{"id":"DEBIAN-CVE-2026-48700","details":"An issue was discovered in all versions of PCManFM-Qt starting from 1.1.0. When a regular file's path is passed as a URI in an org.freedesktop.FileManager1.ShowFolders D-Bus method call, PCManFM-Qt delegates to a different program (based on the file type) without user confirmation. This could be used to achieve code execution or circumvent network namespace restrictions. NOTE: those outcomes are potentially unwanted by most users; however, the behavior of the product does comply with the applicable specification, and a simplistic solution (ensuring that the URI does not name a regular file) may have adverse consequences for I/O.","modified":"2026-09-14T17:03:16.120506167Z","published":"2026-05-22T19:17:04.623Z","upstream":["CVE-2026-48700"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-48700"}],"affected":[{"package":{"name":"pcmanfm-qt","ecosystem":"Debian:12","purl":"pkg:deb/debian/pcmanfm-qt?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.2.1-1","1.3.0-1","1.3.0-2","1.3.0-3","1.4.0-1","1.4.0-2","1.4.0-3","2.0.0-1","2.0.0-1~exp1","2.1.0-1","2.1.0-2","2.2.0-1","2.2.0-1~exp1","2.3.0-1","2.3.0-1~exp1","2.4.0-1"],"ecosystem_specific":{"urgency":"unimportant"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-48700.json"}},{"package":{"name":"pcmanfm-qt","ecosystem":"Debian:13","purl":"pkg:deb/debian/pcmanfm-qt?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.1.0-2","2.2.0-1","2.2.0-1~exp1","2.3.0-1","2.3.0-1~exp1","2.4.0-1"],"ecosystem_specific":{"urgency":"unimportant"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-48700.json"}},{"package":{"name":"pcmanfm-qt","ecosystem":"Debian:14","purl":"pkg:deb/debian/pcmanfm-qt?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.1.0-2","2.2.0-1","2.2.0-1~exp1","2.3.0-1","2.3.0-1~exp1","2.4.0-1"],"ecosystem_specific":{"urgency":"unimportant"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-48700.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H/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:N/R:I/V:D/RE:M/U:Clear"}]}
