Details

The Ocean Extra WordPress plugin before 2.0.5 unserialises the content of an imported file, which could lead to PHP object injections issues when a high privilege user import (intentionally or not) a malicious Customizer Styling file and a suitable gadget chain is present on the blog.

Summary
RCE vulnerability in Jenkins Yaml Axis Plugin
Details

Yaml Axis Plugin 0.2.0 and earlier does not configure its YAML parser to prevent the instantiation of arbitrary types. This results in a remote code execution (RCE) vulnerability exploitable by users able to configure a multi-configuration (Matrix) job, or control the contents of a previously configured job’s SCM repository.

Yaml Axis Plugin 0.2.1 configures its YAML parser to only instantiate safe types.

Vulnerability from github – Published: 2026-04-08 19:17 – Updated: 2026-04-09 14:29
VLAI
Summary
PraisonAI Vulnerable to Remote Code Execution via YAML Deserialization in Agent Definition Loading
Details

Summary

The AgentService.loadAgentFromFile method uses the js-yaml library to parse YAML files without disabling dangerous tags (such as !!js/function and !!js/undefined). This allows an attacker to craft a malicious YAML file that, when parsed, executes arbitrary JavaScript code. An attacker can exploit this vulnerability by uploading a malicious agent definition file via the API endpoint, leading to remote code execution (RCE) on the server.

Details

The vulnerability exists in the YAML deserialization process. The js-yaml library's load function is used without specifying a safe schema (e.g., JSON_SCHEMA or DEFAULT_SAFE_SCHEMA). This enables the parsing of JavaScript functions and other dangerous types. When a malicious YAML file containing a !!js/function tag is parsed, the function is evaluated, leading to arbitrary code execution.

The vulnerable code is located in src/agents/agent.service.ts at line 55.

PoC

An attacker can create a malicious agent YAML file with the following content:

!!js/function >
  function(){ require('child_process').execSync('touch /tmp/pwned') }

Then, upload this file as an agent definition via the API endpoint that uses AgentService.loadAgentFromFile. When the agent is loaded (either during startup or via an API call that triggers loading), the payload will execute the command touch /tmp/pwned, demonstrating arbitrary code execution.

Impact

This vulnerability allows an unauthenticated attacker (if the API endpoint is unprotected) or an authenticated attacker with the ability to upload agent definitions to execute arbitrary code on the server. This can lead to complete compromise of the server, data theft, or further network penetration.

Recommended Fix

Replace the unsafe load method with a safe alternative. Specifically, use the load method with a safe schema, such as JSON_SCHEMA or DEFAULT_SAFE_SCHEMA. For example:

import yaml from 'js-yaml';
import { JSON_SCHEMA } from 'js-yaml';

// In the loadAgentFromFile method
const agent = yaml.load(fileContent, { schema: JSON_SCHEMA });

Alternatively, if the application requires only a subset of YAML features, consider using the safeLoad method from an older version (though note it was deprecated). The key is to avoid loading tags that can execute code.

Additionally, validate and sanitize all user input, especially file uploads. Ensure that agent definition files are only uploaded by trusted users and consider storing them in a secure location with proper access controls.

Vulnerability from github – Published: 2022-05-14 02:00 – Updated: 2022-05-14 02:00
VLAI
Details

HandleRequestAsync in Docker for Windows before 18.06.0-ce-rc3-win68 (edge) and before 18.06.0-ce-win72 (stable) deserialized requests over the \.\pipe\dockerBackend named pipe without verifying the validity of the deserialized .NET objects. This would allow a malicious user in the "docker-users" group (who may not otherwise have administrator access) to escalate to administrator privileges.

GHSA-3334-F37Q-2M8X

Vulnerability from github – Published: 2022-05-24 16:45 – Updated: 2024-04-04 00:38
VLAI
Details

A vulnerability has been identified in LOGO! Soft Comfort (All versions). The vulnerability could allow an attacker to execute arbitrary code if the attacker tricks a legitimate user to open a manipulated project. In order to exploit the vulnerability, a valid user must open a manipulated project file. No further privileges are required on the target system. The vulnerability could compromise the confidentiality, integrity and availability of the engineering station. At the time of advisory publication no public exploitation of this security vulnerability was known.

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.
