CVE-2026-93034
9.8 CRITICALpublic exploit availablePublished 2026-10-08 · Updated 2026-10-08
AI risk analysis
- Summary
- The flaw in SGLang allows arbitrary code execution due to untrusted PickleWrapper payloads being deserialized without proper validation or authentication, making it a critical vulnerability.
- Exploitability
- Exploitation is relatively straightforward if data-parallel attention is enabled and a non-loopback --dist-init-addr setting is used, requiring minimal attacker interaction.
- Blast radius
- If exploited, this vulnerability could lead to complete system compromise, allowing attackers to execute arbitrary code on the affected system.
- Detection
- No reliable host or network indicator is derivable from the published description.
- Prioritized remediation
- Disable data-parallel attention or ensure that --dist-init-addr is set to a loopback address to mitigate the risk.

NVD description
SGLang contains an arbitrary code execution vulnerability caused by the ZMQ message decoder unconditionally deserializing PickleWrapper payloads via pickle.loads() in _maybe_unwrap_pickle without type allowlisting or authentication; this vulnerability persists via the msgpack path even when SGLANG_USE_PICKLE_IPC is disabled, and becomes remotely exploitable if data-parallel attention is enabled with a non-loopback --dist-init-addr setting.
