|---|---|---|---|---|---|---|
CVE-2026-41486HIGH | Ray: Remote Code Execution via Parquet Arrow Extension Type DeserializationRay is an AI compute engine. From version 2.54.0 to before version 2.55.0, Ray Data registers custom Arrow extension types (ray.data.arrow_tensor, ray.data.arrow_tensor_v2, ray.data.arrow_variable_shaped_tensor) globally in PyArrow. When PyArrow reads a Parquet file containing one of these extension types, it calls __arrow_ext_deserialize__ on the field's metadata bytes. Ray's implementation passes these bytes directly to cloudpickle.loads(), achieving arbitrary code execution during schema pars… | CVSS8.9v4.0 | EPSS0.473% | PoCs0 | SignalsNot listed in CISA KEVNo known ransomware useNo Nuclei templates | STIX |
CVE-2026-32981HIGH | Ray Dashboard <= 2.8.0 Path Traversal Leading to Local File DisclosureA path traversal vulnerability was identified in Ray Dashboard (default port 8265) in Ray versions prior to 2.8.1. Due to improper validation and sanitization of user-supplied paths in the static file handling mechanism, an attacker can use traversal sequences (e.g., ../) to access files outside the intended static directory, resulting in local file disclosure.

CVE-2026-27482MEDIUM | Ray: Dashboard DELETE endpoints allow unauthenticated browser-triggered DoS (Serve shutdown / job deletion)Ray is an AI compute engine. In versions 2.53.0 and below, thedashboard HTTP server blocks browser-origin POST/PUT but does not cover DELETE, and key DELETE endpoints are unauthenticated by default. If the dashboard/agent is reachable (e.g., --dashboard-host=0.0.0.0), a web page via DNS rebinding or same-network access can issue DELETE requests that shut down Serve or delete jobs without user interaction. This is a drive-by availability impact. The fix for this vulnerability is to update to Ray … | CVSS5.9v3.1 | EPSS0.256% | PoCs0 | SignalsNot listed in CISA KEVNo known ransomware useNo Nuclei templates | STIX |
CVE-2025-62593CRITICAL | Ray is vulnerable to RCE via Safari & Firefox Browsers through DNS Rebinding AttackRay is an AI compute engine. Prior to version 2.52.0, developers working with Ray as a development tool can be exploited via a critical RCE vulnerability exploitable via Firefox and Safari. This vulnerability is due to an insufficient guard against browser-based attacks, as the current defense uses the User-Agent header starting with the string "Mozilla" as a defense mechanism. This defense is insufficient as the fetch specification allows the User-Agent header to be modified. Combined with a DN… | CVSS9.4v4.0 | EPSS0.369% | PoCs0 | SignalsNot listed in CISA KEVNo known ransomware useNo Nuclei templates | STIX |
CVE-2023-6020HIGH | Ray Static File Local File IncludeLFI in Ray's /static/ directory allows attackers to read any file on the server without authentication. | CVSS7.5v3.1 | EPSS14.5% | PoCs1 | SignalsNot listed in CISA KEVNo known ransomware use1 Nuclei template | STIX |
CVE-2023-6019CRITICAL | Ray Command Injection in cpu_profile ParameterA command injection existed in Ray's cpu_profile URL parameter allowing attackers to execute os commands on the system running the ray dashboard remotely without authentication. The issue is fixed in version 2.8.1+.
