CVE-2026-73035 PUBLISHED

npm-check-updates 23.0.2 Terminal Injection via Unsanitized Escape Sequences

Assigner: VulnCheck
Reserved: 10.08.2026 Published: 10.08.2026 Updated: 10.08.2026

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.
