AnalysisAIv1 – Aug 17, 2026

Terminal escape sequence injection in powerlevel10k (all versions through 1.20.17) allows any attacker who controls a package.json file on a victim's filesystem to emit arbitrary terminal control sequences on every shell prompt render when the victim navigates into the affected directory. The prompt_package segment in internal/p10k.zsh passed the P9K_PACKAGE_VERSION variable to the terminal without applying Zsh's (V) sanitization flag, meaning raw ANSI or OSC escape bytes in the version field reach the terminal emulator unfiltered. No public exploit or CISA KEV listing is identified at time of analysis; the CVSS 4.0 score of 4.8 reflects limited integrity impact and required user interaction.

DescriptionCVE.org

powerlevel10k fails to neutralize control characters in the package.json version field when rendering the package prompt segment. Attackers can inject raw escape bytes in the version string to emit arbitrary terminal control sequences on each prompt render when the shell enters affected directories.

What every action level means

Emergency Immediate action required. Criteria: CRITICAL + in CISA KEV (actively exploited) without patch, OR CRITICAL + EPSS > 30% without patch, OR CRITICAL + active threat signals without patch.

Act Now Prioritize within 24-48h. Criteria: in KEV with patch available, OR CRITICAL + public POC, OR HIGH + EPSS > 10%, OR CRITICAL + active threat, OR any CRITICAL severity.

This Week Schedule remediation this week. Criteria: HIGH severity (CVSS 7.0-8.9). Patch within normal change window.

This Month Plan within 30 days. Criteria: MEDIUM severity (CVSS 4.0-6.9), lower exploitation probability. Include in regular patch cycle.

Monitor Track and reassess. Criteria: LOW severity (CVSS 0.1-3.9), minimal exploitation risk. No immediate action needed.

Attack Technique

Code Injection CRITICAL

Code injection occurs when an application accepts user input and passes it directly into a language interpreter or evaluator without proper sanitization.
