What is CVE-2026-6941?

radare2, prior to version 6.1.4, is susceptible to a path traversal vulnerability affecting its project notes handling feature. By exploiting a crafted .zrp archive containing a symlinked notes.txt file, an attacker can circumvent directory confinement measures. This can lead to unauthorized file read or write operations outside the designated project directory, potentially exposing sensitive data and system files. Properly configured systems should ensure updates are applied to mitigate this security risk.

Affected Version(s)

radare2 0 < 6.1.4

radare2 0 < 4bcdee725ff0754ed721a98789c0af371c5f32a4

Exploit Proof of Concept (PoC)

PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
