Summary
VCR.py: Arbitrary code execution via unsafe YAML deserialization of cassette files
Details

Summary

vcrpy deserializes YAML cassette files with PyYAML's object-constructing loader (yaml.CLoader / yaml.Loader) instead of the safe loader (yaml.CSafeLoader / yaml.SafeLoader). A cassette containing a !!python/object/apply: (or similar) tag therefore executes arbitrary Python code the moment the cassette is loaded — including through the normal VCR().use_cassette() path, before any HTTP interaction is replayed.

This is not limited to environments lacking the libYAML C extension. CLoader uses the C parser but PyYAML's full Python constructor, so Python object tags execute under CLoader exactly as under the pure-Python Loader. Confirmed against vcrpy 8.1.1 + PyYAML 6.0.3 with CLoader active.

Affected component

  • vcr/serializers/yamlserializer.py — deserialize() → yaml.load(cassette_string, Loader=Loader) where Loader is CLoader/Loader. Reached on every cassette load.
  • vcr/migration.py (~line 107) — yaml.load(preprocess_yaml(...), Loader=Loader). A second sink reached when the migration tool is run on a .yaml file. preprocess_yaml() only strips three known legacy tags, so other tags still execute.

Present in all releases inspected, 1.0.0 through 8.1.1.

Proof of concept

import vcr, requests

# Attacker-supplied cassette. The payload sits in an ignored top-level key
# so the rest of the cassette stays valid; it fires during load.
open("evil.yaml", "w").write("""interactions:
- request:
    body: null
    headers: {Accept: ['*/*']}
    method: GET
    uri: http://example.com/
  response:
    body: {string: ok}
    headers: {Content-Type: ['text/plain']}
    status: {code: 200, message: OK}
_x: !!python/object/apply:os.system ['touch /tmp/VCRPY_YAML_RCE']
version: 1
""")

with vcr.use_cassette("evil.yaml"):      # <-- /tmp/VCRPY_YAML_RCE created here
    requests.get("http://example.com/")

Loading the cassette creates /tmp/VCRPY_YAML_RCE, demonstrating arbitrary command execution. Any Python callable can be invoked this way.

Impact

Arbitrary code execution in the process that loads the cassette, with that process's full privileges. Realistic delivery paths:

  • A malicious cassette added in a pull request and loaded when CI runs the tests.
  • A poisoned shared test-fixture repository or cassette artifact store.
  • "Updated recorded HTTP fixtures" social-engineering.

Because cassettes are typically loaded by test suites in CI/CD and on developer machines, the exposed secrets are exactly the high-value ones in those environments: CI deployment credentials, cloud IAM roles, registry/publishing tokens, and source access.

Patch

Use the safe loader in vcr/serializers/yamlserializer.py:

try:
    from yaml import CDumper as Dumper
    from yaml import CSafeLoader as Loader
except ImportError:
    from yaml import Dumper
    from yaml import SafeLoader as Loader

def deserialize(cassette_string):
    return yaml.load(cassette_string, Loader=Loader)

Apply the same SafeLoader change in vcr/migration.py.

This is backwards compatible: vcrpy cassettes only contain standard YAML (scalars/lists/maps plus !!binary, all supported by SafeLoader/CSafeLoader), so existing cassettes load unchanged. vcrpy's serialize.deserialize() already catches yaml.constructor.ConstructorError, so a Python-tagged cassette now surfaces as the existing "old cassette format" ValueError instead of executing.

Recommended hardening: add a regression test that loads a cassette containing !!python/object/apply:os.system and asserts a ConstructorError/ValueError and that no side effect occurs.

Summary
PyYAML insecurely deserializes YAML strings leading to arbitrary code execution
Details

In PyYAML before 5.1, the yaml.load() API could execute arbitrary code. In other words, yaml.safe_load is not used.

This was intended to be fixed in 4.1, but due to breaking changes, 4.1 was yanked and 5.1 contains the patch for CVE-2017-18342.

Summary
Deserialization of Untrusted Data in Apache Hadoop YARN
Details

ZKConfigurationStore which is optionally used by CapacityScheduler of Apache Hadoop YARN deserializes data obtained from ZooKeeper without validation. An attacker having access to ZooKeeper can run arbitrary commands as YARN user by exploiting this. Users should upgrade to Apache Hadoop 2.10.2, 3.2.4, 3.3.4 or later (containing YARN-11126) if ZKConfigurationStore is used.

Mitigation
Architecture and Design Implementation

If available, use the signing/sealing features of the programming language to assure that deserialized data has not been tainted. For example, a hash-based message authentication code (HMAC) could be used to ensure that data has not been modified.

Mitigation
Implementation

When deserializing data, populate a new object rather than just deserializing. The result is that the data flows through safe input validation and that the functions are safe.

Mitigation
Implementation

Explicitly define a final object() to prevent deserialization.

Mitigation
Architecture and Design Implementation
  • Make fields transient to protect them from deserialization.
  • An attempt to serialize and then deserialize a class containing transient fields will result in NULLs where the transient data should be. This is an excellent way to prevent time, environment-based, or sensitive variables from being carried over and used improperly.
Mitigation
Implementation

Avoid having unnecessary types or gadgets (a sequence of instances and method invocations that can self-execute during the deserialization process, often found in libraries) available that can be leveraged for malicious ends. This limits the potential for unintended or unauthorized types and gadgets to be leveraged by the attacker. Add only acceptable classes to an allowlist. Note: new gadgets are constantly being discovered, so this alone is not a sufficient mitigation.

Mitigation
Architecture and Design Implementation

Employ cryptography of the data or code for protection. However, it's important to note that it would still be client-side security. This is risky because if the client is compromised then the security implemented on the client (the cryptography) can be bypassed.

Mitigation MIT-29
Operation

Strategy: Firewall

Use an application firewall that can detect attacks against this weakness. It can be beneficial in cases in which the code cannot be fixed (because it is controlled by a third party), as an emergency prevention measure while more comprehensive software assurance measures are applied, or to provide defense in depth [REF-1481].

CAPEC-586: Object Injection

An adversary attempts to exploit an application by injecting additional, malicious content during its processing of serialized objects. Developers leverage serialization in order to convert data or state into a static, binary format for saving to disk or transferring over a network. These objects are then deserialized when needed to recover the data/state. By injecting a malformed object into a vulnerable application, an adversary can potentially compromise the application by manipulating the deserialization process. This can result in a number of unwanted outcomes, including remote code execution.
