CVE-2026-117859

Keycloak-services: keycloak-services: par single-use bypass via flow restart

A flaw was found in the Pushed Authorization Request PAR implementation of the keycloak-services component. The issue occurs when an authentication flow is restarted, which incorrectly clears the internal markers used to track PAR consumption while leaving the request active. This allows an attacker to reuse the same authorization request to obtain multiple access tokens, bypassing security requirements for single-use requests.

Quarkus-vertx-http: authorization bypass via path normalization discrepancy in quarkus http security

A flaw was found in Quarkus HTTP security. An unauthenticated attacker can exploit a discrepancy in how paths are normalized between the security matcher and HTTP request dispatchers. This allows the attacker to craft a URL that the security matcher considers public, but which is then routed to a protected endpoint, leading to an authorization bypass and potential unauthorized access to sensitive information.

net: skbuff: preserve shared-frag marker during coalescing

In the Linux kernel, the following vulnerability has been resolved: net: skbuff: preserve shared-frag marker during coalescing skb_try_coalesce() can attach paged frags from @from to @to. If @from has SKBFL_SHARED_FRAG set, the resulting @to skb can contain the same externally-owned or page-cache-backed frags, but the shared-frag marker is currently lost. That breaks the invariant relied on by later in-place writers. In particular, ESP input checks skb_has_shared_frag() before deciding whether an uncloned nonlinear skb can skip skb_cow_data(). If TCP receive coalescing has moved shared frags into an unmarked skb, ESP can see skb_has_shared_frag() as false and decrypt in place over page-cache backed frags. Propagate SKBFL_SHARED_FRAG when skb_try_coalesce() transfers paged frags. The tailroom copy path does not need the marker because it copies bytes into @to's linear data rather than transferring frag descriptors.

Apache CXF: XML External Entity (XXE) Injection in W3CMultiSchemaFactory and EndpointReferenceUtils

Apache CXF's EndpointReferenceUtils and W3CMultiSchemaFactory classes construct a SAXParserFactory without the necessary JAXP hardening configurations, enabling out-of-band (OOB) external entity resolution. Users are recommended to upgrade to versions 4.2.2 or 4.1.7 or 3.6.12, which fix this issue.

Keycloak: keycloak: information disclosure via oidc token introspection endpoint audience bypass

A flaw was found in Keycloak. This access control vulnerability in Keycloak's OpenID Connect (OIDC) token introspection endpoint allows a confidential client to bypass audience restrictions. An attacker-controlled client with valid credentials can retrieve sensitive token claims intended for other resource servers, compromising the confidentiality of lightweight access tokens. This issue can be exploited remotely by any confidential client in the realm with valid credentials.

Openstack-network-exporter: http.server has no readheadertimeout / readtimeout (slowloris)

A flaw was found in openstack-network-exporter. The HTTP server within the component is configured without essential timeout settings, such as ReadHeaderTimeout. This vulnerability allows an unauthenticated, remote attacker to initiate multiple slow HTTP header connections. By trickling header bytes, the attacker can exhaust server resources, specifically file descriptors, leading to a Denial of Service (DoS) that prevents legitimate Prometheus metric scraping and alerting.

Keycloak-services: keycloak-services: required otp enrollment bypassed via update user locale required action ordering

A flaw was found in the Update User Locale required action of the Keycloak identity and access management solution. When this action is ordered before the Configure OTP action in a realm, the system may fail to enforce mandatory multi-factor authentication enrollment during the login process. This issue allows an attacker with a valid password to access an account without setting up the required one-time password (OTP) credential.

Dracut: dracut: root code execution via dhcp options command injection

A flaw was found in dracut. A remote attacker on the adjacent network can exploit this vulnerability by providing specially crafted DHCP (Dynamic Host Configuration Protocol) options, such as a malicious hostname, to a system using dracut's legacy DHCP path. These options are improperly handled and written into temporary shell scripts without proper escaping, leading to command injection. This allows the attacker to achieve root code execution within the initramfs, potentially compromising the system's boot and network behavior.

maclof kubernetes-client 0.17.0 before 0.32.0 disables TLS certificate verification in parseKubeconfig() and parseKubeconfigFile() when a kubeconfig lacks certificate-authority-data, ignoring insecure-skip-tls-verify. On-path attackers can impersonate the Kubernetes API server to capture Bearer tokens or Basic credentials and tamper with WebSocket or REST API traffic.

Openstack-network-exporter: basic-auth uses plaintext password storage and non-constant-time comparison

A flaw was found in openstack-network-exporter. When an operator configures user authentication but omits or misconfigures Transport Layer Security (TLS), the basic authentication mechanism is silently bypassed. This fail-open design allows an adjacent network attacker to access sensitive Open vSwitch (OVS) and Open Virtual Network (OVN) dataplane metrics without credentials. Consequently, an attacker can enumerate bridge names, port counters, OVN controller state, and host topology, leading to information disclosure.

jq: Out-of-Bounds Read in jv_parse_sized() Error Formatting for Non-NUL-Terminated Counted Buffers

jq is a command-line JSON processor. In commits before 2f09060afab23fe9390cce7cb860b10416e1bf5f, the jv_parse_sized() API in libjq accepts a counted buffer with an explicit length parameter, but its error-handling path formats the input buffer using %s in jv_string_fmt(), which reads until a NUL terminator is found rather than respecting the caller-supplied length. This means that when malformed JSON is passed in a non-NUL-terminated buffer, the error construction logic performs an out-of-bounds read past the end of the buffer. The vulnerability is reachable by any libjq consumer calling jv_parse_sized() with untrusted input, and depending on memory layout, can result in memory disclosure or process termination. The issue has been patched in commit 2f09060afab23fe9390cce7cb860b10416e1bf5f.

Trustyai-service-operator: trustyai service operator: unauthenticated access to ai guardrails and orchestrator apis

A flaw was found in the TrustyAI Service Operator. When deploying services like gorch or NemoGuardrails, if a specific security setting is not enabled, these services can expose their communication channels without requiring users to prove their identity. This allows any other program within the cluster to access the AI guardrails and orchestrator without proper authorization. An attacker could exploit this to gain unauthorized access to sensitive information and potentially make limited changes to the AI models.

A flaw was found in pulp-ansible's bearer-token refresh for collection remotes. The access token is kept in one module-level variable and reused for every token download in that worker. A user who can sync an Ansible remote that uses token refresh, and can point that remote at a server they control, receives an access token obtained for a different remote, and can reuse it at the service that issued it. Content stored in Pulp is not changed, and the service is not stopped.

Busybox: busybox: http request smuggling via pipelined requests in httpd reverse proxy

A flaw was found in BusyBox httpd's reverse proxy feature. When the proxy is configured to forward requests matching a URL prefix to a backend server, only the first HTTP request on a TCP connection has its path rewritten. An attacker can send a pipelined second request that is relayed verbatim to the backend, bypassing the configured path restrictions. This allows accessing arbitrary paths on the backend server that were not intended to be exposed through the proxy.
