{"schema":"threatline.record/2","record":{"id":"CVE-2026-94422","aliases":["GHSA-2cgv-pwcq-wvpq"],"summary":"xdg-dbus-proxy: message filtering bypass via reply serial allows sandbox escape","details":"An incorrect implementation of message filtering in xdg-dbus-proxy versions before 0.1.9 allows an attacker to bypass the intended message filtering on the D-Bus session bus by setting a reply serial number on non-reply messages. A malicious or compromised Flatpak app could use this to achieve arbitrary code execution outside its sandbox. xdg-dbus-proxy was designed to be part of the sandbox boundary for Flatpak, but it is released as a separate project and is sometimes used by other app frameworks such as Firejail.","categories":["Unclassified"],"product":"","vendor":"","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-94422","source_modified_at":"2026-10-24T03:08:12.584Z","fetched_at":"2026-10-24T05:41:33.294140Z","product":null,"vendor":null,"versions":[{"version":"0","lessThan":"0.1.9","versionType":"semver","status":"affected"}],"defaultStatus":"unaffected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-94422","source_modified_at":"2026-10-24T03:08:12.584Z","fetched_at":"2026-10-24T05:41:33.294140Z","product":"Fedora","vendor":"Fedora","versions":[{"version":"0","lessThan":"0.1.9","versionType":"semver","status":"affected"}],"defaultStatus":"unaffected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-94422","source_modified_at":"2026-10-24T03:08:12.584Z","fetched_at":"2026-10-24T05:41:33.294140Z","product":"Red Hat Enterprise Linux 9","vendor":"Red Hat","versions":[],"defaultStatus":"affected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-94422","source_modified_at":"2026-10-24T03:08:12.584Z","fetched_at":"2026-10-24T05:41:33.294140Z","product":"Red Hat Enterprise Linux 10","vendor":"Red Hat","versions":[],"defaultStatus":"affected"}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-94422","source_modified_at":"2026-10-24T03:08:12.584Z","fetched_at":"2026-10-24T05:41:33.294140Z","package":{"name":null,"ecosystem":null},"version":"0.1.9","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-94422","source_modified_at":"2026-10-24T03:08:12.584Z","fetched_at":"2026-10-24T05:41:33.294140Z","package":{"name":"Fedora","ecosystem":null},"version":"0.1.9","basis":"first unaffected version stated in the CVE record"}],"cvss":8.8,"severity":"High","kev":{"listed":false},"epss":{"probability":0.00693,"percentile":0.52385,"score_date":"2026-10-23"},"published_at":"2026-10-02T13:54:10.589Z","modified_at":"2026-10-24T03:08:12.584Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-94422","fetched_at":"2026-10-24T05:41:33.294140Z","source_modified_at":"2026-10-24T03:08:12.584Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-94422","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://access.redhat.com/security/cve/CVE-2026-94422","tags":["vendor-advisory"]},{"source":"CVE List","url":"https://github.com/flatpak/xdg-dbus-proxy/security/advisories/GHSA-2cgv-pwcq-wvpq","tags":["third-party-advisory"]},{"source":"CVE List","url":"https://github.com/flatpak/xdg-dbus-proxy/commit/e5702fca4dba9600721921fbca2dbc39dc5ca400","tags":["patch"]},{"source":"CVE List","url":"https://github.com/flatpak/xdg-dbus-proxy/commit/fc027f759316fb2a6c45648200b6f100202eb84e","tags":["patch"]},{"source":"CVE List","url":"https://github.com/flatpak/xdg-dbus-proxy/commit/e4465a0dfe96da3b39929a30a1ac3a22b16223e3","tags":["patch"]},{"source":"CVE List","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2542235","tags":["issue-tracking"]},{"source":"CVE List","url":"https://lists.debian.org/debian-lts-announce/2026/10/msg00050.html"}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"no","technical_impact":"total","assessed_at":"2026-10-02T16:51:24.840136Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-24T03:08:12.584Z","content_hash":"ae391494f6794018dc9137a6d4e11824fbc47f1f9806790351f711db7b3b137d"}}
