| CVE-2026-92248 | 1 Redhat | 3 Enterprise Linux, Rhel E4s, Rhel Els | 2026-11-05 | 7.8 High |
| A flaw was found in the file-psd plugin in GIMP. When generating a thumbnail preview for a specially crafted PSD (Photoshop Document) image file, an integer overflow occurs during the multiplication of values from an embedded JPEG header. This leads to an undersized heap allocation, resulting in a heap-based buffer overflow when the image data is decoded. This buffer overflow corrupts adjacent heap objects, allowing for a controlled memory write that can result in an application crash or arbitrary code execution. | ||||
| CVE-2026-91149 | 1 Redhat | 4 Enterprise Linux, Openshift Dev Spaces, Openshift Devspaces and 1 more | 2026-11-05 | 7.5 High |
| A flaw was found in Cockpit. An unauthenticated remote attacker can exploit this vulnerability by initiating and sustaining numerous simultaneous connections to the `cockpit-tls` service. This forces the service to create an unbounded number of detached threads, consuming system resources such as memory and file descriptors. The primary consequence is a denial of service (DoS), leading to degradation or complete unavailability of the Cockpit service for legitimate users. | ||||
| CVE-2026-90949 | 1 Redhat | 2 Enterprise Linux, Rhel Els | 2026-11-05 | 7.8 High |
| A flaw was found in GIMP's PSP (Paint Shop Pro) file loader. When processing a compressed selection channel, a heap-based buffer overflow can occur due to a mismatch between the allocated buffer size and the amount of data decompressed. A remote attacker could exploit this vulnerability by crafting a malicious PSP file. Opening this file in GIMP could lead to a crash or arbitrary code execution. | ||||
| CVE-2026-90948 | 1 Redhat | 3 Enterprise Linux, Rhel E4s, Rhel Els | 2026-11-05 | 7.8 High |
| A flaw was found in GIMP's ICO file loader. When processing an ICO file containing an embedded PNG image, an integer overflow can occur during the calculation of the required buffer size. This leads to an undersized buffer being allocated, causing a heap-based buffer overflow when the decoded pixel data is written. A remote attacker could exploit this by crafting a malicious ICO file, which, when opened, could lead to arbitrary code execution or a crash. | ||||
| CVE-2026-90947 | 1 Redhat | 3 Enterprise Linux, Rhel E4s, Rhel Els | 2026-11-05 | 7.8 High |
| A flaw was found in GIMP. When processing a specially crafted lighting preset file, the Lighting Effects filter does not properly validate the number of light sources. This can lead to an out-of-bounds write, corrupting memory. An attacker could exploit this by convincing a user to open a malicious preset file, potentially causing a crash or enabling arbitrary code execution. | ||||
| CVE-2026-9064 | 1 Redhat | 12 389 Directory Server, Directory Server, Directory Server E4s and 9 more | 2026-11-05 | 7.5 High |
| A flaw was found in 389-ds-base. The get_ldapmessage_controls_ext() function in the LDAP server does not enforce an upper bound on the number of controls per LDAP message. A remote, unauthenticated attacker can send a specially crafted LDAP request containing hundreds of thousands of minimal controls within the default maximum BER message size (2 MB), causing excessive CPU consumption and heap allocation on the server. Under concurrent exploitation, this leads to significant latency degradation, worker thread starvation, or out-of-memory termination, resulting in a denial of service. | ||||
| CVE-2026-108949 | 1 Apache | 2 Activemq, Activemq Broker | 2026-11-05 | 6.5 Medium |
| Denial of Service via OOM vulnerability in Apache ActiveMQ, ActiveMQ Broker. An authenticated OpenWire client that sends a ConsumerInfo for a temporary queue/topic owned by another connection is rejected with InvalidDestinationException, but the rejected Subscription is left behind in the region's subscriptions map. Repeating the request leaks broker heap until OOM because the broker does not clean up the rejected subscriptions in the map. This issue affects Apache ActiveMQ: from 6.0.0 before 6.3.3, before 5.19.12; ActiveMQ Broker: from 6.0.0 before 6.3.3, before 5.19.12. Users are recommended to upgrade to version 6.4.0, 6.3.3, or 5.19.12, which fixes the issue. | ||||
| CVE-2026-97848 | 2026-11-05 | 6.5 Medium | ||
| A flaw was found in the token sanitization logic of Keycloak, an open source identity and access management solution. The issue occurs when a protocol mapper is configured to emit structured claims using the JSON type. The security check designed to remove unauthorized role mappings only looks for standard Java maps and fails to recognize Jackson based JSON objects. This allows an attacker to inject forged client roles into security tokens, which could lead to unauthorized access to protected resources. | ||||
| CVE-2026-97367 | 2026-11-05 | 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-2026-96547 | 2026-11-05 | 6.5 Medium | ||
| A flaw was found in the Dynamic Client Registration component of Keycloak, an open-source identity and access management solution. The issue occurs because the system does not properly restrict which claim names can be used when setting up new clients. An attacker with valid registration credentials could create a client that incorrectly maps standard user profile information to sensitive security roles, potentially allowing them to gain unauthorized privileges on external applications that trust Keycloak tokens. | ||||
| CVE-2026-96460 | 2026-11-05 | 5.4 Medium | ||
| A flaw was found in the token exchange mechanism of Keycloak. When using Standard Token Exchange V2, the system issues new tokens with a fresh lifetime based on the requester clients configuration instead of limiting it to the original tokens expiration. This issue allows an authenticated requester to indefinitely extend access for service accounts by repeatedly exchanging tokens, even if the original client has been disabled by an administrator. | ||||
| CVE-2026-96447 | 2026-11-05 | 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-2026-92856 | 2026-11-05 | 4.9 Medium | ||
| A flaw was found in the SAML brokering component of Keycloak, an identity and access management solution. The issue occurs when Keycloak acts as an intermediary between an upstream identity provider and downstream services. Keycloak fails to respect specific security instructions called ProxyRestrictions in the login messages it receives. This allows a user to log into downstream services even when the original identity provider explicitly forbade further sharing of the login session. As a result, users can bypass security boundaries intended to limit where their identity can be used. | ||||
| CVE-2026-19688 | 2026-11-05 | 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-2026-107124 | 2026-11-05 | 6.4 Medium | ||
| A flaw was found in the OIDC logout endpoint of the keycloak-services component, which handles user session termination in Red Hat Build of Keycloak. The issue occurs because the system sets a session cookie based on an unvalidated token hint before completing security checks. An attacker can use this flaw to fix a session ID in a victim's browser, allowing them to hijack the victim's subsequent login and gain full control over their account. | ||||
| CVE-2026-109081 | 2026-11-05 | 6.8 Medium | ||
| A flaw was found in Keycloak. The Dynamic Client Registration (DCR) endpoint does not properly validate authorization when processing the deprecated defaultRoles field. An authenticated attacker with client creation privileges or an Initial Access Token (IAT) can inject excessive roles into the realm's default roles configuration. This causes clients across the realm to generate bloated access tokens, resulting in performance and memory degradation that can lead to a Denial of Service (DoS). | ||||
| CVE-2026-121837 | 2026-11-05 | 4.3 Medium | ||
| A flaw was found in the REST Data Panache component of Quarkus. When a security constraint is applied to an entity property using the @SecureField annotation on its getter method rather than the field itself, the generated REST resource fails to enforce this constraint for filtering and sorting operations. This allows an authenticated user to infer sensitive data values by observing which records match specific filter criteria or how they are ordered, even though the values are omitted from the final response. | ||||
| CVE-2026-89091 | 1 Redhat | 14 Acm, Ansible Automation Platform, Ansible Core and 11 more | 2026-11-04 | 8.8 High |
| A flaw was found in ansible-core. When installing a collection with `ansible-galaxy collection install`, the archive extractor validates member paths using lexical path normalisation (os.path.abspath) instead of resolving symbolic links (os.path.realpath), and it performs no containment check on symlink-typed directory members before creating them. A crafted collection tarball can chain symlink directory entries so that a subsequent file member is written outside the intended destination directory. This allows an attacker who can get a victim to install a malicious collection to overwrite arbitrary files with the privileges of the user running ansible-galaxy, leading to code execution on the control node. This is a bypass of the fix for CVE-2020-10691. | ||||
| CVE-2026-88924 | 2 Gnome, Redhat | 6 Gvfs, Enterprise Linux, Enterprise Linux Eus and 3 more | 2026-11-04 | 7 High |
| A flaw was found in the admin backend of gvfs. The privileged gvfsd-admin daemon changes the ownership of newly created private D-Bus sockets by calling the link-following chown() function on a pathname inside a user-controlled directory. A local attacker can exploit this via a Time-of-Check Time-of-Use (TOCTOU) race condition and exchange the socket pathname with a symbolic link pointing to an arbitrary root-owned file (such as /etc/pam.d/su). The daemon subsequently follows the symlink and changes the ownership of the targeted root-owned file to the attacker's user ID. This allows an authenticated local attacker to modify critical system files, leading to a full local privilege escalation to root. | ||||
| CVE-2026-86848 | 1 Redhat | 3 Enterprise Linux, Openshift, Openstack | 2026-11-04 | 8.8 High |
| A flaw was found in DPDK lib/vhost vhost-crypto. The indirect-descriptor snapshot double-fetches a guest descriptor next index, allowing a malicious guest to cause an out-of-bounds access in the host backend. | ||||
