CVE-2026-2575 2 Keycloak, Redhat 4 Keycloak, Build Keycloak, Build Of Keycloak and 1 more 2026-09-29 5.3 Medium
A flaw was found in Keycloak. An unauthenticated remote attacker can trigger an application level Denial of Service (DoS) by sending a highly compressed SAMLRequest through the SAML Redirect Binding. The server fails to enforce size limits during DEFLATE decompression, leading to an OutOfMemoryError (OOM) and subsequent process termination. This vulnerability allows an attacker to disrupt the availability of the service.
CVE-2026-7507 1 Redhat 3 Build Keycloak, Build Of Keycloak, Red Hat Single Sign On 2026-09-29 7.5 High
A session fixation vulnerability was found in Keycloak's login-actions endpoints. An unauthenticated attacker could exploit this flaw by pre-creating an authentication session and tricking a victim into visiting a maliciously crafted link. By leveraging the /login-actions/restart endpoint—which processes session handles without adequate CSRF protection or cookie ownership validation—an attacker can reset the authentication flow state. This causes Single Sign-On (SSO) to authenticate the victim transparently upon clicking the link, allowing the attacker to hijack the required-action form without needing the victim's credentials. A successful exploit could lead to complete account takeover, including highly privileged administrative accounts.
CVE-2026-7307 1 Redhat 3 Build Keycloak, Build Of Keycloak, Red Hat Single Sign On 2026-09-29 7.5 High
A flaw was found in Keycloak. A remote, unauthenticated attacker can send a specially crafted XML input to the Security Assertion Markup Language (SAML) endpoint. This malicious input can cause high CPU usage and worker thread starvation, leading to a Denial of Service (DoS) where the server becomes unavailable.
CVE-2026-4634 1 Redhat 3 Build Keycloak, Build Of Keycloak, Red Hat Single Sign On 2026-09-29 7.5 High
A flaw was found in Keycloak. An unauthenticated attacker can exploit this vulnerability by sending a specially crafted POST request with an excessively long scope parameter to the OpenID Connect (OIDC) token endpoint. This leads to high resource consumption and prolonged processing times, ultimately resulting in a Denial of Service (DoS) for the Keycloak server.
CVE-2026-2092 1 Redhat 3 Build Keycloak, Build Of Keycloak, Red Hat Single Sign On 2026-09-29 7.7 High
A flaw was found in Keycloak. Keycloak's Security Assertion Markup Language (SAML) broker endpoint does not properly validate encrypted assertions when the overall SAML response is not signed. An attacker with a valid signed SAML assertion can exploit this by crafting a malicious SAML response. This allows the attacker to inject an encrypted assertion for an arbitrary principal, leading to unauthorized access and potential information disclosure.
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-2026-87114 1 Redhat 4 Openshift, Openshift Container Platform, Pdrive Lightspeed and 1 more 2026-09-29 7.1 High
A flaw was found in kube-compare. When processing a 'container://' reference path, the tool incorrectly executes an untrusted container image's entrypoint instead of merely extracting data from a stopped container. This allows a remote attacker to achieve arbitrary code execution on the operator's workstation. If the Docker daemon requires elevated privileges, the untrusted code may execute with root-mediated daemon privileges, posing a significant security risk.
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-2026-102010 2 Gnu, Redhat 6 Gcc, Enterprise Linux, Hardened Images and 3 more 2026-09-29 7 High
A flaw was found in GCC. When an application calls the erase_if function on a binary heap priority queue in libstdc++, the library reallocates storage but fails to update its internal entry pointer. An attacker capable of triggering this operation can exploit this use-after-free condition, leading to a Denial of Service (DoS) via an application crash or potential memory corruption.
CVE-2026-97025 2 Flatpak, Redhat 2 Flatpak, Enterprise Linux 2026-09-29 3.2 Low
Flatpak writes the OCI repository authentication token with world-readable permissions (0644) in the system-helper's cache directory, allowing other local users on a multi-user system to read the token and impersonate the authenticated user against the OCI repository. Only OCI-based sources (e.g. as used by Fedora) are affected; libostree-based sources such as Flathub are not.
CVE-2026-97026 2 Flatpak, Redhat 2 Flatpak, Enterprise Linux 2026-09-29 3.9 Low
Flatpak creates temporary child repository directories under the user cache with world-writable permissions (0777). On multi-user systems with a permissive umask, other local users could read or modify the temporary directory used while installing apps or runtimes, potentially causing installation failures (denial of service); tampered content would fail signature/digest verification rather than being trusted.
CVE-2026-97027 2 Flatpak, Redhat 2 Flatpak, Enterprise Linux 2026-09-29 3.6 Low
Flatpak passes through arbitrary vendor-extension keys unmodified when exporting an application's Desktop Entry (.desktop) and D-Bus Service (.service) files, instead of validating against an allowlist. A malicious Flatpak app can use this to cause denial of service (e.g. forced application restart loops) or to influence host D-Bus/systemd activation behavior beyond what the sandbox is intended to permit.
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-2026-101292 1 Redhat 3 Amq Broker, Amq Broker 7, Jboss Enterprise Application Platform 2026-09-29 8.2 High
Apache ActiveMQ Artemis before 2.34.0 contains an unsafe reflection vulnerability in FederationStreamConnectMessage.getFederationPolicy(). The method calls Class.forName(clazz).getConstructor().newInstance() where clazz is read directly from the CORE protocol wire buffer without type validation. An authenticated federation peer can send a FEDERATION_DOWNSTREAM_CONNECT packet with a crafted class name, causing the broker to load and instantiate arbitrary classes visible to the Artemis module classloader. Static initializers (<clinit>) and no-argument constructors (<init>()) execute as side effects before the type cast, enabling denial of service via system-property poisoning, out-of-memory conditions via classloading, or broker state manipulation.
CVE-2026-15143 2 Red Hat, Redhat 2 Red Hat Openshift Ai (rhoai), Openshift Ai 2026-09-29 9.3 Critical
A flaw was found in the file_type content detector of guardrails-detectors. This vulnerability allows a remote attacker to supply an arbitrary XML Schema Definition (XSD) string, which is processed without proper restrictions. This can lead to server-side requests to arbitrary URLs or local file reads, potentially resulting in sensitive information disclosure, such as cloud provider credentials or access to internal network services.
CVE-2026-102474 1 Redhat 1 Enterprise Linux 2026-09-29 4 Medium
A flaw was found in dash. The printf builtin reserves four bytes before converting a Unicode \u or \U escape, but the multi-byte token can need five or six bytes. A local user who can supply such an escape to dash printf or echo %b, including through dash -c and a positional argument, can write one or two bytes past that reservation.
CVE-2026-102473 1 Redhat 1 Enterprise Linux 2026-09-29 5.5 Medium
A flaw was found in dash. When built without libc fnmatch, the internal pmatch() matcher implements * by unbounded recursion over candidate positions. A local user who can plant filenames, or otherwise feed that matcher, can make a short multi-star pattern such as *.*.*.*.*.tar.gz consume excessive CPU.
CVE-2023-6394 2 Quarkus, Redhat 3 Quarkus, Build Of Quarkus, Quarkus 2026-09-29 7.4 High
A flaw was found in Quarkus. This issue occurs when receiving a request over websocket with no role-based permission specified on the GraphQL operation, Quarkus processes the request without authentication despite the endpoint being secured. This can allow an attacker to access information and functionality outside of normal granted API permissions.
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.
