CVE-2026-71102

critical · CVSS 9.1 · Oracle Database Server

Vulnerability in the Portable Clusterware component of Oracle Database Server. Supported versions that are affected are 19.3-19.32, 21.3-21.23 and 23.4.0-23.26.3. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Portable Clusterware. Successful attacks of this vulnerability can result in unauthorized creation, deletion or modification access to critical data or all Portable Clusterware accessible data and unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of Portable Clusterware. CVSS 3.1 Base Score 9.1 (Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:H).

CVE-2026-76850

critical · CVSS 9.8 · LMDeploy

LMDeploy deserializes disaggregated-serving peer messages with pickle. The handle_zmq_recv coroutine in lmdeploy/pytorch/disagg/conn/engine_conn.py reads peer-to-peer cache-free requests with recv_pyobj(), which deserializes the received bytes with pickle.loads(), and the isinstance check against DistServeCacheFreeRequest runs only after deserialization has already completed. The peer that supplies those bytes is caller-controlled: p2p_connect passes remote_engine_endpoint_info.zmq_address from the request body to connect() on the ZMQ PULL socket, and the POST /distserve/p2p_initialize and /distserve/p2p_connect endpoints in lmdeploy/serve/openai/api_server.py apply no authentication unless the server is started with api_keys, which defaults to None. A remote attacker can direct an engine to pull from a ZMQ endpoint under their control and execute arbitrary code in the engine process. Deployments that do not enable disaggregated serving are not affected, because the receive loop is only started once the migration backend accepts the connection.

CVE-2026-17142

critical · CVSS 9.8 · IBM AIX

IBM AIX 7.2, and 7.3 and IBM PowerVM VIOS 4.1 could allow a remote attacker to execute arbitrary commands due to improper authentication.

  • Improper Authentication
  • unix operating system
  • virtualization software

CVE-2026-69836

critical · CVSS 10 · Microsoft Entra ID

Deserialization of untrusted data in Microsoft Entra ID allows an unauthorized attacker to execute code over a network.

  • Remote Code Execution
  • cloud platform
  • authentication service

CVE-2026-61539

critical · CVSS 10 · Xinference

Xinference is an inference API for running open-source, speech, and multimodal models. In 2.5.0 and earlier, Xinference passes attacker-influenced Llama3 tool-call output to eval() in xinference/model/llm/tool_parsers/llama3_tool_parser.py and xinference/model/llm/utils.py. Requests to /v1/chat/completions with a tools field flow through xinference/api/restful_api.py, xinference/model/llm/transformers/core.py, handle_chat_result_non_streaming(), and _post_process_completion() before extract_tool_calls() or _eval_llama3_chat_arguments() evaluates the model-generated Python expression. An unauthenticated remote attacker can influence that output through a crafted prompt and execute commands in the Xinference server process context. This issue is fixed in version 2.7.0.

CVE-2026-63343

critical · CVSS 9.9 · linuxcontainers incus

Incus is a system container and virtual machine manager. Prior to version 7.3.0, a malicious image containing a `metadata.yaml` symlink pointing to an arbitrary host path allows an authenticated Incus user to read or overwrite any file on the host as root via the instance metadata API. The `exec-output` and `templates/` paths were patched in a prior release using `Lstat` rejection and `os.OpenRoot` confinement; `metadata.yaml` was not included in either patch and remains exploitable. Version 7.3.0 patches the issue.

CVE-2026-69502

critical · CVSS 10 · Microsoft Azure SQL Database

Server-side request forgery (ssrf) in Azure SQL Database allows an unauthorized attacker to elevate privileges over a network.

  • Server-Side Request Forgery
  • cloud database

CVE-2026-77651

critical · CVSS 9.8 · Rust Community arrayref

The arrayref crate 0.3.10 for Rust can trigger execution of malicious code when compiling a project that uses the crate, because it has a rogue dependency that registers with a command-and-control server to offer arbitrary code execution.

CVE-2026-77806

critical · CVSS 9.8 · SPIP

SPIP before 4.4.21 allows unauthenticated remote attackers to execute arbitrary code, as exploited in the wild in August 2026. This is related to code injection via an X-Spip-Filtre HTTP request header that is mishandled by analyse_resultat_skel.
