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.","evidence":"cve:CVE-2026-94422","products":[{"name":{"value":"Fedora","evidence":"/containers/cna/affected/1/product"},"prerequisites":[],"fixed_versions":[],"affected_versions":[]},{"name":{"value":"Red Hat Enterprise Linux 9","evidence":"/containers/cna/affected/2/product"},"prerequisites":[],"fixed_versions":[],"affected_versions":[]},{"name":{"value":"Red Hat Enterprise Linux 10","evidence":"/containers/cna/affected/3/product"},"prerequisites":[],"fixed_versions":[],"affected_versions":[]}],"severity":"high","structured":{"id":"CVE-2026-94422","aliases":["CVE-2026-94422"],"metrics":[{"other":{"type":"Red Hat severity rating","content":{"value":"Important","namespace":"https://access.redhat.com/security/updates/classification/"}}},{"format":"CVSS","cvssV3_1":{"scope":"UNCHANGED","version":"3.1","baseScore":8.8,"attackVector":"NETWORK","baseSeverity":"HIGH","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","integrityImpact":"HIGH","userInteraction":"REQUIRED","attackComplexity":"LOW","availabilityImpact":"HIGH","privilegesRequired":"NONE","confidentialityImpact":"HIGH"}},{"format":"CVSS","cvssV4_0":{"version":"4.0","baseScore":8.7,"attackVector":"NETWORK","baseSeverity":"HIGH","vectorString":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","userInteraction":"PASSIVE","attackComplexity":"LOW","attackRequirements":"NONE","privilegesRequired":"NONE","subIntegrityImpact":"NONE","vulnIntegrityImpact":"HIGH","subAvailabilityImpact":"NONE","vulnAvailabilityImpact":"HIGH","subConfidentialityImpact":"NONE","vulnConfidentialityImpact":"HIGH"}}],"affected":[{"versions":[{"status":"affected","version":"0","lessThan":"0.1.9","versionType":"semver"}],"packageName":"xdg-dbus-proxy","collectionURL":"https://github.com/flatpak/xdg-dbus-proxy","defaultStatus":"unaffected"},{"vendor":"Fedora","product":"Fedora","versions":[{"status":"affected","version":"0","lessThan":"0.1.9","versionType":"semver"}],"packageName":"xdg-dbus-proxy","collectionURL":"https://bodhi.fedoraproject.org/updates/?packages=xdg-dbus-proxy","defaultStatus":"unaffected"},{"cpes":["cpe:/o:redhat:enterprise_linux:9"],"vendor":"Red Hat","product":"Red Hat Enterprise Linux 9","packageName":"xdg-dbus-proxy","collectionURL":"https://access.redhat.com/downloads/content/package-browser/","defaultStatus":"affected"},{"cpes":["cpe:/o:redhat:enterprise_linux:10"],"vendor":"Red Hat","product":"Red Hat Enterprise Linux 10","packageName":"xdg-dbus-proxy","collectionURL":"https://access.redhat.com/downloads/content/package-browser/","defaultStatus":"affected"}],"modified":"2026-10-24T03:08:12.584Z","provider":"cve","references":["https://access.redhat.com/security/cve/CVE-2026-94422","https://github.com/flatpak/xdg-dbus-proxy/security/advisories/GHSA-2cgv-pwcq-wvpq","https://github.com/flatpak/xdg-dbus-proxy/commit/e5702fca4dba9600721921fbca2dbc39dc5ca400","https://github.com/flatpak/xdg-dbus-proxy/commit/fc027f759316fb2a6c45648200b6f100202eb84e","https://github.com/flatpak/xdg-dbus-proxy/commit/e4465a0dfe96da3b39929a30a1ac3a22b16223e3","https://bugzilla.redhat.com/show_bug.cgi?id=2542235"],"provider_metadata":{"adp":[{"title":"CVE Program Container","references":[{"url":"http://www.openwall.com/lists/oss-security/2026/09/23/5"},{"url":"https://lists.debian.org/debian-lts-announce/2026/10/msg00050.html"}],"providerMetadata":{"orgId":"af854a3a-2127-422b-91ae-364da2661108","shortName":"CVE","dateUpdated":"2026-10-24T03:08:12.584Z"}},{"title":"CISA ADP Vulnrichment","metrics":[{"other":{"type":"ssvc","content":{"id":"CVE-2026-94422","role":"CISA Coordinator","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"total"}],"version":"2.0.3","timestamp":"2026-10-02T16:51:24.840136Z"}}}],"providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-10-02T16:51:40.902Z"}}],"cna":{"orgId":"53f830b8-0a3f-465b-8143-3b8a9948e749","shortName":"redhat","dateUpdated":"2026-10-02T13:54:10.589Z"}}},"related_cves":[{"value":"CVE-2026-94422","evidence":"/cveMetadata/cveId"}],"security_relevant":true,"severity_evidence":"/containers/cna/metrics"}}],"next_after":8042,"next_before":8042}
