# CVE-2026-48700

## Summary

- **CVE ID:** CVE-2026-48700
- **Severity:** CRITICAL
- **CVSS Score:** 9.3 (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/AU:N/R:I/V:D/RE:M/U:Clear)
- **CWE:** CWE-913
- **Published:** May 22, 2026
- **Last Modified:** May 24, 2026

## Description

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.

## Affected Products

- LXQt — PCManFM-Qt (1.1.0)
