Vulnerability Title
Chainguard Academy (edu) integrate-platform-docs composite action interpolates inputs into shell commands
Source: CVE Program / CVE List V5
Vulnerability 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.
