Vulnerability from github – Published: 2026-04-16 03:31 – Updated: 2026-04-16 03:31

Details

radare2 prior to version 6.1.4 contains a command injection vulnerability in the PDB parser's print_gvars() function that allows attackers to execute arbitrary commands by embedding a newline byte in the PE section header name field. Attackers can craft a malicious PDB file with specially crafted section names to inject r2 commands that are executed when the idp command processes the file.

Severity ?

8.4 (High)
