## What is CVE-2026-26982?

CVE-2026-26982 is a medium-severity command injection vulnerability in ghostty-org ghostty, published on 9 Mar 2026. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.

### Official description

Ghostty is a cross-platform terminal emulator. Ghostty allows control characters such as 0x03 (Ctrl+C) in pasted and dropped text. These can be used to execute arbitrary commands in some shell environments. This attack requires an attacker to convince the user to copy and paste or drag and drop malicious text. The attack requires user interaction to be triggered, but the dangerous characters are invisible in most GUI environments so it isn't trivially detected, especially if the string contents are complex. Fixed in Ghostty v1.3.0.

Weakness: CWE-78 (Improper Neutralization of Special Elements used in an OS Command)

Affected product: ghostty-org ghostty. No package-level version data is available, so check the vendor advisory linked from the reference page.

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
