{"id":"DEBIAN-CVE-2026-103433","details":"Docker Buildx Bake does not request the expected fs.read approval for certain filesystem inputs. An untrusted Bake definition can expose a readable file through a pathless secret whose ID is interpreted as a client-side pathname, or consume a local OCI image layout outside the project after entitlement validation checks a different path representation. Users who run untrusted Bake definitions are affected.","modified":"2026-10-07T09:47:34.473274297Z","published":"2026-10-05T22:16:56.370Z","upstream":["CVE-2026-103433"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-103433"}],"affected":[{"package":{"name":"docker-buildx","ecosystem":"Debian:13","purl":"pkg:deb/debian/docker-buildx?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.13.1+ds1-3","0.19.3+ds1-1","0.19.3+ds1-2","0.19.3+ds1-3","0.19.3+ds1-4","0.29.1+ds1-1","0.29.1+ds1-2","0.29.1+ds1-3","0.29.1+ds1-4"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-103433.json"}},{"package":{"name":"docker-buildx","ecosystem":"Debian:14","purl":"pkg:deb/debian/docker-buildx?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.13.1+ds1-3","0.19.3+ds1-1","0.19.3+ds1-2","0.19.3+ds1-3","0.19.3+ds1-4","0.29.1+ds1-1","0.29.1+ds1-2","0.29.1+ds1-3","0.29.1+ds1-4"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-103433.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X"}]}
