High (7.5) in apache commons email. EPSS 2.8% chance of exploitation in the next 30 days. Fixed in org.apache.commons:commons-email 1.5.
If a user of Apache Commons Email (typically an application programmer) passes unvalidated input as the so-called "Bounce Address", and that input contains line-breaks, then the email details (recipients, contents, etc.) might be manipulated. Mitigation: Users should upgrade to Commons-Email 1.5. You can mitigate this vulnerability for older versions of Commons Email by stripping line-breaks from data, that will be passed to Email.setBounceAddress(String).
