToStringBuilder (Extension)
      -> ❌ org.apache.commons.lang3.ClassUtils (Vulnerable Component)

Vulnerability Details

Uncontrolled Recursion vulnerability in Apache Commons Lang.
This issue affects Apache Commons Lang: Starting with commons-lang:commons-lang 2.0 to 2.6, and, from org.apache.commons:commons-lang3 3.0 before 3.18.0.
The methods ClassUtils.getClass(...) can throw StackOverflowError on very long inputs. Because an Error is usually not handled by applications and libraries, a
StackOverflowError could cause an application to stop.
Users are recommended to upgrade to version 3.18.0, which fixes the issue.
Mend Note: The description of this vulnerability differs from MITRE.

Found in base branch: main

Vulnerability Details

The non-blocking (async) JSON parser in jackson-core bypasses the maxNumberLength constraint (default: 1000 characters) defined in StreamReadConstraints. This allows an attacker to send JSON with arbitrarily long numbers through the async parser API, leading to excessive memory allocation and potential CPU exhaustion, resulting in a Denial of Service (DoS).

The standard synchronous parser correctly enforces this limit, but the async parser fails to do so, creating an inconsistent enforcement policy.
