CVE-2026-123177

Dnf5: dnf5daemon-server: dnf5daemon-server: unauthenticated privileged cmdline package fetch/open via add_cmdline_packages

A flaw was found in dnf5daemon-server. Unauthenticated D-Bus methods pass caller-controlled URL or .rpm path patterns into a root-privileged cmdline package loader that may store fetched content in a world-readable cache without size limits, or open local paths as root, allowing a local attacker to disclose privileged content and to deny service via disk exhaustion.

Rubygem-foreman_remote_execution: job output readable without object-level view_job_invocations check

A flaw was found in the foreman_remote_execution plugin's template invocations controller. The show_template_invocation_by_host action resolves the job invocation by ID without evaluating the caller's view_job_invocations permission filter against the record. An authenticated user whose job invocation visibility is restricted by a permission filter can enumerate job invocation IDs and read the live output, rendered script, and input values for other users' job invocations within their own organizations.

Rubygem-foreman_ansible: ansible inventory api ignores view_hosts permission filters, exposes hidden parameters

A flaw was found in the foreman_ansible plugin's Ansible inventory API. The controller builds its host query using an unscoped Host.where call that does not enforce the search filter associated with the caller's view_hosts permission. An authenticated user whose host visibility is restricted by a permission filter can supply arbitrary host IDs within their organization and receive the full Ansible inventory for those hosts, including parameter values marked as hidden.

Pulp-rpm: distribution tree publish creates directories from .treeinfo ids

A flaw was found in pulp-rpm when it publishes a distribution tree. Addon and variant ids from .treeinfo are used as directory names. A user who can sync or upload that tree can make the publish task create a new directory outside the task work area and write that tree's repository metadata and packages there, as the Pulp worker user. An existing file or directory is not replaced. The flaw does not disclose data and does not stop the service.

Foreman: authorization flaw in the foreman::controller::useraware handling used by api::v2::sshkeyscontroller

A flaw was found in Foreman’s Api::V2::SshKeysController, where the target user is resolved through Foreman::Controller::UserAware#find_user using User.find(params[:user_id]) without enforcing the required parent-user authorization check. An attacker with the create_ssh_keys permission can exploit this authorization bypass by submitting POST /api/v2/users/:user_id/ssh_keys with another user’s ID and injecting their own public SSH key into the targeted account. The injected key is subsequently propagated to hosts provisioned by that user, potentially allowing the attacker to authenticate to and gain SSH access to the victim’s managed hosts.

Foreman: authorization flaw in the mail-notification endpoints implemented by api::v2::mailnotificationscontroller

A flaw was found in Foreman’s Api::V2::MailNotificationsController, where authorization checks on user-specific mail-notification resources are insufficient. The GET /api/v2/users/:id/mail_notifications endpoint resolves the target account using User.find(params[:id]) without verifying that the authenticated user is authorized to access that user’s notification configuration. Additionally, the POST and PUT /api/v2/users/:user_id/mail_notifications paths call deny_access when the requester is unauthorized but fail to halt execution, allowing the request to continue and persist the unauthorized change despite a 403 response or subsequent DoubleRenderError. This can allow a user to disclose another user’s mail-notification configuration, including mail_query values, and, where write permissions apply, modify or create notification settings for another user.

Rubygem-katello: cross-tenant content view filter rule access and modification via unauthorized parent filter lookup

A flaw was found in Katello where the Content View Filter Rules API does not properly enforce authorization on the parent Content View Filter. An authenticated, low-privileged user with Content View permissions in one organization may be able to access and modify filter rules belonging to a Content View Filter in another organization by supplying that filter's identifier. This can result in unauthorized disclosure of filter-rule information and unauthorized changes to unpublished Content View filter configuration.

Candlepin: consumer certificate can register systems in another organization

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.

An improper authentication vulnerability has been found in the task console in the smart_proxy_dynflow package. The console accepts any client certificate signed by the capsule's certificate authority. It does not check the list of servers the capsule trusts. A low-privileged network attacker or user must already hold such a certificate. They can open the console and read job details. Those details include passwords when a job was given them. They can also cancel a running task.

Candlepin: candlepin: broken object-level authorization via verifyauthorizationfilter multi-@verify hasaccess latching

A flaw was found in Candlepin. The central authorization filter incorrectly grants access when any one of multiple @Verify-annotated parameters is accessible, instead of requiring access to every verified entity. A low-privilege authenticated attacker who can access the first referenced object can bypass authorization checks on subsequent objects. When target resource identifiers are known, this can enable unauthorized disclosure of consumer information and unauthorized modification of entitlements and related subscription resources, including across organizations.

CVE-2026-90959

Pulpcore: pulpcore: file:// scheme allowlist bypass in content upload file_url field enables arbitrary file read and pulp container registry signing key theft

A path traversal vulnerability was found in pulpcore. The content upload API accepts a 'file_url' parameter that allows users with file repository privileges to specify a local file URL for Pulp to download and store. A URL scheme validation check uses a string prefix comparison that only rejects URLs beginning with 'file://', but Python's URL parser recognizes the 'file:' scheme without double slashes, creating a mismatch between what is validated and what is dispatched to the file downloader. An authenticated user with low-privilege repository permissions can supply a specially crafted URL using relative path traversal sequences to read any file accessible to the Pulp server process. In deployments that include Pulp Container, successful exploitation allows an attacker to read the container registry token signing private key and forge bearer tokens, granting unauthorized access to all private container repositories in the affected registry.

Foreman: authorization flaw in the foreman::controller::useraware#find_user handling used by api::v2::personalaccesstokenscontroller

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.

Sequoia-openpgp: sequoia-openpgp: cryptographic integrity compromise via key flag confusion

A flaw was found in sequoia-openpgp. The library incorrectly infers key flags for older certificates when a key flags subpacket is missing, leading to a discrepancy in how key capabilities are viewed. This key flag confusion allows an attacker to bypass the back-signature check. Consequently, an attacker can illegitimately bind an arbitrary subkey to their own certificate and forge signatures, completely compromising cryptographic integrity.

The system certificate authority (CA) store in Red Hat products, distributed via ca-certificates RPM packages, included multiple root CA certificates of authorities, which signed intermediate CA certificates with weak private keys issued by the eMudhra certificate authority. A man-in-the-middle attacker could use this flaw to issue certificates for arbitrary host names signed by the weak intermediate CA certificates, which would be considered trusted by a TLS/SSL client using system CA store and cause such clients to connect to malicious sites. Due to inability to only distrust specific intermediate certificates in all clients using the system CA store, root CA certificates of authorities that signed weak intermediate CA certificates are being removed.
