CVE-2026-111391
SGLang 0.5.10 through 0.5.22 Code Injection via Debug Dumper Filter
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.

Solution
- Update SGLang to a version later than 0.5.22.
- Ensure DUMPER_SERVER_PORT is not exposed.
- Validate filter expressions for safety.
- Restrict access to the /dumper/configure endpoint.
