CVE-2018-1294: Apache Commons Email

High severity, CVSS 7.5. EPSS: 2.8% chance of exploitation in the next 30 days.

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).

Affected products

• Apache Commons Email: from 1.0, up to and including 1.4
