Impact

DefaultHttpClient follows redirects and forwards Authorization, Cookie, and Proxy-Authorization headers to redirect targets across domain boundaries. The blocklist only filters Host/Connection/TE/CT/CL. Additionally, no maximum redirect count exists, enabling infinite loop DoS. Affected: DefaultHttpClient.java lines 231-245, 1591, 2071
Suggested fix: Strip sensitive headers on cross-domain redirects
