Detailsinfo

A vulnerability was found in radareorg radare2 up to 6.1.3. It has been rated as critical. This issue affects some unknown processing. The manipulation with an unknown input leads to a path traversal vulnerability. Using CWE to declare the problem leads to CWE-22. The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

radare2 prior to 6.1.4 contains a path traversal vulnerability in project deletion that allows local attackers to recursively delete arbitrary directories by supplying absolute paths that escape the configured dir.projects root directory. Attackers can craft absolute paths to project marker files outside the project storage boundary to cause recursive deletion of attacker-chosen directories with permissions of the radare2 process, resulting in integrity and availability loss.

The weakness was published by Chia Min Jun Lennon. The advisory is shared at github.com. The identification of this vulnerability is CVE-2026-6940 since 04/23/2026. The exploitation is known to be easy. An attack has to be approached locally. Neither technical details nor an exploit are publicly available. MITRE ATT&CK project uses the attack technique T1006 for this issue.

The vulnerability scanner Nessus provides a plugin with the ID 310839 (Linux Distros Unpatched Vulnerability : CVE-2026-6940), which helps to determine the existence of the flaw in a target environment.
