Status: DeferredLow (1.9)—

Severity1.9Low · CVSS 4.0

Exploitation probability0.11 %higher than 1% of CVEs

Active exploitationNonot in the CISA catalog

Public exploitNot knownno public code found

A vulnerability was determined in deepseek-ai deepseek-harness up to 0.1.1-rc.2. The impacted element is the function spawn of the component Sandbox. Executing a manipulation of the argument Profile can lead to sandbox issue. It is possible to launch the attack on the local host. The exploit has been publicly disclosed and may be utilized.
