The Hummingbird WordPress plugin before 3.4.2 does not validate the generated file path for page cache files before writing them, leading to a path traversal vulnerability in the page cache module.

The Hummingbird WordPress plugin before 3.3.2 does not sanitise and escape the Config Name, which could allow high privilege users, such as admin to perform cross-Site Scripting attacks even when the unfilteredhtml capability is disallowed

Multiple insecure method vulnerabilities in the DeployRun.DeploymentSetup.1 (DeployRun.dll) ActiveX control 10.0.0.44 in Hummingbird Deployment Wizard 2008 allow remote attackers to execute arbitrary programs via the (1) Run and (2) PerformUpdateAsync methods, and (3) modify arbitrary registry values via the SetRegistryValueAsString method. NOTE: the SetRegistryValueAsString method could be leveraged for code execution by specifying executable file values to Startup folders.

Stack-based buffer overflow in Hummingbird.XWebHostCtrl.1 ActiveX control (hclxweb.dll) in Hummingbird Xweb ActiveX Control 13.0 and earlier allows remote attackers to execute arbitrary code via a long PlainTextPassword property. NOTE: code execution might not be possible in 13.0.
