sgl-project SGLang
SGLang 0.5.10 through 0.5.22 Code Injection via Debug Dumper Filter
CVSS 4.0
9.2Critical
Official 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.
