Not enough EPSS history yet.
Unrestricted deserialization of untrusted data in the cursor pagination component in the OpenSearch SQL plugin allows a remote authenticated user with basic read/search permissions to execute arbitrary code on the server by sending a crafted cursor parameter to the plugins/sql endpoint.

CVE-2026-719818.8 HIG—
———Cypht before 2.12.2 contains a PHP object injection vulnerability that allows authenticated attackers to execute arbitrary operating system commands by supplying a crafted PHP object graph in the back_query GET parameter of the logout handler. Attackers can pass a base64-encoded serialized payload through this parameter, which is decoded and passed directly to unserialize() without an allow-list, signature check, or type restriction, enabling gadget-chain exploitation to achieve remote code execution as the web server process.5hCVE-2026-726498.8 HIG—
———Deserialization of Untrusted Data (CWE-502) in the Elasticsearch machine learning component can lead to remote code execution via Object Injection (CAPEC-586). A specially crafted trained model artifact could cause attacker-controlled logic to execute with a materially broader system-call surface than intended. Exploitation requires an authenticated user with sufficient privileges to create and deploy trained models.5hCVE-2026-842028.8 HIG—
———ModelScope uses PyYAML's unsafe yaml.Loader to parse model configuration files, allowing arbitrary code execution through Python object construction tags. Attackers can craft malicious model repositories with poisoned configuration files that execute code when loaded by users.8hCVE-2026-617797.8 HIG—
