SGLang 0.5.10 through 0.5.22 Code Injection via Debug Dumper Filter

Published Oct 16, 2026 CVSS 4.0 · 9.2 Critical EPSS < 1% KEV · Not listed
Description
SGLang 0.5.10 through 0.5.22 contains a code injection vulnerability in _evaluate_filter() that allows remote attackers to execute Python code by escaping the eval() sandbox through re.search __globals__. Attackers can send a crafted filter expression to the unauthenticated /dumper/configure endpoint when DUMPER_SERVER_PORT is set, running code in the scheduler process on the next forward pass.
