It was originally part of the flatpak project, but it has been broken out as a standalone module to facilitate using it in other contexts.\r\n\r\nSecurity Fix(es):\n\nAn 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.(CVE-2026-94422)","affected":[{"package":{"ecosystem":"openEuler:24.03-LTS-SP1","name":"xdg-dbus-proxy","purl":"pkg:rpm/openEuler/xdg-dbus-proxy&distro=openEuler-24.03-LTS-SP1"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.1.2-3.oe2403sp1"}]}],"ecosystem_specific":{"aarch64":["xdg-dbus-proxy-0.1.2-3.oe2403sp1.aarch64.rpm","xdg-dbus-proxy-debuginfo-0.1.2-3.oe2403sp1.aarch64.rpm","xdg-dbus-proxy-debugsource-0.1.2-3.oe2403sp1.aarch64.rpm"],"noarch":["xdg-dbus-proxy-help-0.1.2-3.oe2403sp1.noarch.rpm"],"src":["xdg-dbus-proxy-0.1.2-3.oe2403sp1.src.rpm"],"x86_64":["xdg-dbus-proxy-0.1.2-3.oe2403sp1.x86_64.rpm","xdg-dbus-proxy-debuginfo-0.1.2-3.oe2403sp1.x86_64.rpm","xdg-dbus-proxy-debugsource-0.1.2-3.oe2403sp1.x86_64.rpm"]}}],"references":[{"type":"ADVISORY","url":"https://www.openeuler.org/zh/security/security-bulletins/detail/?id=openEuler-SA-2026-4641"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-94422"}],"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H"}],"database_specific":{"severity":"High"}}
