Doc Text:
A flaw was found in Trivy, a security scanner. The plugin manager does not properly confine plugin names to their designated root directory. This allows an attacker, by persuading a user to install or run a malicious plugin, to write the plugin manifest and binary to arbitrary user-writable paths. This could lead to unauthorized file modification on the system.

Description OSIDB Bzimport 2026-08-18 15:40:52 UTC
Trivy is a security scanner. Prior to 0.72.0, plugin manifest metadata is used by pkg/plugin/manager.go to construct paths under ~/.trivy/plugins without confining plugin names to that root, allowing an attacker who persuades a user to install or run a malicious plugin to write the manifest and plugin binary to arbitrary user-writable paths, while plugins from the official Trivy plugin index are not affected. This issue is fixed in version 0.72.0.
