| CVE-2026-71577 | 1 Redhat | 1 Multicluster Globalhub | 2026-09-29 | 6.3 Medium |
| A flaw was found in multicluster-global-hub. During a ManagedClusterMigration, the system incorrectly grants all managed hubs read access to a shared communication topic. This allows a compromised managed hub to intercept and collect sensitive bootstrap kubeconfigs, which contain API server tokens intended for other hubs. These tokens have an extended validity of approximately 9.86 years, significantly increasing the risk of unauthorized access and information disclosure to other managed clusters. | ||||
| CVE-2026-96284 | 2 Flatpak, Redhat | 2 Flatpak, Enterprise Linux | 2026-09-29 | 2.5 Low |
| A malicious user can get read-access to files in the flatpak-system-helper context if a system OCI repository is configured, because the OCI code paths in the system helper follow symlinks when importing OCI images that are under the user's control. | ||||
| CVE-2026-66792 | 1 Redhat | 6 Acm, Advanced Cluster Management For Kubernetes, Multicluster Globalhub and 3 more | 2026-09-29 | 9.9 Critical |
| A flaw was found in the multicloud-operators-subscription component. This vulnerability allows a user on a managed cluster to escalate their privileges by creating a Subscription with specific, crafted annotations. Successful exploitation grants the attacker the ability to deploy resources into any namespace with the elevated permissions of the controller's Service Account, potentially leading to unauthorized access and control over cluster resources. | ||||
| CVE-2026-71576 | 1 Redhat | 1 Multicluster Globalhub | 2026-09-29 | 8.5 High |
| A flaw was found in multicluster-global-hub. The manager component improperly validates the source identity of incoming CloudEvents on Kafka status topics. A remote attacker, after compromising a managed hub and obtaining its Kafka client certificate, can manipulate the self-asserted source identity. This allows the attacker to falsify or delete critical data, such as compliance, inventory, and cluster health information, belonging to other hubs in the database. | ||||
| CVE-2026-95520 | 1 Redhat | 2 Enterprise Linux, Hummingbird | 2026-09-29 | 7.1 High |
| A heap-based buffer overflow flaw was found in rpm. Parsing a symlink entry in an untrusted RPM package whose declared RPMTAG_LONGFILESIZES value is 0xFFFFFFFFFFFFFFFF causes an integer overflow in iterReadArchiveNext() that shrinks a buffer allocation to one byte, after which the payload's independently-controlled cpio filesize field is used to write attacker-controlled data past the end of that allocation. This is reachable via rpm2cpio, rpm2archive, and rpm -qlvp on an untrusted package. | ||||
| CVE-2026-97023 | 2 Flatpak, Redhat | 2 Flatpak, Enterprise Linux | 2026-09-29 | 7.1 High |
| A path traversal vulnerability in Flatpak's handling of the export/bin directory during app deployment allows a malicious Flatpak app to cause deletion of attacker-chosen files outside the deployment directory when the app is installed or upgraded. In system-wide installations, the deletion is performed as root. | ||||
| CVE-2026-97024 | 2 Flatpak, Redhat | 2 Flatpak, Enterprise Linux | 2026-09-29 | 7.1 High |
| A path traversal vulnerability in Flatpak's handling of the files/etc directory during app deployment allows a malicious Flatpak app to cause certain host system files (such as passwd, group, machine-id, or resolv.conf) to be emptied or replaced with a symlink when the app is installed or upgraded. In system-wide installations, the write is performed as root. | ||||
| CVE-2026-97029 | 2 Flatpak, Redhat | 2 Flatpak, Enterprise Linux | 2026-09-29 | 5.7 Medium |
| Flatpak's process ID namespace separation does not prevent a sandboxed app's kill(0, signal) or killpg(0, signal) calls from reaching processes outside the sandbox that share the same process group. A malicious or compromised Flatpak app can use this to cause denial of service by terminating processes outside its sandbox, such as the desktop shell. | ||||
| CVE-2023-6393 | 1 Redhat | 2 Build Of Quarkus, Quarkus | 2026-09-29 | 5.3 Medium |
| A flaw was found in the Quarkus Cache Runtime. When request processing utilizes a Uni cached using @CacheResult and the cached Uni reuses the initial "completion" context, the processing switches to the cached Uni instead of the request context. This is a problem if the cached Uni context contains sensitive information, and could allow a malicious user to benefit from a POST request returning the response that is meant for another user, gaining access to sensitive data. | ||||
| CVE-2026-96541 | 2 Gnome, Redhat | 2 Gnome-remote-desktop, Enterprise Linux | 2026-09-28 | 7.5 High |
| A denial-of-service flaw was found in gnome-remote-desktop. An unauthenticated remote attacker can open RDP connections without completing the handshake and retain the connection-throttling slots indefinitely because no pre-authentication handshake deadline is enforced. By exhausting the global connection limit, an attacker can prevent new RDP clients from connecting until a holding socket is closed. | ||||
| CVE-2026-97176 | 1 Redhat | 3 Build Keycloak, Red Hat Single Sign On, Single Sign-on | 2026-09-28 | 4.2 Medium |
| A flaw was found in the Level of Authentication enforcement mechanism of Keycloak, an identity and access management solution. The issue occurs when a client specifically requires a higher security level for a user who already has an active session at a lower level. Due to a logic error in how session re-evaluations are handled, Keycloak may incorrectly issue a token at the lower security level instead of enforcing the required higher level, potentially allowing unauthorized access to sensitive resources that rely on these security claims. | ||||
| CVE-2026-97177 | 1 Redhat | 4 Build Keycloak, Build Of Keycloak, Red Hat Single Sign On and 1 more | 2026-09-28 | 6.6 Medium |
| A flaw was found in the user update mechanism of the Keycloak Admin REST API. When Fine-Grained Admin Permissions are enabled, the system fails to check for specific password reset authorizations during a general user profile update. This allows a delegated administrator, who should be restricted from resetting passwords, to change a user's credentials and take over their account. | ||||
| CVE-2026-95519 | 2 Redhat, Rpm | 4 Enterprise Linux, Hardened Images, Hummingbird and 1 more | 2026-09-28 | 7.8 High |
| A flaw was found in rpm. An attacker can supply a crafted manifest file that, when processed by a user or automation using `rpm -q -p` or similar manifest-processing flows, leads to arbitrary code execution. This occurs because manifest entries are unexpectedly macro-expanded before being opened, allowing embedded shell commands to run with the privileges of the `rpm` process. Successful exploitation can lead to a full compromise of confidentiality, integrity, and availability for the affected account. | ||||
| CVE-2026-95521 | 2 Redhat, Rpm | 4 Enterprise Linux, Hardened Images, Hummingbird and 1 more | 2026-09-28 | 7.8 High |
| A command injection flaw was found in rpm. Installing or rebuilding a source RPM whose source or spec file basenames contain a %() macro construct causes rpm to execute an attacker-controlled shell command via popen() while relocating the source file list. This allows arbitrary command execution as the invoking (typically non-root) user, simply by installing, rebuilding, or otherwise processing an untrusted .src.rpm. | ||||
| CVE-2026-101333 | 1 Redhat | 4 Build Keycloak, Build Of Keycloak, Red Hat Single Sign On and 1 more | 2026-09-28 | 3.7 Low |
| A flaw was found in the Micrometer user-event metrics listener of Keycloak, a solution for integrated identity and access management. The issue occurs when the listener is configured to include the idp tag. An unauthenticated attacker can send requests to the identity broker login endpoint using arbitrary provider aliases, causing the system to create an unlimited number of metric time series. This can lead to excessive memory consumption and degrade the performance of both the server and its monitoring tools. | ||||
| CVE-2026-97311 | 1 Redhat | 4 Build Keycloak, Build Of Keycloak, Red Hat Single Sign On and 1 more | 2026-09-28 | 4.3 Medium |
| A flaw was found in the Admin REST API of Keycloak, an identity and access management solution. The endpoints used to retrieve groups associated with a specific role do not properly check for individual group visibility permissions. This allows a delegated administrator with basic search privileges to view detailed information about all groups assigned to a role, bypassing intended security restrictions that should limit their view to specific groups. | ||||
| CVE-2026-96448 | 1 Redhat | 4 Build Keycloak, Build Of Keycloak, Red Hat Single Sign On and 1 more | 2026-09-28 | 6.6 Medium |
| A flaw was found in the Fine-Grained Admin Permissions (FGAP v2) feature of Keycloak, an identity and access management solution. The issue occurs when the system checks if a delegated administrator has permission to assign a specific role to a user. Because the check does not look inside composite roles to see what other permissions they contain, an administrator with limited rights can assign a role that secretly includes full administrative control. This allows the attacker to gain complete management access over the entire realm. | ||||
| CVE-2026-97846 | 1 Redhat | 4 Build Keycloak, Build Of Keycloak, Red Hat Single Sign On and 1 more | 2026-09-28 | 6.8 Medium |
| Keycloak provides a feature called mTLS holder-of-key binding which ensures that a token can only be used by the client that originally requested it by binding it to their digital certificate. A flaw was discovered where the new Standard Token Exchange V2 feature does not check for this certificate. This allows an attacker with stolen client credentials to obtain a standard, unrestricted token that bypasses these security protections. | ||||
| CVE-2026-100691 | 2 Gohugo, Redhat | 2 Hugo, Hummingbird | 2026-09-28 | 5.4 Medium |
| Hugo versions 0.75.0 through 0.165.x contain a stored cross-site scripting vulnerability: the syntax highlighter does not escape the `lineAnchors` option before passing it to Chroma, which writes the value verbatim into the `id` and `href` attributes of the generated line-number markup. A crafted `lineAnchors` value supplied as a Markdown code fence attribute (or passed to the `highlight` template function) results in unescaped HTML in the rendered page, allowing arbitrary JavaScript to execute in the browsers of visitors to the generated site. This affects sites that build and publish Markdown from untrusted contributors; Hugo's security model otherwise considers content trusted input. Fixed in 0.166.0, where the `lineAnchors` value is HTML-escaped before being passed to Chroma. | ||||
| CVE-2026-100692 | 2 Gohugo, Redhat | 2 Hugo, Hummingbird | 2026-09-28 | 7.5 High |
| Hugo is a static site generator. In versions after v0.123.0 and before v0.166.0, Hugo's symlink confinement checks stopped at the mount root itself, so a theme or module checked into themes/ (or a vendored module) could contain a symlink at a mount root (for example themes/mytheme/assets -> /some/dir/outside). Files behind such a symlink were readable during a site build through resources.Get, resources.Match and similar functions, and could be published to public/ via static mounts, bypassing the rule that theme and module mount sources must be local paths. Modules fetched via Go modules are not affected because Go module zips cannot contain symlinks, and this is not an escalation for the main project, which may already mount absolute paths by configuration. Fixed in v0.166.0, where symlinked mount roots and symlinked directories between the mount root and the module directory are treated as non-existent for all modules. As a workaround, inspect themes/ and vendored modules for symlinks at mount roots before building, or replace symlinks with explicit mounts. | ||||
