Local request crashes via non-bytes tuple hashing
Published Jun 3, 2026 · Updated Jun 3, 2026
Denial of service in SGLang 0.5.0 through 0.5.11 allows local users to crash multimodal request processing via crafted feature lists. The hash_feature function flattens a non-tensor list into a tuple, which data_hash passes to hashlib.sha256 despite that API requiring bytes-like input. Exploitation requires local low-privileged access and a high-complexity, user-controlled precomputed_embedding feature; the demonstrated consequence is a TypeError in the affected request path.
