CVE-2025-46392: Apache Commons Configuration: StackOverflowError loading untrusted configuration

[Arnout Engelen <engelen () apache org>]

Severity: low

Affected versions:

- Apache Commons Configuration 1 before 2.0.0

Description:

Uncontrolled Resource Consumption vulnerability in Apache Commons Configuration 1.x.

There are a number of issues in Apache Commons Configuration 1.x that allow excessive resource consumption when loading 
untrusted configurations or using unexpected usage patterns. The Apache Commons Configuration team does not intend to 
fix these issues in 1.x. Apache Commons Configuration 1.x is still safe to use in scenario's where you only load 
trusted configurations. 


Users that load untrusted configurations or give attackers control over usage patterns are recommended to upgrade to 
the 2.x version line, which fixes these issues. Apache Commons Configuration 2.x is not a drop-in replacement, but as 
it uses a separate Maven groupId and Java package namespace they can be loaded side-by-side, making it possible to do a 
gradual migration.
