{"id":"CVE-2026-58015","aliases":[],"url":"https://o3.security/vulnerability/CVE-2026-58015","summary":"Glib: path traversal in glib/gio/gdbusauthmechanismsha1.c via keyring_lookup_entry and mechanism_client_data_receive","details":"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.","published":"2026-06-30T13:02:45.854Z","modified":"2026-10-09T10:30:50.482649445Z","cvss":{"score":5.9,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N"},"epss":{"score":0.00661,"percentile":0.49742,"asOf":"2026-09-15"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://access.redhat.com/downloads/content/package-browser/"},{"type":"WEB","url":"https://catalog.redhat.com/software/containers/"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:49512"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:55440"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:57015"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:58981"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:61766"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:61783"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:63135"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:63138"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:63140"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:65762"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:65763"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:65767"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:65768"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:65769"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:65770"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:65771"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:65773"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:66018"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:66357"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:70646"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:72394"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:72395"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:72399"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:72470"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:72475"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:72476"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:72502"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:73859"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:73909"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:73929"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:73930"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:73959"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:73960"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:73961"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:73962"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:74458"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:74459"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:74460"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:74461"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:74462"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:74463"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:74674"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:74677"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:74678"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:74679"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:74681"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:74683"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:74685"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:74687"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:74688"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:74771"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:75652"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:75654"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:75655"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:75657"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:75658"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:75659"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:75660"},{"type":"ADVISORY","url":"https://access.redha
