An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-94422 in the wild and no public exploit code.\n\nAffected product: Fedora. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-94422/ (Markdown: https://insights.sbomify.com/CVE-2026-94422/index.md)","id":"CVE-2026-94422","markdown":"https://insights.sbomify.com/CVE-2026-94422/index.md","name":"CVE-2026-94422","record":{"aliases":["ALSA-2026:90522","ALSA-2026:90523","AZL-105923","DEBIAN-CVE-2026-94422","ECHO-ab97-ca4d-bc8e","GHSA-2cgv-pwcq-wvpq","MGASA-2026-0480","OESA-2026-4640","OESA-2026-4641","OESA-2026-4642","OESA-2026-4643","RLSA-2026:90522","RLSA-2026:90523","UBUNTU-CVE-2026-94422"],"analysis":{"component_type":"operating_system","fix_type":"upgrade","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"Flatpak sandbox proxy","requires_auth":"none","summary":"Attackers can bypass D-Bus message filtering in xdg-dbus-proxy to escape Flatpak sandboxes and execute arbitrary code.","user_interaction":"required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[],"cvss":{"score":8.7,"severity":"high","source":"cna","vector":"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","version":"4.0"},"cwes":[{"id":"CWE-290","name":"Authentication Bypass by Spoofing"}],"description":"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.
