CVE-2026-44936 Details
Description
Missing filtering when the helmRepoURLRegex field isn't set on a GitRepo resource in SUSE Rancher Fleet's bundle reader in 0.15 before 0.15.2, 0.14 before 0.14.6, 0.13 before 0.13.11 and 0.12 before 0.12.15 forwards Helm authentication credentials (BasicAuth) to any URL specified in the helm.repo field of a fleet.yaml file, allowing attackers able to push to fleet monitored git repos to leak helm access credentials.
A vulnerability exists in SUSE Rancher Fleet's bundle reader, specifically in versions 0.15 prior to 0.15.2, 0.14 prior to 0.14.6, 0.13 prior to 0.13.11, and 0.12 prior to 0.12.15. The issue arises from missing validation when the 'helmRepoURLRegex' field is not specified on a 'GitRepo' resource. This flaw allows Helm authentication credentials (BasicAuth) to be forwarded to any URL indicated in the 'helm.repo' field of a 'fleet.yaml' file. Consequently, attackers with the ability to push to Git repositories monitored by Fleet can intercept Helm access credentials.
To address this vulnerability, upgrade to Fleet versions 0.15.2, 0.14.6, 0.13.11, or 0.12.15. After upgrading, set the 'helmRepoURLRegex' field on all 'GitRepo' resources that use 'helmSecretName'. If 'helmRepoURLRegex' is empty or missing, Fleet will not forward credentials. For resources created after the upgrade, 'helmRepoURLRegex' must be set manually. Consult the Fleet documentation for guidance on managing 'GitRepo' resources.
