{"cve":"CVE-2026-49836","nvd":{"published":"2026-09-10T22:16:57.300","modified":"2026-09-30T19:57:08.043","status":"Deferred","description":"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.","cvss_v4":{"vector":"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","score":4.6},"cvss_v3":null,"cwes":["CWE-22","CWE-73"],"references":["http://github.com/psd-tools/psd-tools/releases/tag/v1.17.1","https://github.com/psd-tools/psd-tools/pull/657","https://github.com/psd-tools/psd-tools/security/advisories/GHSA-2rmg-vrx8-9j2f","https://github.com/pypa/advisory-database/tree/main/vulns/psd-tools/PYSEC-2026-2969.yaml","https://github.com/psd-tools/psd-tools/security/advisories/GHSA-2rmg-vrx8-9j2f"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:52:53.108888569+00:00"},"epss":{"cve":"CVE-2026-49836","score":0.00192,"percentile":0.08768,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-2rmg-vrx8-9j2f","url":"https://osv.dev/vulnerability/GHSA-2rmg-vrx8-9j2f","summary":"psd-tools vulnerable to arbitrary file write via smart-object filename","modified":"2026-09-10T22:00:05.286860550Z","packages":[{"ecosystem":"PyPI","name":"psd-tools","purl":"pkg:pypi/psd-tools","ranges":["<1.17.1"],"fixed":["1.17.1"]}]},{"id":"PYSEC-2026-2969","url":"https://osv.dev/vulnerability/PYSEC-2026-2969","summary":"psd-tools vulnerable to arbitrary file write via smart-object filename","modified":"2026-07-13T16:33:07.841756813Z","packages":[{"ecosystem":"PyPI","name":"psd-tools","purl":"pkg:pypi/psd-tools","ranges":["<1.17.1"],"fixed":["1.17.1"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
