| CVE-2026-5419 | 2 Gnu, Redhat | 14 Gnutls, Cert Manager, Discovery and 11 more | 2026-11-06 | 3.7 Low |
| A flaw was found in gnutls. The PKCS#7 padding check, performed during decryption, was not constant-time. This timing side-channel could allow a remote attacker to potentially leak sensitive information about the padding bytes through observable timing differences. This vulnerability is a form of information disclosure. | ||||
| CVE-2026-3832 | 2 Gnu, Redhat | 11 Gnutls, Cert Manager, Discovery and 8 more | 2026-11-06 | 3.7 Low |
| A flaw was found in gnutls. A remote attacker could exploit this vulnerability by presenting a specially crafted Online Certificate Status Protocol (OCSP) response during a TLS handshake. Due to a logic error in how gnutls processes multi-record OCSP responses, a client with OCSP verification enabled may incorrectly accept a revoked server certificate, potentially leading to a compromise of trust. | ||||
| CVE-2026-44605 | 1 Redhat | 5 Enterprise Linux, Hardened Images, Hummingbird and 2 more | 2026-11-06 | 5.5 Medium |
| A flaw was found in the RPM Package Manager (RPM). A local user could be affected by a heap buffer overflow vulnerability when processing a specially crafted NDB database file. This issue arises from an error in how RPM handles certain calculations during file parsing, leading to an incorrect memory allocation. An attacker could leverage this to cause a denial of service, making the system unavailable. | ||||
| CVE-2026-3633 | 3 Gnome, Libsoup, Redhat | 4 Libsoup, Libsoup, Enterprise Linux and 1 more | 2026-11-06 | 3.9 Low |
| A flaw was found in libsoup. A remote attacker, by controlling the method parameter of the `soup_message_new()` function, could inject arbitrary headers and additional request data. This vulnerability, known as CRLF (Carriage Return Line Feed) injection, occurs because the method value is not properly escaped during request line construction, potentially leading to HTTP request injection. | ||||
| CVE-2026-3632 | 3 Gnome, Libsoup, Redhat | 4 Libsoup, Libsoup, Enterprise Linux and 1 more | 2026-11-06 | 3.9 Low |
| A flaw was found in libsoup, a library used by applications to send network requests. This vulnerability occurs because libsoup does not properly validate hostnames, allowing special characters to be injected into HTTP headers. A remote attacker could exploit this to perform HTTP smuggling, where they can send hidden, malicious requests alongside legitimate ones. In certain situations, this could lead to Server-Side Request Forgery (SSRF), enabling an attacker to force the server to make unauthorized requests to other internal or external systems. The impact is low, as SoupServer is not actually used in internet infrastructure. | ||||
| CVE-2026-3234 | 2 Apache, Redhat | 3 Mod Proxy Cluster, Enterprise Linux, Jboss Core Services | 2026-11-06 | 4.3 Medium |
| A flaw was found in mod_proxy_cluster. This vulnerability, a Carriage Return Line Feed (CRLF) injection in the decodeenc() function, allows a remote attacker to bypass input validation. By injecting CRLF sequences into the cluster configuration, an attacker can corrupt the response body of INFO endpoint responses. Exploitation requires network access to the MCMP protocol port, but no authentication is needed. | ||||
| CVE-2026-3184 | 3 Kernel, Linux, Redhat | 7 Util-linux, Util-linux, Enterprise Linux and 4 more | 2026-11-06 | 3.7 Low |
| A flaw was found in util-linux. Improper hostname canonicalization in the `login(1)` utility, when invoked with the `-h` option, can modify the supplied remote hostname before setting `PAM_RHOST`. A remote attacker could exploit this by providing a specially crafted hostname, potentially bypassing host-based Pluggable Authentication Modules (PAM) access control rules that rely on fully qualified domain names. This could lead to unauthorized access. | ||||
| CVE-2026-28295 | 1 Redhat | 2 Enterprise Linux, Rhel Els | 2026-11-06 | 4.3 Medium |
| A flaw was found in the FTP GVfs backend. A malicious FTP server can exploit this vulnerability by providing an arbitrary IP address and port in its passive mode (PASV) response. The client unconditionally trusts this information and attempts to connect to the specified endpoint, allowing the malicious server to probe for open ports accessible from the client's network. | ||||
| CVE-2026-2340 | 2 Redhat, Samba | 11 Enterprise Linux, Enterprise Linux Eus, Openshift and 8 more | 2026-11-06 | 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-2026-2708 | 3 Gnome, Libsoup, Redhat | 4 Libsoup, Libsoup, Enterprise Linux and 1 more | 2026-11-06 | 3.7 Low |
| A request smuggling vulnerability exists in libsoup's HTTP/1 header parsing logic. The soup_message_headers_append_common() function in libsoup/soup-message-headers.c unconditionally appends each header value without validating for duplicate or conflicting Content-Length fields. This allows an attacker to send HTTP requests containing multiple Content-Length headers with differing values. | ||||
| CVE-2026-9797 | 2 Red Hat, Redhat | 3 Red Hat Build Of Keycloak 26.4, Build Keycloak, Build Of Keycloak | 2026-11-06 | 6.5 Medium |
| A flaw was found in Keycloak's administrative services (org.keycloak.services.resources.admin). A highly privileged attacker, authenticated with a 'manage-clients' role, could exploit this vulnerability through several methods, including manipulating client JSON Web Key Sets (JWKS), swapping client authenticator types and resetting secrets, or downloading legitimate signing keys. Successful exploitation allows the attacker to obtain a token with 'realm-admin' role assignments, leading to privilege escalation and potential unauthorized access to sensitive resources. | ||||
| CVE-2026-97367 | 1 Redhat | 2 Build Keycloak, Red Hat Single Sign On | 2026-11-06 | 6.4 Medium |
| A flaw was found in the Keycloak Account REST API where it incorrectly handles session identification. A malicious client owner can manipulate their own security tokens to point to a different user's active session. This allows the attacker to access and modify the victim's account information, potentially leading to a full account takeover by changing the recovery email and resetting the password. | ||||
| CVE-2026-96447 | 1 Redhat | 2 Build Keycloak, Red Hat Single Sign On | 2026-11-06 | 4.2 Medium |
| A flaw was found in the TokenManager component of Keycloak, an open-source identity and access management solution. The issue occurs during the validation of stateless access tokens when the original user ID no longer exists. Keycloak incorrectly falls back to using the username to identify the user without verifying if the identity matches the original token subject. This could allow an attacker with an old token to gain access to a newly created service account if it shares the same client ID as a previously deleted one. | ||||
| CVE-2026-19688 | 1 Redhat | 2 Build Keycloak, Red Hat Single Sign On | 2026-11-06 | 6.8 Medium |
| A flaw was found in the Admin REST API of Keycloak, an identity and access management solution. The Admin API fails to verify the intended audience of bearer tokens during authentication. This issue allows an attacker who operates a client within a realm to capture an administrator's access token and reuse it to perform unauthorized administrative actions, potentially leading to full realm compromise. | ||||
| CVE-2026-19608 | 1 Redhat | 4 Build Keycloak, Build Of Keycloak, Red Hat Single Sign On and 1 more | 2026-11-06 | 5.3 Medium |
| A flaw was found in the group policy provider of Keycloak authorization services, which is used to manage fine-grained access control to resources. The issue occurs when the system evaluates group-based policies using tokens that only contain group names rather than full paths. If two groups in different parts of the organization share the same name, a user in the unauthorized group can be mistaken for a member of the authorized group. This can allow a user to gain unauthorized access to protected resources they should not be able to reach. | ||||
| CVE-2026-15713 | 2 Libsoup, Redhat | 3 Libsoup, Enterprise Linux, Rhel Els | 2026-11-06 | 5.9 Medium |
| A vulnerability was found in libsoup's HTTP/2 protocol implementation. The library fails to correctly release memory context blocks under specific stream termination conditions, such as when an HTTP/2 connection encounters window exhaustion or explicit stream resets. A remote, unauthenticated attacker acting as a malicious network peer can trick the connection engine into allocating stream states that are subsequently leaked during cleanup. Over a sustained period, this flaw allows the remote attacker to consume the system's heap allocations incrementally, triggering a denial of service (DoS) through an ultimate Out-of-Memory (OOM) application crash. | ||||
| CVE-2026-114232 | 2 Red Hat, Redhat | 5 Red Hat Build Of Keycloak 26.4, Build Keycloak, Build Of Keycloak and 2 more | 2026-11-06 | 8.1 High |
| A flaw was found in the UserManagedPermissionService of the Keycloak authorization server. The UMA Protection API, which manages user permissions, fails to validate the resourceType field when a user creates a new policy. This allows an attacker to create a policy that applies to resources owned by other users, potentially leading to unauthorized access or modification of sensitive data across the entire realm. | ||||
| CVE-2026-110932 | 2 Red Hat, Redhat | 5 Red Hat Build Of Keycloak 26.4, Build Keycloak, Build Of Keycloak and 2 more | 2026-11-06 | 7.5 High |
| A flaw was found in the theme resource endpoint of Keycloak, an open-source identity and access management solution. The issue occurs because the server fails to validate theme names before using them as keys for an on-disk gzip cache. An unauthenticated attacker can exploit this by sending many requests with unique, fabricated theme names, leading to persistent disk space exhaustion that survives server restarts and causes service disruptions. | ||||
| CVE-2025-4476 | 1 Redhat | 2 Enterprise Linux, Rhel Els | 2026-11-06 | 4.3 Medium |
| A denial-of-service vulnerability has been identified in the libsoup HTTP client library. This flaw can be triggered when a libsoup client receives a 401 (Unauthorized) HTTP response containing a specifically crafted domain parameter within the WWW-Authenticate header. Processing this malformed header can lead to a crash of the client application using libsoup. An attacker could exploit this by setting up a malicious HTTP server. If a user's application using the vulnerable libsoup library connects to this malicious server, it could result in a denial-of-service. Successful exploitation requires tricking a user's client application into connecting to the attacker's malicious server. | ||||
| CVE-2026-2443 | 3 Gnome, Red Hat, Redhat | 4 Libsoup, Enterprise Linux, Enterprise Linux and 1 more | 2026-11-06 | 5.3 Medium |
| A flaw was identified in libsoup, a widely used HTTP library in GNOME-based systems. When processing specially crafted HTTP Range headers, the library may improperly validate requested byte ranges. In certain build configurations, this could allow a remote attacker to access portions of server memory beyond the intended response. Exploitation requires a vulnerable configuration and access to a server using the embedded SoupServer component. | ||||
