CVE-2026-13316 2 Redhat, Theforeman 2 Satellite, Foreman 2026-07-06 N/A 4.4 MEDIUM
A flaw has been found in foreman when HTTP parameters are modified in http_proxies_controller and http_proxy files. Attackers can perform an SSRF attack and steal cloud metadata service on AWS/GCP/Azure environment through foreman component.
CVE-2026-13322 2 Kubevirt, Redhat 2 Kubevirt, Openshift Virtualization 2026-07-06 N/A 3.8 LOW
A flaw was found in KubeVirt's downward metrics virtio-serial server. The server reads guest requests using textproto.Reader.ReadLine(), which buffers input indefinitely until a newline character is received, with no length limit or read deadline. A user with access to a VM guest that has the downward metrics virtio-serial device configured can write a continuous byte stream to the device, causing unbounded memory allocation in the virt-handler process until it is OOM-killed.
CVE-2024-51127 1 Redhat 1 Hornetq 2026-07-05 N/A 7.1 HIGH
An issue in the createTempFile method of hornetq v2.4.9 allows attackers to arbitrarily overwrite files or access sensitive information.
CVE-2026-2340 2 Redhat, Samba 3 Enterprise Linux, Openshift Container Platform, Samba 2026-07-02 N/A 6.5 MEDIUM
A flaw was found in Samba’s vfs_worm module. The module is intended to provide write-once, read-many (WORM) protections by preventing modification of files after a configurable grace period. Due to insufficient validation during rename operations, an authenticated user with write access to a share could overwrite a protected file by renaming a newly created file over the existing WORM-protected file.
CVE-2026-12388 1 Redhat 1 Build Of Keycloak 2026-07-01 N/A 6.5 MEDIUM
A flaw was found in the Identity Provider (IdP) mapper component of Keycloak, which is used to manage how user information from external services is mapped to Keycloak users. An administrator with limited permissions to manage identity providers can exploit this flaw by creating a "Hardcoded Role" mapper that assigns high-level administrative roles (like realm-admin) to themselves or others. This allows a restricted administrator to bypass security checks and gain full control over the entire realm.
CVE-2026-14209 1 Redhat 2 Build Of Keycloak, Jboss Enterprise Application Platform Expansion Pack 2026-07-01 N/A 4.3 MEDIUM
A vulnerability was discovered in Keycloak's Admin UI extension that allows certain administrative users to bypass security restrictions. When Fine-Grained Admin Permissions (FGAPv2) are enabled, an administrator who should only be able to search for users (but not view their full details) can use a specific "brute-force-user" endpoint to access a user's full profile. This includes sensitive information and security metadata. The issue occurs because the system fails to check if the administrator has the required "view" permission for that specific user when using this particular search path.
CVE-2026-4629 1 Redhat 1 Build Of Keycloak 2026-07-01 N/A 6.5 MEDIUM
A flaw was found in Keycloak. A highly privileged user with `manage-clients` permission can exploit this vulnerability by injecting a hardcoded role mapper into any client. This action allows the user to bypass existing scope restrictions and inject the `realm-admin` role into generated tokens, resulting in privilege escalation and full administrative access to the realm.
CVE-2026-9705 1 Redhat 1 Build Of Keycloak 2026-07-01 N/A 6.5 MEDIUM
A flaw was found in Keycloak's client registration service. A remote attacker, possessing a previously issued Registration Access Token (RAT), could exploit this vulnerability to re-enable a client that an administrator had explicitly disabled. This bypasses security controls, allowing the attacker to reset the client's secret and potentially regain privileged API access. The primary impact includes unauthorized information disclosure and potential integrity compromise.
CVE-2026-9799 1 Redhat 1 Build Of Keycloak 2026-07-01 N/A 4.6 MEDIUM
A flaw was found in org.keycloak.authorization. An authenticated user with a granted User-Managed Access (UMA) permission ticket for one resource can exploit this by using a specific permission request prefix to bypass per-resource access control. This allows the user to gain unauthorized access to all resources of that type within the same resource server, even if they do not have a ticket for those specific resources. This vulnerability requires the resource server to be configured in PERMISSIVE policy enforcement mode and affects typed resources with ownerManagedAccess enabled, where no explicit policy protects the resource type. The primary consequence is unauthorized information disclosure or modification of resources.
CVE-2026-11820 1 Redhat 1 Enterprise Linux 2026-07-01 N/A 6.5 MEDIUM
A flaw was found in the community.general Ansible collection's nexmo module. The module constructs HTTP requests to the Vonage/Nexmo SMS API by encoding API credentials (api_key and api_secret) into URL query parameters and sending them via GET requests. This causes credentials to be exposed in web server access logs, proxy logs, HTTP Referer headers, and network monitoring tools, despite the Ansible argument specification marking these parameters as no_log. An attacker with access to any of these logging or monitoring points can obtain the full API credentials and gain unauthorized access to the victim's Vonage/Nexmo account.
CVE-2026-12891 2 Gstreamer, Redhat 2 Gstreamer, Enterprise Linux 2026-07-01 N/A 4.3 MEDIUM
A flaw was found in the GStreamer gst-plugins-bad package. When processing a malformed H.266/VVC video stream with a crafted aspect ratio indicator value, the H.266 parser performs an out-of-bounds read of up to 8 bytes from adjacent memory. This flaw allows an attacker to craft a malicious H.266 video file or stream that, when processed by a GStreamer-based application, could leak limited memory contents through video metadata, potentially exposing sensitive information from the application's address space.
CVE-2026-9083 1 Redhat 1 Build Of Keycloak 2026-07-01 N/A 4.9 MEDIUM
A flaw was found in Keycloak. A realm administrator with the "manage-realm" role can exploit this vulnerability by submitting an arbitrary filesystem path as a keystore parameter when creating a key provider component. This allows the administrator to probe arbitrary filesystem paths, determining which files exist and are readable by the Keycloak process. This information disclosure could be used to identify high-value targets for follow-on attacks.
CVE-2025-62231 4 Debian, Ibm, Redhat and 1 more 11 Debian Linux, Aix, Vios and 8 more 2026-07-01 N/A 7.3 HIGH
A flaw was identified in the X.Org X server’s X Keyboard (Xkb) extension where improper bounds checking in the XkbSetCompatMap() function can cause an unsigned short overflow. If an attacker sends specially crafted input data, the value calculation may overflow, leading to memory corruption or a crash.
CVE-2025-62230 4 Debian, Ibm, Redhat and 1 more 11 Debian Linux, Aix, Vios and 8 more 2026-07-01 N/A 7.3 HIGH
A flaw was discovered in the X.Org X server’s X Keyboard (Xkb) extension when handling client resource cleanup. The software frees certain data structures without properly detaching related resources, leading to a use-after-free condition. This can cause memory corruption or a crash when affected clients disconnect.
CVE-2026-0989 3 Ibm, Redhat, Xmlsoft 7 Aix, Vios, Enterprise Linux and 4 more 2026-06-30 N/A 3.7 LOW
A flaw was identified in the RelaxNG parser of libxml2 related to how external schema inclusions are handled. The parser does not enforce a limit on inclusion depth when resolving nested <include> directives. Specially crafted or overly complex schemas can cause excessive recursion during parsing. This may lead to stack exhaustion and application crashes, creating a denial-of-service risk.
CVE-2026-0990 3 Ibm, Redhat, Xmlsoft 7 Aix, Vios, Enterprise Linux and 4 more 2026-06-30 N/A 5.9 MEDIUM
A flaw was found in libxml2, an XML parsing library. This uncontrolled recursion vulnerability occurs in the xmlCatalogXMLResolveURI function when an XML catalog contains a delegate URI entry that references itself. A remote attacker could exploit this configuration-dependent issue by providing a specially crafted XML catalog, leading to infinite recursion and call stack exhaustion. This ultimately results in a segmentation fault, causing a Denial of Service (DoS) by crashing affected applications.
CVE-2026-0992 3 Ibm, Redhat, Xmlsoft 7 Aix, Vios, Enterprise Linux and 4 more 2026-06-30 N/A 2.9 LOW
A flaw was found in the libxml2 library. This uncontrolled resource consumption vulnerability occurs when processing XML catalogs that contain repeated <nextCatalog> elements pointing to the same downstream catalog. A remote attacker can exploit this by supplying crafted catalogs, causing the parser to redundantly traverse catalog chains. This leads to excessive CPU consumption and degrades application availability, resulting in a denial-of-service condition.
CVE-2026-6732 3 Ibm, Redhat, Xmlsoft 7 Aix, Vios, Enterprise Linux and 4 more 2026-06-30 N/A 6.5 MEDIUM
A flaw was found in libxml2. This vulnerability occurs when the library processes a specially crafted XML Schema Definition (XSD) validated document that includes an internal entity reference. An attacker could exploit this by providing a malicious document, leading to a type confusion error that causes the application to crash. This results in a denial of service (DoS), making the affected system or application unavailable.
CVE-2026-12610 2 Fedoraproject, Redhat 2 Sssd, Enterprise Linux 2026-06-30 N/A 6.4 MEDIUM
A flaw was found in sssd. When authenticating with a YubiKey, the SSSD PAM responder can crash due to a use-after-free vulnerability, where a memory pointer is incorrectly handled. A local attacker could exploit this flaw by manipulating smartcard or YubiKey contents, leading to a denial of service that disrupts authentication. This vulnerability also presents a potential for privilege escalation, although it is difficult to exploit.
CVE-2026-11791 1 Redhat 3 389 Directory Server, Directory Server, Enterprise Linux 2026-06-30 N/A 5.0 MEDIUM
A flaw was found in 389 Directory Server. During schema reload, the attr_syntax_swap_ht() function unconditionally frees attribute syntax information nodes, bypassing the refcount-based deferred deletion used elsewhere in the attribute syntax subsystem. If an administrator triggers schema reload while concurrent LDAP query traffic is active, worker threads may access freed memory, resulting in use-after-free or double-free and a denial of service (server crash).
