CVE-2026-45205: CWE-674 Uncontrolled Recursion in Apache Software Foundation Apache Commons Configuration
CVE-2026-45205 is an uncontrolled recursion vulnerability in Apache Commons Configuration affecting versions from 2. 2 up to but not including 2. 15. 0. When processing untrusted YAML configuration files containing cycles, the library throws a StackOverflowError. This issue can cause application crashes or denial of service. The Apache Software Foundation recommends upgrading to version 2. 15. 0, which addresses this vulnerability.
AI Analysis
Technical Summary
Apache Commons Configuration versions 2.2 through before 2.15.0 contain an uncontrolled recursion vulnerability (CWE-674) triggered by YAML input with cyclic references. When such input is processed, the library fails to detect the cycle and recurses indefinitely, resulting in a StackOverflowError. This can disrupt application stability by causing crashes. The issue is fixed in version 2.15.0.
Potential Impact
The vulnerability causes a StackOverflowError when processing maliciously crafted YAML configuration files with cycles, leading to potential application crashes or denial of service. There is no indication of code execution or data compromise from the provided data.
Mitigation Recommendations
Users should upgrade Apache Commons Configuration to version 2.15.0, which fixes the uncontrolled recursion issue. Patch status is not explicitly stated but the vendor recommendation to upgrade indicates an official fix is available. No other mitigations are specified.
