A flaw was found in Subversion. When using path-based authorization (authz), the helper function detect_changed() does not omit potentially sensitive information from log messages. In particular, if a node is copied from a protected location, its ‘copyfrom’ path (the path to the protected location) is reported even when omission should occur.
