## What is CVE-2026-105767?

CVE-2026-105767 is a low-severity command injection vulnerability in Chainguard Academy (edu), published on 5 Oct 2026. An attacker needs administrator access to exploit it, with no action from the victim.

### Official description

Improper Neutralization of Special Elements used in an OS Command in the integrate-platform-docs composite GitHub Action of Chainguard Academy (edu) from commit 7375a80caabcc31c33ec90f29687ed78c13d16ff before commit fb0efb2537d326ab18c07d620875b8ed2a4b39f3 allows an actor who controls the project_id or storage_bucket inputs to execute arbitrary shell commands on the GitHub Actions runner, because the inputs are interpolated directly into Bash gcloud storage cp commands in several steps via ${{ inputs.* }} expressions. The only in-repository caller passed repository secrets and ran only on trusted triggers, so no untrusted input was known to reach the vulnerable steps.

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

What it is: CVE-2026-105767 is a low-severity command injection vulnerability in Chainguard Academy (edu), published on 5 Oct 2026. An attacker needs administrator access to exploit it, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2026-105767 in the wild and no public exploit code.

Affected product: Chainguard Academy (edu). 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.
