| CVE-2026-19569 | 1 Zephyrproject | 1 Zephyr | 2026-10-09 | 8.8 High |
| dynamic_object_create() in kernel/userspace/userspace.c computed the backing allocation for a dynamically allocated kernel object as obj_size_get(otype) + size, and for thread stack elements as STACK_ELEMENT_DATA_SIZE(size) (a round-up plus fixed overhead), without checking either expression for unsigned wrap-around. A size close to SIZE_MAX makes the computed total wrap to a very small value, so the heap chunk handed out is a few bytes while the object descriptor is still tagged with the full requested type and registered in the kernel object table. The size argument reaches that arithmetic directly from user mode. k_object_alloc_size() is declared __syscall in include/zephyr/sys/kobject.h, its verifier z_vrfy_k_object_alloc_size() in kernel/userspace/userspace_handler.c is a bare pass-through, and z_object_alloc() only range-checks otype — nothing bounds size. The stack-element branch is additionally reachable through the k_thread_stack_alloc() syscall via kernel/dynamic.c. Because subsequent kernel-object validation checks only the object's type and initialization state, the undersized handle passes K_SYSCALL_OBJ_INIT()/K_SYSCALL_OBJ_NEVER_INIT(), and the matching init syscall (for example k_mutex_init(), k_sem_init(), or k_thread_create()) then writes a complete object over the truncated allocation. An unprivileged user-mode thread can therefore trigger a supervisor-mode out-of-bounds write into the kernel resource-pool heap, of a size and content it substantially controls, corrupting sys_heap chunk metadata and adjacent kernel objects. Under CONFIG_GEN_PRIV_STACKS the thread-stack branch additionally stores an attacker-influenced wild pointer as a user thread's privileged stack base. The practical result is escape from the CONFIG_USERSPACE sandbox — kernel-level code execution or at minimum kernel memory corruption and system compromise. Exploitation requires CONFIG_USERSPACE together with CONFIG_DYNAMIC_OBJECTS (also selected by CONFIG_DYNAMIC_THREAD under userspace), and a calling thread with an assigned resource pool. The fix rejects both overflowing computations and frees the partially built descriptor. | ||||
| CVE-2026-108157 | 1 Smp46 | 1 Pingvin-share-x | 2026-10-09 | 8.1 High |
| Pingvin Share X from 0.19.0 before 1.22.0 contains an improper authentication vulnerability that allows remote unauthenticated attackers to take over accounts by abusing automatic OAuth email linking in OAuthService.signUp(). Attackers can register a victim's unverified email on an enabled OAuth/OIDC provider, exploiting the missing email_verified check in GenericOidcProvider, to sign in as the victim including administrators while bypassing TOTP. | ||||
| CVE-2026-106155 | 1 Progress Software | 1 Telerik Report Server | 2026-10-09 | 8.9 High |
| In Progress® Telerik® Report Server prior to version 12.2.26.1007, a stored cross-site scripting vulnerability in the shared reporting engine allows an authenticated report author to embed javascript: or vbscript: URLs in report navigation actions or HTML text box links. When another user views the malicious report and the embedded navigation is triggered, attacker-controlled script can execute in the web report viewer's origin. In a multi-user Report Server deployment, this can enable privilege escalation by performing actions in a higher-privilege user's authenticated session, including an administrator's session. | ||||
| CVE-2026-106145 | 1 Progress | 1 Telerik Report Server | 2026-10-09 | 7.1 High |
| In Progress® Telerik® Report Server prior to version 12.2.26.1007, incorrect privilege assignment in the service-agent SignalR hub allows an authenticated user, including a low-privilege or guest account with a valid bearer token, to register as a trusted service agent. On the next server settings-synchronization event, the rogue agent receives storage settings and encryption private keys. This privilege escalation enables disclosure of protected secrets, including stored data-source credentials and connection strings, and allows agent impersonation and interference with task dispatch. | ||||
| CVE-2026-102554 | 1 Google | 1 Guava | 2026-10-09 | 7.5 High |
| Allocation of resources without limits or throttling (CWE-770) during Java object deserialization in Google Guava versions 4.0 through 33.7.1 allows an attacker to cause a Denial of Service via OutOfMemoryError. When deserializing CompactHashMap, CompactHashSet, or MapMakerInternalMap instances, Guava eagerly allocates an array based on a caller-specified size parameter without throttling, permitting memory exhaustion from crafted serialization streams. | ||||
| CVE-2026-78659 | 1 Go Standard Library | 2 Net/http, Net/http2 | 2026-10-09 | 7.5 High |
| When "Trailer" headers are sent by a client, the HTTP server internally uses the header values to populate the Request.Trailer map passed to the server handler. Because Request.Trailer is a map, each entry incurs memory overhead. For HTTP/2 servers, a malicious client can exploit this by sending a "Trailer" header that declares a large number of fields, causing the server to allocate a disproportionate amount of memory while bypassing Server.MaxHeaderValueCount and Server.MaxHeaderBytes limits. This exploit is not applicable for HTTP/1 servers, which do not support multiplexing a large number of requests over one TCP connection, and whose Server.MaxHeaderBytes are calculated differently. | ||||
| CVE-2026-106505 | 2 Backstage, Linuxfoundation | 4 Backstage, Plugin-techdocs-node, Backstage and 1 more | 2026-10-09 | 7.7 High |
| Backstage is an open framework for building developer portals. Prior to 1.14.6 and 1.15.4, the @backstage/plugin-techdocs-node package is affected by bypass of mkdocs configuration sanitizer in techdocs backend. Users with the ability to commit changes to a repository that uses TechDocs can circumvent the MkDocs configuration file sanitizer introduced in response to CVE-2026-25153 and execute arbitrary code on the TechDocs backend host during documentation generation. This issue is fixed in versions 1.14.6 and 1.15.4. | ||||
| CVE-2026-106509 | 2 Backstage, Linuxfoundation | 4 Backstage, Plugin-techdocs-node, Backstage and 1 more | 2026-10-09 | 7.7 High |
| Backstage is an open framework for building developer portals. Prior to 1.14.6, the @backstage/plugin-techdocs-node package is affected by improper validation of mkdocs theme configuration in techdocs. When TechDocs is configured to build documentation locally or in a container, a user with write access to a registered repository can include configuration values in mkdocs.yml that cause arbitrary code execution during the documentation build process. This issue is fixed in versions 1.14.6 and 1.15.4. | ||||
| CVE-2026-94439 | 1 Go Standard Library | 1 Net/http | 2026-10-09 | 7.5 High |
| When an HTTP server handler sends a 2xx response to an HTTP/1 CONNECT request and returns without hijacking the connection, the server improperly continues to read and serve requests from the connection. Since a 2xx response to an HTTP/1 CONNECT converts the connection into a tunnel, the server should not treat the connection as continuing to contain HTTP. The impact of this misbehavior is mostly limited to potential request smuggling, where an intermediate proxy considers the data on the connection to be tunneled and the server considers it to be HTTP. | ||||
| CVE-2026-7827 | 1 Falkordb | 1 Falkordb | 2026-10-09 | 8.1 High |
| A stack-based buffer overflow in the _RdbLoadEntity function of the RDB graph decoders (src/serializers/decoders/*/decode_graph_entities.c) in FalkorDB before 4.18.4 allows a remote attacker who can issue Redis replication commands (for example, against an instance with no password configured) to cause a denial of service and possibly execute arbitrary code by supplying a crafted RDB stream with an attacker-controlled entity property count. The count sizes two variable-length arrays on the thread stack with no upper bound, and the decoder then fills them with attacker-supplied values. | ||||
| CVE-2026-78669 | 1 Go Standard Library | 2 Net/http, Net/http2 | 2026-10-09 | 7.5 High |
| A malicious HTTP/2 peer can cause excessive CPU consumption in the client or server by opening a large number of streams and then sending many small SETTINGS frames containing SETTINGS_INITIAL_WINDOW_SIZE values. | ||||
| CVE-2026-78667 | 1 Go Standard Library | 1 Net/http | 2026-10-09 | 7.5 High |
| When parsing a Range header containing a large number of small ranges, FileServer(FS), ServeContent, and ServeFile(FS) can consume an excessive amount of CPU. | ||||
| CVE-2026-107911 | 1 Falkordb | 1 Falkordb | 2026-10-09 | 7.5 High |
| A type confusion vulnerability in the _read_flags function (src/commands/cmd_dispatcher.c) in FalkorDB before 4.20.0 allows a remote authenticated attacker who can run GRAPH.QUERY to cause a denial of service and possibly disclose or corrupt memory. The function accepts a --bolt argument from any client and casts the following command argument, a Redis string object, to a Bolt client structure without checking its origin; the result-set code then dereferences pointers read from that object. The argument is parsed even when the Bolt endpoint is disabled, so default configurations are affected. | ||||
| CVE-2026-93548 | 2026-10-09 | 8.8 High | ||
| The FooSales WordPress plugin before 1.43.3 does not verify that an authenticated caller is entitled to act as the user a request names, allowing any authenticated user to have the FooSales WordPress plugin before 1.43.3 act as an arbitrary other user, including an administrator, resulting in that user's account details being exposed and their account being taken over. | ||||
| CVE-2026-82344 | 1 Ibm | 1 Guardium Data Protection | 2026-10-09 | 8.1 High |
| IBM Guardium Data Protection 12.0, 12.1 is vulnerable to a heap-based buffer overflow in the S-TAP TrafficTap TDS login reassembly functionality. An unauthenticated remote attacker can send crafted TDS login fragments that exceed the fixed-size reassembly buffer, potentially resulting in denial of service or arbitrary code execution on the affected system. | ||||
| CVE-2026-46569 | 1 Tuxera | 1 Ntfs-3g | 2026-10-09 | 7.7 High |
| In NTFS-3G before 2026.7.7, a heap buffer overflow exists in ntfs_ib_copy_tail(), in libntfs-3g/index.c, that allows an attacker to corrupt heap memory in the SUID-root ntfs-3g binary by crafting a malicious NTFS image. The overflow is triggered by extending a directory, e.g., by creating a file. | ||||
| CVE-2024-4540 | 1 Redhat | 3 Build Keycloak, Red Hat Single Sign On, Rhosemc | 2026-10-09 | 7.5 High |
| A flaw was found in Keycloak in OAuth 2.0 Pushed Authorization Requests (PAR). Client-provided parameters were found to be included in plain text in the KC_RESTART cookie returned by the authorization server's HTTP response to a `request_uri` authorization request, possibly leading to an information disclosure vulnerability. | ||||
| CVE-2026-106334 | 1 Google | 1 Chrome | 2026-10-09 | 8.8 High |
| Information leak in Payments in Google Chrome prior to 155.0.8059.39 allowed a remote attacker leveraging social engineering to obtain sensitive information via a crafted HTML page. (Chromium security severity: Low) | ||||
| CVE-2026-103958 | 1 Aws | 1 Loom | 2026-10-09 | 7.6 High |
| Server-side request forgery in the tool server and remote agent connection handling in Loom for AWS before 1.7.0 might allow an authenticated remote user to obtain the credentials of the application's own container role and to read responses from arbitrary internal network locations, via a crafted connection address supplied when registering, updating or testing a tool server or remote agent. To remediate this issue, users should upgrade to version 1.7.0 or later. | ||||
