CVE-2026-82533 DeepSeek Harness < 0.1.2-alpha.1 Authentication Bypass via Host Header Spoofing

DeepSeek Harness before 0.1.2-alpha.1 contains an authentication bypass vulnerability that grants unauthenticated access to its local HTTP agent-control API by accepting a client-supplied loopback Host header in place of validating the actual TCP connection origin. On the default configuration, a...

CVE-2026-82533

DeepSeek Harness prior to 0.1.2-alpha.1 contains an authentication bypass in its local HTTP control-plane API. The root cause is that the server validates only the client-supplied Host header rather than the actual TCP connection origin, allowing a network attacker to spoof authentication. This p...

Four critical CVEs all stemming from the same fundamental flaw: implicit trust in software components. The OX research team disclosed these vulnerabilities, which share a root cause of insufficient validation of third-party or AI-generated code, leading to sandbox escapes and arbitrary code...

GHSA-86M2-FCXQ-5Q7C 9router: Unauthenticated `/v1` proxy access via `Host`-header spoofing → open AI relay + SSRF

Summary 9router's request guard decides a request is "local" and therefore exempt from API-key auth on the /v1 LLM proxy by reading the client-controlled Host header. Because 9router binds 0.0.0.0 by default and the CLI misleadingly prints "localhost", a remote, unauthenticated attacker who can...
