CVE-2026-107152: Red Hat product Improper Authentication Vulnerability

A flaw was found in Foreman’s Api::V2::PersonalAccessTokensController, where Foreman::Controller::UserAware#find_user resolves the target account using User.find(params[:user_id]) without applying the required parent-user authorization check. An attacker with the create_personal_access_tokens permission can therefore invoke POST /api/v2/users/:user_id/personal_access_tokens with another user’s ID and create a Personal Access Token on their behalf. The resulting plaintext token is returned in the API response, while PersonalAccessToken#check_permissions_after_save only validates create_personal_access_tokens on the token and does not enforce edit_users authorization on the target user. The attacker can then use the forged token to authenticate as the victim, potentially resulting in complete account takeover, including administrator accounts.

A missing authorization check has been found in ConsumerResource.setupOwner() function of consumer registration module in the Candlepin package. The registration method checks permission to create a consumer only when the caller is a user. A consumer that authenticates with its identity certificate does not go through that check. A low-privileged network attacker or user who has a valid consumer certificate for one organization can register a new consumer in a different organization by supplying that organization's key. The response includes an identity certificate for the new consumer. With that certificate, the attacker can view the target organization's subscription pools. When the organization is not using simple content access, the attacker can attach that organization's entitlements to the new consumer.

A flaw was found in Foreman. An authenticated user with view_hosts privileges can retrieve rendered provisioning template content for a host via the hosts template API endpoint, disclosing sensitive data such as the host root password. This is an incomplete fix of CVE-2026-96659, which hardened the web UI preview path but left the API host-template render path authorized for Viewer-level users.

A flaw was found in rubygem-safemode. Compound assignment expressions in sandboxed code are evaluated without mediating method calls through the Jail allow-list. An authenticated attacker who can supply template content can invoke arbitrary no-argument methods on objects exposed to the template renderer without Jail mediation, including destructive operations such as host deletion and disclosure of non-allow-listed object state.

A flaw was found in yggdrasil-worker-package-manager. An authenticated attacker can exploit this issue to achieve arbitrary file modification or potential privilege escalation. The vulnerability exists because repository management operations fail to sanitize directory traversal sequences (such as '../') within repository names. By supplying a crafted repository name, an attacker can manipulate the root-level worker process into creating or deleting files outside the intended directory, compromising host system integrity.

A flaw was found in freeradius. An improper length validation in the EAP-FAST module allows a stack-based buffer overflow during session ticket processing. A remote, unauthenticated attacker can exploit this flaw by sending a specially crafted handshake request, causing the server process to crash and resulting in a Denial of Service (DoS).
