Command execution via non-directory PATH elements
Published Sep 18, 2025 · Updated Sep 18, 2025
Input misinterpretation in Go standard library os/exec before 1.23.12 and 1.24.0 through 1.24.5 allows attackers to execute binaries. LookPath joins each PATH element with an empty, dot, or dot-dot argument and accepts a non-directory executable as a successful resolution. Exploitation requires control of the argument, filesystem, and PATH; on Windows, a writable parent of a PATH entry can suffice without PATH control.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=0 <1.23.12
- Affected versionversion=1.24.0 <1.24.6
