CVE-2026-40499 is a high-severity flaw (CVSS 7.8) affecting radare2. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
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.
Why this priority
- High severity
- Public exploit reference
A fixed release or distro patch exists.
