CVE-2011-4895 describes a vulnerability in Tor versions prior to 0.2.2.34, specifically when configured as a bridge. The flaw stems from a difference in how bridges build circuits compared to clients, which allows remote attackers to more easily identify and enumerate these bridges. With a CVSS score of 4.3 (medium severity), this vulnerability has a network attack vector and medium attack complexity, potentially leading to information disclosure (CWE-200) by revealing the presence of Tor bridges. There is no evidence of active exploitation, public exploit code, or significant community discussion surrounding this CVE.
