Airmail 3 for Mac

Vulnerability Details
Airmail’s primary WebView instance implements “webView:decidePolicyForNavigationAction:request:frame:decisionListener:” such that “OpenURL” is the default URL handler. A navigation request is processed by the default URL handler only if the “currentEvent” is “NX_LMOUSEUP” or “NX_OMOUSEUP”. An attacker may abuse HTML Elements with an EventHandler for a chance to validate navigation requests for URLs that are processed during the “NX_LMOUSEUP” event triggered by clicking an email.
