CVE-2024-1724: snapd allows $HOME/bin symlink

• Severity: high (CVSS 8.2 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.3% probability of exploitation in the next 30 days
• Public exploit or detection template: yes
• Published: 2024-07-25 · updated 2026-06-17
• Weakness: CWE-732

Description

In snapd versions prior to 2.62, when using AppArmor for enforcement of sandbox permissions, snapd failed to restrict writes to the $HOME/bin path. In Ubuntu, when this path exists, it is automatically added to the users PATH. An attacker who could convince a user to install a malicious snap which used the 'home' plug could use this vulnerability to install arbitrary scripts into the users PATH which may then be run by the user outside of the expected snap sandbox and hence allow them to escape confinement.

Affected products

• Canonical Ltd. snapd: before 2.62 — fixed in 2.62

How to fix

Upgrade to a fixed version: Canonical Ltd. snapd 2.62. Check the vendor advisory for mitigations.
