Vulnerability description

DayBreach CVE AI Research

CVE-2026-58015 has vendor, distribution, patch and security-source records on file. We can compare them and prepare an explanation linked to the evidence.

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.
