Entry 38 of 44
Vulnerability
vulnerare — to wound; vulnus — a wound
Latin
From Late Latin vulnerabilis, from vulnerare (to wound), from vulnus (a wound, an injury). Root concept: the capacity to be wounded. The subject of vulnerability is the one who can be hurt.
Established meaning
In ordinary and legal usage: a person, population, or system capable of being harmed. In medicine and disaster law, vulnerability names who will be injured if protection fails. In computer security, a weakness that can be used to cause harm — still, in principle, harm to someone.
AI industry deployment
A CWE category. A scanner output. A severity band (critical, high). The subject of the wound is the codebase, the product, the company's security posture. Persons whose data, labor, or speech sit in the weights are not the grammatical subject of the word as used.
Semantic gap
The one who can be wounded
Vulnus belongs to a body. Industry usage relocates the wound onto software so that the person who can actually be hurt — the user, the source of the training data, the operator of a dependent system — disappears from the sentence. What remains is a ticket.
