Doc Text:
A flaw was found in radare2 that could lead to arbitrary operating system (OS) command execution. A local user could be exploited through a command injection vulnerability in the PDB (Program Database) parser. By processing a specially crafted malicious PDB file, the `idp` command would execute arbitrary radare2 commands, enabling the attacker to run commands on the underlying operating system.

Description OSIDB Bzimport 2026-04-22 23:01:19 UTC 
radare2 prior to 6.1.4 contains a command injection vulnerability in the PDB parser's print_gvars() function that allows attackers to execute arbitrary commands by crafting a malicious PDB file with newline characters in symbol names. Attackers can inject arbitrary radare2 commands through unsanitized symbol name interpolation in the flag rename command, which are then executed when a user runs the idp command against the malicious PDB file, enabling arbitrary OS command execution through radare2's shell execution operator.
