CVE-2026-18203 1 Redhat 1 Build Of Keycloak 2026-08-07 N/A 6.5 MEDIUM
A flaw was found in the group policy evaluation logic of Keycloak, an identity and access management solution. When a group policy is set to extend permissions to child groups, the system incorrectly uses a simple text-based prefix check to verify group membership. This allows a user who belongs to a different group with a similar starting name to bypass security checks and gain unauthorized access to administrative functions or protected resources.
CVE-2026-18206 1 Redhat 1 Build Of Keycloak 2026-08-07 N/A 3.7 LOW
A flaw was found in the keycloak-services component of Keycloak, which provides identity and access management services. The issue occurs when a realm administrator uses a wildcard domain (like *.example.com) to restrict which hosts can register or update clients. Due to improper validation, the system accepts any hostname that ends with the specified domain suffix, even if it is not a legitimate subdomain. An attacker who can control the reverse DNS of their connection can bypass these host-based restrictions, potentially allowing unauthorized client modifications.
CVE-2026-18208 1 Redhat 1 Build Of Keycloak 2026-08-07 N/A 6.5 MEDIUM
A flaw was found in the OIDC token introspection endpoint of the keycloak-services component. Keycloak is an open-source identity and access management solution used to secure modern applications and services. The issue occurs when a confidential client, configured to receive signed JWT introspection responses, attempts to introspect a token issued for a different audience. Although the endpoint correctly identifies the token as inactive for that client, it still returns the full set of token claims within a signed JWT field. This allows an unauthorized client to bypass audience-based restrictions and access sensitive information contained in the token.
CVE-2026-18211 1 Redhat 1 Build Of Keycloak 2026-08-07 N/A 4.2 MEDIUM
A flaw was found in the secure-client-uris client policy executor within Keycloak core services. This component is responsible for enforcing security requirements on client configurations, such as requiring encrypted connections for redirect URIs. Due to an improper check that only looks at the start of a web address rather than properly verifying the host, an attacker can bypass these security restrictions by using a specially crafted domain name. This could allow an attacker to intercept sensitive authentication codes over unencrypted connections.
CVE-2025-4374 1 Redhat 1 Quay 2026-08-07 N/A 6.5 MEDIUM
A flaw was found in Quay. When an organization acts as a proxy cache, and a user or robot pulls an image that hasn't been mirrored yet, they are granted "Admin" permissions on the newly created repository.
CVE-2026-11793 1 Redhat 1 389 Directory Server 2026-08-07 N/A 4.9 MEDIUM
A stack buffer overflow flaw was found in 389 Directory Server. The checkPrefix() function in pw.c copies an attacker-controlled algorithm ID into a 256-byte stack buffer without bounds checking when parsing reversible-encrypted attribute values. An attacker with Directory Manager privileges can crash the LDAP server by storing a crafted credential with an oversized algorithm ID. FORTIFY_SOURCE mitigates this to denial of service only.
CVE-2023-46847 2 Redhat, Squid-cache 10 Enterprise Linux, Enterprise Linux Eus, Enterprise Linux For Arm 64 and 7 more 2026-08-07 N/A 8.6 HIGH
Squid is vulnerable to a Denial of Service, where a remote attacker can perform buffer overflow attack by writing up to 2 MB of arbitrary data to heap memory when Squid is configured to accept HTTP Digest Authentication.
CVE-2024-1488 2 Fedoraproject, Redhat 19 Unbound, Codeready Linux Builder, Codeready Linux Builder Eus and 16 more 2026-08-06 N/A 8.0 HIGH
A vulnerability was found in Unbound due to incorrect default permissions, allowing any process outside the unbound group to modify the unbound runtime configuration. If a process can connect over localhost to port 8953, it can alter the configuration of unbound.service. This flaw allows an unprivileged attacker to manipulate a running instance, potentially altering forwarders, allowing them to track all queries forwarded by the local resolver, and, in some cases, disrupting resolving altogether.
CVE-2024-0646 2 Linux, Redhat 2 Linux Kernel, Enterprise Linux 2026-08-06 N/A 7.0 HIGH
An out-of-bounds memory write flaw was found in the Linux kernel’s Transport Layer Security functionality in how a user calls a function splice with a ktls socket as the destination. This flaw allows a local user to crash or potentially escalate their privileges on the system.
CVE-2023-6546 3 Fedoraproject, Linux, Redhat 3 Fedora, Linux Kernel, Enterprise Linux 2026-08-06 N/A 7.0 HIGH
A race condition was found in the GSM 0710 tty multiplexor in the Linux kernel. This issue occurs when two threads execute the GSMIOC_SETCONF ioctl on the same tty file descriptor with the gsm line discipline enabled, and can lead to a use-after-free problem on a struct gsm_dlci while restarting the gsm mux. This could allow a local unprivileged user to escalate their privileges on the system.
CVE-2023-6531 2 Linux, Redhat 2 Linux Kernel, Enterprise Linux 2026-08-06 N/A 7.0 HIGH
A use-after-free flaw was found in the Linux Kernel due to a race problem in the unix garbage collector's deletion of SKB races with unix_stream_read_generic() on the socket that the SKB is queued on.
CVE-2023-5090 2 Linux, Redhat 2 Linux Kernel, Enterprise Linux 2026-08-06 N/A 6.0 MEDIUM
A flaw was found in KVM. An improper check in svm_set_x2apic_msr_interception() may allow direct access to host x2apic msrs when the guest resets its apic, potentially leading to a denial of service condition.
CVE-2023-3384 1 Redhat 1 Quay 2026-08-06 N/A 5.4 MEDIUM
A flaw was found in the Quay registry. While the image labels created through Quay undergo validation both in the UI and backend by applying a regex (validation.py), the same validation is not performed when the label comes from an image. This flaw allows an attacker to publish a malicious image to a public registry containing a script that can be executed via Cross-site scripting (XSS).
CVE-2021-40438 11 Apache, Broadcom, Debian and 8 more 40 Http Server, Brocade Fabric Operating System Firmware, Debian Linux and 37 more 2026-08-06 6.8 MEDIUM 9.0 CRITICAL
A crafted request uri-path can cause mod_proxy to forward the request to an origin server choosen by the remote user. This issue affects Apache HTTP Server 2.4.48 and earlier.
CVE-2017-12615 4 Apache, Microsoft, Netapp and 1 more 23 Tomcat, Windows, 7-mode Transition Tool and 20 more 2026-08-06 6.8 MEDIUM 8.1 HIGH
When running Apache Tomcat 7.0.0 to 7.0.79 on Windows with HTTP PUTs enabled (e.g. via setting the readonly initialisation parameter of the Default to false) it was possible to upload a JSP file to the server via a specially crafted request. This JSP could then be requested and any code it contained would be executed by the server.
CVE-2012-4681 2 Oracle, Redhat 6 Jdk, Jre, Enterprise Linux Desktop and 3 more 2026-08-06 10.0 HIGH 9.8 CRITICAL
Multiple vulnerabilities in the Java Runtime Environment (JRE) component in Oracle Java SE 7 Update 6 and earlier allow remote attackers to execute arbitrary code via a crafted applet that bypasses SecurityManager restrictions by (1) using com.sun.beans.finder.ClassFinder.findClass and leveraging an exception with the forName method to access restricted classes from arbitrary packages such as sun.awt.SunToolkit, then (2) using "reflection with a trusted immediate caller" to leverage the getField method to access and modify private fields, as exploited in the wild in August 2012 using Gondzz.class and Gondvv.class.
CVE-2012-1723 2 Oracle, Redhat 8 Jdk, Jre, Enterprise Linux Desktop and 5 more 2026-08-06 10.0 HIGH 9.8 CRITICAL
Unspecified vulnerability in the Java Runtime Environment (JRE) component in Oracle Java SE 7 update 4 and earlier, 6 update 32 and earlier, 5 update 35 and earlier, and 1.4.2_37 and earlier allows remote attackers to affect confidentiality, integrity, and availability via unknown vectors related to Hotspot.
CVE-2022-1353 4 Debian, Linux, Netapp and 1 more 19 Debian Linux, Linux Kernel, H300e and 16 more 2026-08-05 3.6 LOW 7.1 HIGH
A vulnerability was found in the pfkey_register function in net/key/af_key.c in the Linux kernel. This flaw allows a local, unprivileged user to gain access to kernel memory, leading to a system crash or a leak of internal kernel information.
CVE-2021-3501 4 Fedoraproject, Linux, Netapp and 1 more 27 Fedora, Linux Kernel, Cloud Backup and 24 more 2026-08-05 3.6 LOW 7.1 HIGH
A flaw was found in the Linux kernel in versions before 5.12. The value of internal.ndata, in the KVM API, is mapped to an array index, which can be updated by a user process at anytime which could lead to an out-of-bounds write. The highest threat from this vulnerability is to data integrity and system availability.
CVE-2026-14209 1 Redhat 2 Build Of Keycloak, Jboss Enterprise Application Platform Expansion Pack 2026-08-05 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.
