Improper Input Validation vulnerability in Apache Camel Mail component.

This issue affects Apache Camel: from 4.0.0 before 4.18.5, from 4.19.0 before 4.22.1.

CVE-2026-46584 addressed mail headers reaching the Exchange without passing through a header filter, but the MimeMultipart data format retained an unfiltered path: unmarshalling a multipart message mapped mail.smtp headers onto the Exchange with no filter applied.

Read full descriptionShow less

Those names sit outside the Camel namespace that consumer filters block, so a message crafted by an external sender could still set them, and the mail.smtp namespace influences how a downstream mail producer connects and sends. This is an incomplete fix of CVE-2026-46584 rather than a new class of defect: a deployment that applied that advisory and considered camel-mail settled remained exposed on this path.

Upgrade to Apache Camel 4.23.0, which fixes the issue. Users on the 4.18.x LTS releases stream should upgrade to 4.18.5. Users on the 4.22.x LTS releases stream should upgrade to 4.22.1. The MimeMultipart data format now applies the header filter on unmarshal, closing the path CVE-2026-46584 left open. For deployments that cannot upgrade immediately, strip the namespace after the data format with removeHeaders("mail.smtp*") before any mail producer.

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).

Public exploits

Exploit code or detection templates are publicly available. This is not the same as confirmed active exploitation (KEV), but it raises the risk: patch with priority.

⚠️ GitHub proofs of concept are not verified: some are fake or contain malware. Never run them outside an isolated lab.
