Ecosystem-wide dependent count for version 2.8.1.
DescriptionCVE.org
A 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.
AnalysisAI
Unauthenticated attackers can read arbitrary files on systems running Ray versions before 2.8.1 by exploiting a path traversal flaw in the Dashboard's static file handler on port 8265. The vulnerability stems from insufficient input validation that allows directory traversal sequences to bypass access controls, and public exploit code is available. …

Vulnerability AssessmentAI
| Exploitation | Remote unauthenticated attacker accessing Ray Dashboard (default port 8265) on Ray versions prior to 2.8.1. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This vulnerability presents a significant real-world risk based on multiple threat intelligence signals. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker identifies a Ray Dashboard instance exposed to the internet on port 8265 through scanning or search engines like Shodan. Using the publicly available exploit code, they craft HTTP requests containing path traversal sequences (e.g., GET /static/../../../../etc/passwd) to read sensitive files such as configuration files, SSH keys, or application secrets. … |
| Remediation | Upgrade Ray to version 2.8.1 or later immediately to address this vulnerability, as this version includes the necessary input validation fixes for the Dashboard's static file handler. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: Inventory all Ray deployments and identify systems running versions prior to 2.8.1; restrict network access to port 8265 (Ray Dashboard) to trusted administrators only. …
