CVE-2026-107443

Foreman: foreman: api host template render discloses secrets to view_hosts users (incomplete cve-2026-96659 fix)

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.

Rubygem-safemode: safemode: jail allow-list bypass via op-assign expressions

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.

Rubygem-smart_proxy_dynflow: dynflow console authorizes any client certificate the capsule ca signed

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.

Ansible-core: ansible-core: ansible.builtin.git invokes git without a `--` separator, allowing argument injection via a `-`-leading repository url (e.g. --upload-pack) -> rce

A flaw was found in ansible-core's ansible.builtin.git module. The module invokes git (ls-remote, clone, fetch) with the repository URL as a positional argument and without a "--" separator, so a repository URL that begins with a dash is interpreted by git as a command-line option. A caller that passes an attacker-controlled repository URL to the module can trigger argument injection (for example --upload-pack/--exec), resulting in arbitrary command execution on the host running the module.

Foreman: api filter lookup ignores a search-limited filter permission

A flaw has been found in **permission filters** in the **foreman** package. The API loads a filter by its identifier and does not apply the search limit on the caller's permission. A low-privileged network attacker or user must already be allowed to delete filters for one role only. They can delete filters that belong to other unlocked roles. Those other roles then lose the access the deleted filters had granted.

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 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.

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.

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.

Foreman: cross-tenant disclosure of template revisions via unauthorized audit lookup

A flaw was found in Foreman. The template revision endpoint does not enforce object-level authorization when retrieving an audited template revision. An authenticated, low privileged user with a template-related permission, such as view_ptables, can obtain historical template contents belonging to another organization or location by supplying the corresponding audit ID. This can result in unauthorized disclosure of historical template contents, which may contain sensitive configuration information, credentials, or other secrets. The REST API revision endpoints correctly restrict this lookup.

Mirror-registry: quay: server-side request forgery in proxy cache upstream registry configuration

A flaw was found in Red Hat Quay's Proxy Cache configuration feature. When an organization administrator configures an upstream registry for proxy caching, Quay makes a network connection to the specified registry hostname without verifying that it points to a legitimate external service. An attacker with organization administrator privileges could supply a crafted hostname to force the Quay server to make requests to internal network services, cloud infrastructure endpoints, or other resources that should not be accessible from the Quay application.

Registry tokens signed with that key are accepted for any repository, allowing read and write access to private images and replacement of repository tags.
