Root Cause Analysis
The vulnerability stems from insecure XML parser configuration in the SubversionChangeLogParser class. The commit diff shows security features were added to the Digester initialization (disallow-doctype-decl, external entity handling). The parse() method (inherited from ChangeLogParser) uses this Digester instance to process XML input. In vulnerable versions (<2.13.2), the absence of these security features in the parser configuration made XXE exploitation possible when processing attacker-controlled changelog files.
