NVD Description

Note: Versions mentioned in the description apply only to the upstream unleash package and not the unleash package as distributed by Chainguard. See How to fix? for Chainguard relevant fixed versions and status.

nodemailer before 9.0.1 fails to apply disableFileAccess and disableUrlAccess flags to message-level raw option, allowing authenticated attackers to read arbitrary files or perform server-side request forgery by supplying path or href properties. Attackers can exploit this by crafting raw messages with file paths or URLs that bypass the intended sandbox, with fetched content delivered in the outgoing message to attacker-controlled recipients.
