Title
Nodemailer 3.0.0 before 10.1.4 Address Parsing Bypass via Nested Comments
Summary
Nodemailer from 3.0.0 before 10.1.4 contains an address parsing vulnerability in addressparser that allows remote attackers to redirect recipients by ending nested RFC 5322 comments at the first closing parenthesis. Attackers can submit addresses whose nested comment hides an attacker address, bypassing conformant validators and recipient allow lists to receive mail or spoof senders in mailparser.

Drag nodes to arrange them. Double-click a related vulnerability to open it, or a source to visit its link. The Physics button on the left tunes the layout and the simulation; the legend at the bottom left hides or shows nodes by kind and by sighting type.
Experimental. This forecast is provided for visualization only and may change without notice. Do not use it for operational decisions.
Forecast uses a logistic model when the trend is rising, or an exponential decay model when the trend is falling. Fitted via linearized least squares.
