Outdated Dependency
Noun · Security & Infosec
Definitions
A library, package, or component version that is older than the currently maintained release and may contain known vulnerabilities, bugs, or unsupported behavior. Outdated dependencies are a common source of supply-chain risk because they often persist unnoticed deep in application stacks.
In plain English: A software component that is old and no longer up to date, possibly leaving known flaws unpatched.
Example: "The scanner found an outdated dependency buried in a transitive package chain that still exposed a critical RCE."
