CVE-2025-54314

Thor before 1.4.0 can construct an unsafe shell command from library input.

LOW 2.8EPSS 0.16%

Does this matter?

Lower severity and a low EPSS score (0.16%). Track it; it rarely justifies an emergency change on its own.

Description

Thor before 1.4.0 can construct an unsafe shell command from library input. NOTE: this is disputed by the Supplier because "the method that was fixed can only be used with arguments that are controlled by Thor, and there is no way an attacker can take control of those arguments."
