CVE-2026-41046

Local service interruption via unchecked configuration paths

Published Jun 22, 2026 · Updated Jun 22, 2026

Relative path traversal in qSnapper before 1.3.3 allows local users to hang or crash its privileged D-Bus service via configName. All D-Bus methods pass configName directly to libsnapper as a basename without rejecting slashes or dot-dot components, so crafted paths select arbitrary configuration files. Locally logged-in users can reach list-snapshots methods without authentication, causing memory exhaustion or blocking; arbitrary writes and root escalation require admin access or a separate Polkit bypass.
