CVE-2022-41939

MEDIUM

knative.dev/func < 1.8.1 - Exposure of Sensitive Information via Malicious Buildpack Lifecycle Container

Title source: llm
STIX 2.1

Description

knative.dev/func is is a client library and CLI enabling the development and deployment of Kubernetes functions. Developers using a malicious or compromised third-party buildpack could expose their registry credentials or local docker socket to a malicious `lifecycle` container. This issues has been patched in PR #1442, and is part of release 1.8.1. This issue only affects users who are using function buildpacks from third-parties; pinning the builder image to a specific content-hash with a valid `lifecycle` image will also mitigate the attack.
