Description

npm-check-updates through 23.0.2, fixed in commit b554b84, contains a terminal escape sequence injection vulnerability that allows an attacker to embed arbitrary terminal control characters in a dependency's package.json homepage or repository URL fields. When a developer runs ncu with the --format homepage or --format repo option, unfiltered escape sequences are written directly to the terminal, enabling malicious output manipulation or other terminal-dependent effects.

How this vulnerability can be exploited

This issue can be reached over the network, attack complexity is low, an attacker needs no privileges on the target. A user must be tricked into taking some action. The scope is unchanged, so the impact stays within the vulnerable component. Rated impact: confidentiality none, integrity low, availability none.
