CVE-2026-32981: CWE-22 Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') in ray-project Ray
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.
AI Analysis
Technical Summary
A path traversal vulnerability (CWE-22) exists in Ray Dashboard (default port 8265) in Ray versions before 2.8.1. Due to insufficient validation and sanitization of user-supplied path inputs in the static file handler, an attacker can craft traversal sequences (e.g., ../) to access arbitrary files on the local filesystem outside the designated static directory. This vulnerability has a CVSS 4.0 score of 8.7, indicating high severity, and does not require privileges or user interaction to exploit. Multiple Red Hat advisories reference this CVE, indicating vendor awareness and likely patches.
Potential Impact
Successful exploitation allows an unauthenticated attacker to read arbitrary files on the host running Ray Dashboard, potentially exposing sensitive information. This local file disclosure can lead to information leakage and may aid further attacks depending on the disclosed data.
Mitigation Recommendations
A fix is available in Ray version 2.8.1 and later. Users should upgrade to version 2.8.1 or newer to remediate this vulnerability. Refer to the Red Hat advisories for specific patch details and updates. No additional mitigations are indicated by the vendor advisory.
