CVE-2026-45803
Github Cli 1.6.0 – 2.92.0
Raw vector
CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:N/I:L/A:NSummary
CVE-2026-45803 is a low-severity Improper Neutralization of Escape, Meta, or Control Sequences (CWE-150) vulnerability in Github Cli. Its CVSS base score is 3.5 (Low).
Operationally, exploitation aligns with the MITRE ATT&CK technique Content Injection (T1659); ranked at the 11th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
The strongest mitigations our analysis identified map to SI-10 (Information Input Validation) — see the control section below for these in your framework.

Vulnerability Data
`gh` is GitHub’s official command line tool. From 1.6.0 to before 2.92.0, a security vulnerability has been identified in GitHub CLI that could allow terminal escape sequence injection when users view GitHub Actions workflow logs using gh run view --log…
more
or gh run view --log-failed. The vulnerability stems from the way GitHub CLI handles raw Actions log output. The gh run view --log and gh run view --log-failed commands stream workflow log lines to stdout or the configured pager without sanitizing terminal control sequences. An attacker who can influence GitHub Actions log content, for example via a PR triggered workflow, can embed escape sequences that are replayed in the user's terminal when they inspect the run. Depending on the victim's terminal emulator, injected sequences could change the window title, manipulate on screen content, or in some terminal emulators (such as screen) potentially execute arbitrary commands. This vulnerability is fixed in 2.92.0.

SI-10 requires validation/sanitization of inputs that directly stops escape/meta/control sequences from reaching downstream components.

Secure SDLC practices directly require input neutralization and escaping to prevent this class of flaw.

Security testing can detect the weakness but does not itself implement neutralization.
Secure development lifecycle mandates input validation and output encoding that directly neutralizes escape/meta sequences.
Application security requirements explicitly call for controls against injection and malformed input sequences.
Secure architecture principles reduce attack surface but do not prescribe specific neutralization techniques.
Secure coding standards require proper escaping and neutralization of control characters before downstream processing.
