CVE-2023-42508Network attack vector

Email body manipulation via improper header validation

Published Oct 3, 2023 · Updated Sep 19, 2024

Improper input validation in JFrog Artifactory before 7.66.0 allows remote attackers to send emails with manipulated bodies. An unspecified endpoint fails to validate crafted header input before incorporating attacker-controlled content into an outbound email body. No account is required, all deployments are exposed, and a recipient must interact with the resulting email for the rated impact.
