Apache Commons Configuration
Monthly
Uncontrolled recursion in Apache Commons Configuration 2.2 through 2.14.x allows remote attackers to trigger a denial of service via StackOverflowError when processing YAML configuration files containing cyclic object references. The vulnerability affects any application using the library to parse untrusted YAML input without validation, with CVSS 5.3 (network-accessible, no authentication required) but exceptionally low exploitation probability (EPSS 0.02%, percentile 5%), indicating this is primarily a defensive hardening fix rather than an actively exploited threat.
