CVE-2023-41329

21
FAUCET Score

CVE-2023-41329 is a DNS rebinding vulnerability in WireMock, a tool for mocking HTTP services, affecting various WireMock versions and related products. This medium-severity vulnerability (CVSS 6.6) allows an attacker with control over a DNS service to bypass network restrictions in WireMock's proxy mode due to a race condition between initial validation and the outbound request. While it has high execution complexity and limited impact, it could lead to unauthorized access to prohibited domains. There is currently no evidence of active exploitation, public exploit code, or significant community discussion.
