What happened
CISA added CVE-2025-62593 to its Known Exploited Vulnerabilities catalog on 2026-08-17, confirming in-the-wild exploitation of a code injection flaw in Ray, a widely used open-source distributed computing framework heavily used for AI/ML training and serving workloads. The vulnerability combines CWE-94 and CWE-352 and allows remote code execution.
Why it matters
Ray underlies many production ML training/serving pipelines; confirmed active exploitation combined with reports of GPU clusters being hijacked into a cryptomining botnet (ShadowRay 2.0) demonstrates direct compromise of AI training infrastructure at scale.
Attack vector
Code injection reachable via browser (Firefox/Safari) pivoting to Ray's dashboard/API, exploitable even without direct internet exposure of the Ray service by pivoting through a local/trusted network address; leads to remote code execution on the Ray cluster.
Affected systems
Ray-Project Ray (distributed computing/ML framework) versions prior to 2.52.0
Mitigation
Upgrade to Ray >= 2.52.0; CISA federal due date 2026-08-20; Oligo reports unpatched clusters being converted into a self-replicating cryptomining botnet (ShadowRay 2.0) targeting NVIDIA GPU nodes.
