CVE-2026-115749 hydra-ecosystem CVE debrief

Who should care

Defenders responsible for hydra-ray-launcher deployments should assess exposure and apply patches or mitigations to prevent potential module imports. This involves reviewing configuration values and command-line overrides for potential vulnerabilities.

Why it matters

The hydra-ray-launcher package vulnerability allows attackers to import arbitrary modules, potentially leading to import-time side effects, code execution, or data tampering. Defenders should assess exposure and apply patches or mitigations to prevent potential module imports.

• Potential import-time side effects in the application process
• Possible execution of arbitrary code
• Elevation of privileges or access
• Data tampering or exfiltration

Technical summary

The hydra-ray-launcher package, versions 1.1.0.dev1 before 1.2.2 and 1.4.0.dev4 before 1.4.0rc2, is vulnerable to an arbitrary module import issue via the ray_pkg_version OmegaConf resolver. Attackers controlling configuration values or command-line overrides can supply a ray_pkg_version interpolation to import any installed module, triggering its import-time side effects in the application process. This vulnerability allows attackers to potentially execute arbitrary code, elevate privileges, or tamper with data. Defenders should assess exposure and apply patches or mitigations to prevent potential module imports.

Defensive priority

Defenders should prioritize assessing exposure and applying patches or mitigations to prevent potential module imports. This involves reviewing configuration values and command-line overrides for potential vulnerabilities.

Recommended defensive actions

• Assess exposure by reviewing configuration values and command-line overrides for potential vulnerabilities
• Apply patches or mitigations to prevent potential module imports
• Monitor for potential import-time side effects in the application process
• Review compensating controls for exposed systems while remediation is scheduled and verified
• Check relevant monitoring, detection, and logs for exposed assets that need extra review
• Track exceptions, retest remediated assets, and close the item only after evidence is documented
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up

Evidence notes

The vulnerability is confirmed in versions 1.1.0.dev1 and 1.4.0.dev4 of the hydra-ray-launcher package. Patches are available in versions 1.2.2 and 1.4.0rc2. The CVE Program and NVD provide official records of this vulnerability.
