CVE-2026-48700
A flaw in PCManFM-Qt allows a local user to trigger arbitrary program execution by passing a regular file path as a URI to the ShowFolders D‑Bus method. The product follows the specification, but the behavior can be abused to run code or bypass network namespace limits.
No official fix yet. If none appears within 45 days of first tracking, this entry is removed automatically.
Who is affected
All PCManFM‑Qt releases from version 1.1.0 onward, used by Linux desktop users who rely on the file manager’s D‑Bus integration.
Real-world impact
An attacker who can run commands locally could cause the file manager to launch an arbitrary program, potentially leading to full system compromise or the ability to escape restricted network namespaces.
Why this severity
The CVSS score of 9.3 reflects local access with low authentication, no user interaction, and high impact on confidentiality, integrity, and availability. The vulnerability can be exploited by a local user to execute code and bypass network restrictions, justifying the critical rating.
What to do about it
No official fix or mitigation is documented in the sources yet. Monitor the vendor advisory and apply the patch as soon as it is released.
