{"id":"DEBIAN-CVE-2026-49836","details":"psd-tools is a Python package for working with Adobe Photoshop PSD files. Prior to version 1.17.1, `SmartObject.save()` writes an embedded smart object to a path taken verbatim from the PSD file. Because that name is attacker-controlled and unsanitised, a tool that extracts embedded objects from an untrusted `.psd` can be made to write attacker-chosen bytes to an attacker-chosen path (absolute or `../`-traversing), outside its intended output directory. A secondary issue in `SmartObject.open()` for external-kind smart objects allows the attacker-controlled `fullPath` descriptor to be used as an arbitrary file read path, enabling exfiltration of the read content to the controlled write destination. Both issues are fixed in v1.17.1.","modified":"2026-09-12T08:47:26.962457920Z","published":"2026-09-10T22:16:57.300Z","upstream":["CVE-2026-49836"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-49836"}],"affected":[{"package":{"name":"psd-tools","ecosystem":"Debian:12","purl":"pkg:deb/debian/psd-tools?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.10.7+dfsg.1-1","1.10.9+dfsg.1-1","1.12.0+dfsg.1-1","1.12.1+dfsg.1-1","1.14.2+dfsg.1-1","1.14.3+dfsg.1-1","1.15.0+dfsg.1-1","1.16.0+dfsg.1-1","1.17.0+dfsg.1-1","1.17.4+dfsg.1-1","1.9.24+dfsg.1-1","1.9.28+dfsg.1-1","1.9.30+dfsg.1-1","1.9.31+dfsg.1-1","1.9.32+dfsg.1-1","1.9.34+dfsg.1-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-49836.json"}},{"package":{"name":"psd-tools","ecosystem":"Debian:13","purl":"pkg:deb/debian/psd-tools?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.10.7+dfsg.1-1","1.10.7+dfsg.1-1+deb13u1","1.10.9+dfsg.1-1","1.12.0+dfsg.1-1","1.12.1+dfsg.1-1","1.14.2+dfsg.1-1","1.14.3+dfsg.1-1","1.15.0+dfsg.1-1","1.16.0+dfsg.1-1","1.17.0+dfsg.1-1","1.17.4+dfsg.1-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-49836.json"}},{"package":{"name":"psd-tools","ecosystem":"Debian:14","purl":"pkg:deb/debian/psd-tools?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.17.4+dfsg.1-1"}]}],"versions":["1.10.7+dfsg.1-1","1.10.9+dfsg.1-1","1.12.0+dfsg.1-1","1.12.1+dfsg.1-1","1.14.2+dfsg.1-1","1.14.3+dfsg.1-1","1.15.0+dfsg.1-1","1.16.0+dfsg.1-1","1.17.0+dfsg.1-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-49836.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:L/VI:L/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"}]}
