CVE-2026-6940: CWE-22 Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') in radareorg radare2
CVE-2026-6940 is a path traversal vulnerability in radare2 versions prior to 6. 1. 4. It allows local attackers to supply absolute paths that escape the intended project directory, enabling recursive deletion of arbitrary directories with the permissions of the radare2 process. This can lead to loss of data integrity and availability. The vulnerability arises during project deletion operations where pathname restrictions are improperly enforced.
AI Analysis
Technical Summary
The vulnerability in radare2 before version 6.1.4 involves improper limitation of pathnames (CWE-22) during project deletion. Local attackers can craft absolute paths to project marker files outside the configured project storage root directory. By doing so, they can cause recursive deletion of directories chosen by the attacker, leveraging the permissions of the radare2 process. This results in potential integrity and availability impacts due to unintended file system modifications.
Potential Impact
Exploitation allows local attackers to delete arbitrary directories recursively, potentially causing significant data loss or service disruption. The attack requires local access and user interaction but does not require elevated privileges beyond those of the radare2 process. The impact includes loss of data integrity and availability within the affected system.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or patch links are currently provided. Until a patch is available, restrict local access to systems running vulnerable versions of radare2 and avoid running radare2 with elevated privileges. Monitor for vendor updates regarding an official fix.
