GHSA-Q5HH-P536-9725
Vulnerability from github – Published: 2024-11-14 15:32 – Updated: 2024-11-14 15:32The Migration, Backup, Staging – WPvivid plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 0.9.107 via deserialization of untrusted input in the 'replace_row_data' and 'replace_serialize_data' functions. This makes it possible for unauthenticated attackers to inject a PHP Object. No known POP chain is present in the vulnerable software. If a POP chain is present via an additional plugin or theme installed on the target system, it could allow the attacker to delete arbitrary files, retrieve sensitive data, or execute code. An administrator must create a staging site to trigger the exploit.

Vulnerability from github – Published: 2026-01-09 21:12 – Updated: 2026-01-11 14:55Fickling's assessment
ctypes, importlib, runpy, code and multiprocessing were added the list of unsafe imports (https://github.com/trailofbits/fickling/commit/9a2b3f89bd0598b528d62c10a64c1986fcb09f66, https://github.com/trailofbits/fickling/commit/eb299b453342f1931c787bcb3bc33f3a03a173f9, https://github.com/trailofbits/fickling/commit/29d5545e74b07766892c1f0461b801afccee4f91, https://github.com/trailofbits/fickling/commit/b793563e60a5e039c5837b09d7f4f6b92e6040d1, https://github.com/trailofbits/fickling/commit/b793563e60a5e039c5837b09d7f4f6b92e6040d1).
Original report
Summary
The unsafe_imports() method in Fickling's static analyzer fails to flag several high-risk Python modules that can be used for arbitrary code execution. Malicious pickles importing these modules will not be detected as unsafe, allowing attackers to bypass Fickling's primary static safety checks.
Details
In fickling/fickle.py lines 866-884, the unsafe_imports() method checks imported modules against a hardcoded tuple:
def unsafe_imports(self) -> Iterator[ast.Import | ast.ImportFrom]:
for node in self.properties.imports:
if node.module in (
"__builtin__", "__builtins__", "builtins", "os", "posix", "nt",
"subprocess", "sys", "builtins", "socket", "pty", "marshal", "types",
):
yield node
This list is incomplete. The following dangerous modules are NOT detected:
- ctypes: Allows arbitrary memory access, calling C functions, and bypassing Python restrictions entirely
- importlib: Can dynamically import any module at runtime
- runpy: Can execute Python modules as scripts
- code: Can compile and execute arbitrary Python code
- multiprocessing: Can spawn processes with arbitrary code
Since ctypes is part of the Python standard library, it also bypasses the NonStandardImports analysis.
PoC
from fickling.fickle import Pickled
from fickling.analysis import check_safety, Severity
# Pickle that imports ctypes.pythonapi (allows arbitrary code execution)
# PROTO 4, GLOBAL 'ctypes pythonapi', STOP
payload = b'\x80\x04cctypes\npythonapi\n.'
pickled = Pickled.load(payload)
results = check_safety(pickled)
print(f"Severity: {results.severity.name}")
print(f"Is safe: {results.severity == Severity.LIKELY_SAFE}")
# Output: Severity is LIKELY_SAFE or low - the ctypes import is not flagged
# A truly malicious pickle using ctypes could execute arbitrary code
Impact
Security Bypass (Confidentiality, Integrity, Availability)
An attacker can craft a malicious pickle that:
1. Imports ctypes to gain arbitrary memory access
2. Uses ctypes.pythonapi or ctypes.CDLL to execute arbitrary code
3. Passes Fickling's safety analysis as "likely safe"
4. Executes malicious code when the victim loads the pickle after trusting Fickling's verdict
This undermines the core purpose of Fickling as a pickle safety scanner.

Mitigation
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
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
Explicitly define a final object() to prevent deserialization.
Mitigation
- 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
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
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
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.
