Check whether you run Amazon AWS, AWS Deadline Cloud worker agent or OpenJD Sessions for Python at an affected version. Junglewise does that check for you around the clock: connect your code, cloud and domains, and it matches new vulnerabilities like this one against what you actually run and tells you when one reaches you.

CVE-2026-126087: OpenJD Sessions for Python untrusted search path in process launcher

CVE-2026-126087 · Severity: high · CVSS 8.8 · Published 2026-11-10

AWS Deadline Cloud worker agent uses OpenJD Sessions for Python to run jobs as unprivileged users on Linux. A flaw in how the library invokes the sudo command allows an authenticated user with job submission permissions to manipulate the PATH environment variable and substitute a malicious sudo binary, gaining code execution as the worker agent OS user and stealing AWS credentials including fleet role and EC2 instance identity credentials.

Technical details

The cross-user process launcher in OpenJD Sessions invokes sudo by bare name in a job-controlled environment, allowing PATH manipulation to point to a attacker-supplied sudo binary. An authenticated remote user with deadline:CreateJob permission can craft a job that modifies PATH and places a malicious sudo executable, achieving arbitrary code execution as the worker agent user. The vulnerability affects Linux only; Windows workers are not affected. It is fixed in OpenJD Sessions 0.11.0 and AWS Deadline Cloud worker agent 0.33.0 by using absolute paths and a fixed list of trusted directories.

Affected products

AWS Deadline Cloud worker agent before 0.33.0
OpenJD Sessions for Python before 0.11.0
