Description OSIDB Bzimport 2026-09-22 18:34:28 UTC 
A specially crafted WS-Policy document with deeply nested policy elements can bypass Neethi's nesting-depth limit and exhaust the thread stack, crashing the parser (denial of service).
Users are recommended to upgrade to version 3.2.4, which fixes this issue.
