AnalysisAIv1 – Aug 13, 2026

Terminal escape sequence injection in Oh My Posh prior to version 29.35.1 allows an attacker who controls a Git repository or filesystem directory name to silently execute arbitrary ANSI/OSC escape sequences in a victim's terminal on every prompt render, without any user action beyond navigating to the attacker-influenced directory. The write(s rune) function in src/terminal/writer.go emitted attacker-controlled content — including Git commit subjects, author names and emails, upstream URLs, and working directory path components — verbatim to the terminal output buffer without stripping C0/C1 control characters such as ESC (0x1b), BEL (0x07), CSI, and OSC sequences. A publicly available proof-of-concept demonstrates OSC 52 clipboard overwrite and OSC 0 window title hijacking; no public exploit identified as confirmed actively exploited per CISA KEV at time of analysis.

DescriptionCVE.org

Oh My Posh is the most customisable and low-latency cross platform/shell prompt renderer. Prior to 29.35.1, write(s rune) in src/terminal/writer.go emitted attacker-controlled current directory names and Git metadata, including Commit.Subject, Commit.Author.Name, Commit.Author.Email, and RawUpstreamURL, without removing C0/C1 terminal control characters such as ESC, BEL, CSI, and OSC, allowing terminal escape sequence injection during prompt rendering that could overwrite the clipboard, spoof the prompt or screen, manipulate the window title, or disrupt the terminal. This issue is fixed in version 29.35.1.

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.

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.
