CVE-2024-24784: Comments in display names are incorrectly handled in net/mail

• Severity: high (CVSS 7.5 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 1.1% probability of exploitation in the next 30 days
• Public exploit or detection template: none known
• Published: 2024-03-05 · updated 2026-06-17

Description

The ParseAddressList function incorrectly handles comments (text within parentheses) within display names. Since this is a misalignment with conforming address parsers, it can result in different trust decisions being made by programs using different parsers.

Affected products

• Go standard library Net/Mail: before 1.21.8; from 1.22.0-0 before 1.22.1 — fixed in 1.21.8, 1.22.1

How to fix

Upgrade to a fixed version: Go standard library Net/Mail 1.21.8, 1.22.1. Check the vendor advisory for mitigations.
