Description OSIDB Bzimport 2026-08-19 19:03:39 UTC 
The acm-operator-bundle build fetches whatever is at stolostron/release@master HEAD at run time and execs tools/konflux/common/process-triggering-pr.sh from it. There is no commit-SHA pin, no checksum, and no signature verification. The exec'd script inherits the full environment of the triggering step, including a GitHub App token scoped to all repos under github.repository_owner, registry passwords for registry.redhat.io/registry.stage.redhat.io/quay.io, and write access to the bundle PR that becomes the shipped ACM operator bundle. (Related weakness: CWE-494, Download of Code Without Integrity Check.)
