CVE-2026-58015
Glib: path traversal in glib/gio/gdbusauthmechanismsha1.c via keyring_lookup_entry and mechanism_client_data_receive
Description
A flaw was found in GLib. The D-Bus client-side implementation of the DBUS_COOKIE_SHA1 SASL authentication mechanism does not validate the cookie_context parameter received from the server. A malicious D-Bus server can supply a cookie_context containing path traversal sequences, causing the client to read an arbitrary file and exfiltrate sensitive data by verifying guessed file contents against a generated hash.
