NewCVE-2026-85314 (opens in a new tab)How to fix?
Upgrade org.apache.camel:camel-mail to version 4.18.5, 4.22.1 or higher.
Overview
org.apache.camel:camel-mail is a Camel Mail support.
Affected versions of this package are vulnerable to Incomplete Filtering of Special Elements via MimeMultipartDataFormat in the camel-mail component. An external sender can supply a multipart message with mail.smtp.* or mail.smtps.* headers that are copied onto the Exchange during inline-header unmarshalling. If the route passes that Exchange to a downstream mail producer, the attacker can influence how it connects and sends mail.
Notes
- The injection path requires a route to use
MimeMultipartDataFormatwithheadersInlineenabled; otherwise multipart headers are not copied onto the Exchange.
Workarounds
- After
MimeMultipartDataFormatunmarshalling, removemail.smtp*headers withremoveHeaders("mail.smtp*")before any mail producer to prevent attacker-supplied SMTP properties from influencing how it connects and sends mail.
