CVE-2026-126087

Untrusted search path in the cross-user process launcher in OpenJD Sessions for Python, as used in the AWS Deadline Cloud worker agent

Published Nov 10, 2026 CVSS 4.0 · 9.4 Critical EPSS < 1% KEV · Not listed
Description
Untrusted search path in the cross-user process launcher in Open Job Description (OpenJD) Sessions for Python before 0.11.0, as used in the AWS Deadline Cloud worker agent before 0.33.0, on Linux might allow an authenticated remote user with permission to submit jobs to a queue to execute arbitrary code as the worker agent OS user and obtain the AWS credentials held by the worker agent via a crafted job that modifies the PATH environment variable.



To remediate this issue, users of customer-managed fleets should upgrade the Deadline Cloud worker agent to version 0.33.0 or later, which includes OpenJD Sessions 0.11.0. Service-managed fleets were remediated service-side.
