Description

This security bulletin contains information about 1 vulnerability.


1) Improper Neutralization of Escape, Meta, or Control Sequences (CVE-ID: CVE-2026-45803)

CWE-ID: CWE-150 - Improper Neutralization of Escape, Meta, or Control Sequences

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:A/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a remote user to manipulate terminal output.

The vulnerability exists due to improper neutralization of terminal escape sequences in the `gh run view` log output handling when displaying GitHub Actions workflow logs. A remote user can embed terminal escape sequences in workflow log content to manipulate terminal output.

User interaction is required when a victim views logs with gh run view --log or gh run view --log-failed, and the practical impact depends on the terminal emulator in use.
