Bifrost
Monthly
Unauthenticated remote code execution in Maxim AI's Bifrost LLM gateway (transports v2.0.0 and earlier) allows any network caller to run arbitrary programs as the gateway process user. Bifrost's management API registers MCP stdio clients as a raw command-plus-args pair and launches that program immediately upon registration with no MCP handshake, and because governance.auth_config.is_enabled defaults to false, a single POST /api/mcp/client requires no credentials. A vendor patch exists (transports/v2.1.0), which refuses unauthenticated stdio registration with HTTP 403; no public exploit is identified at time of analysis, though the attack is trivially scriptable.
Improper authorization in Bifrost's vtoken-minting and slpx Substrate pallets lets any signed on-chain account attribute its mint volume to an arbitrary registered channel_id it does not control. Because the mint path never verifies that the caller is authorized to mint on behalf of the supplied channel, an attacker can inflate a target (or attacker-owned) channel's recorded mint volume and skew protocol commission settlement so payouts are disproportionately routed to that channel. There is no public exploit identified at time of analysis and EPSS is very low (0.14%), but the flaw directly enables financial value redirection within a live DeFi parachain.
Bifrost HTTP transport before version 2.0.0 exposes an unauthenticated plugin installation endpoint (POST /api/plugins) that accepts HTTP URLs as plugin paths, enabling SSRF on all build types and unauthenticated remote code execution on dynamically linked builds. Because management authentication is disabled by default (governance.auth_config.is_enabled=false), no credentials are required to trigger the flaw; the shared-object loader fetches the attacker-supplied URL, writes it as a temporary .so, and on DYNAMIC=1 builds calls plugin.Open() which immediately executes the plugin's Init() function as the Bifrost process user. Reported by JFrog, the fix ships in transports/v2.0.0, adding an SSRF-safe dial context (SSRFSafeDialContextWithAllowlist) around plugin downloads; no public exploit code or active exploitation has been confirmed at time of analysis.
Bifrost is a heterogeneous middleware that synchronizes MySQL, MariaDB to Redis, MongoDB, ClickHouse, MySQL and other services for production environments. Rated high severity (CVSS 8.8), this vulnerability is remotely exploitable, low attack complexity. This Improper Authentication vulnerability could allow attackers to bypass authentication mechanisms to gain unauthorized access.
Bifrost is a middleware package which can synchronize MySQL/MariaDB binlog data to other types of databases. Rated medium severity (CVSS 6.5), this vulnerability is remotely exploitable, low attack complexity. Public exploit code available and no vendor patch available.
