SGLang contains an RCE vulnerability when the optional dumper subsystem is enabled, allowing for a sandbox escape when DUMPER_SERVER_PORT is set,… (CVE-2026-15971)
SGLang has a remote code execution (RCE) vulnerability that occurs when the optional dumper subsystem is enabled and the DUMPER_SERVER_PORT is set. This vulnerability allows an attacker to escape the sandbox and execute arbitrary code during inference requests. No specific affected versions or patches are currently identified. There is no evidence of known exploits in the wild at this time.
AI Analysis
Technical Summary
The SGLang software contains a remote code execution vulnerability triggered when the optional dumper subsystem is enabled and the environment variable DUMPER_SERVER_PORT is configured. This configuration enables an attacker to escape the sandbox environment and execute arbitrary code on the system during inference requests. The vulnerability is identified as CVE-2026-15971. No CVSS score or detailed technical exploit information is provided. No affected versions or patch information is available from the current data.
Potential Impact
Successful exploitation of this vulnerability allows an attacker to escape the sandbox and execute arbitrary code on the affected system during inference requests, potentially leading to full system compromise. However, there is no indication of active exploitation in the wild.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, avoid enabling the optional dumper subsystem or setting DUMPER_SERVER_PORT if possible, to reduce exposure.
