Summary
A flaw was found in olm-operator-konflux-sample. The bundle builder stage installs and upgrades Python packages using pip, a package installer, without verifying their versions or using hash verification.
This allows a malicious or compromised package to be introduced into the build process undetected, potentially leading to a supply chain compromise where untrusted code is incorporated into software builds. This vulnerability has a Low impact on Konflux environments.
Exploitation requires an attacker to compromise a package release or the build process itself, making it difficult to achieve. Red Hat severity: Low — CVSS 2.6 (CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:U/C:L/I:N/A:N).
Weakness: CWE-494.

Mitigation checklist
- To mitigate this issue, ensure that the bundle builder stage for `olm-operator-konflux-sample` uses pinned versions and hash verification for pip dependencies. This can be achieved by dropping the `--upgrade pip` command, vendoring a hash-pinned `requirements.txt` file, and installing dependencies using `pip3 install --no-deps --require-hashes -r requirements.txt`. Alternatively, prefetch pip inputs via Cachi2 to ensure a hermetic build process. Implementing these changes will require adjustments to the build pipeline configuration.
