Summary
Auth0 Symfony SDK Deserialization of Untrusted Data vulnerability
Details

Overview The Auth0 Symfony SDK contains a critical vulnerability due to insecure deserialization of cookie data. If exploited, since SDKs process cookie content without prior authentication, a threat actor could send a specially crafted cookie containing malicious serialized data.

Am I Affected? You are affected by this vulnerability if you meet the following preconditions:

  1. Applications using the Auth0 Symfony SDK, versions between 5.0.0 BETA-0 to 5.0.0.
  2. Auth0 Symfony SDK uses the Auth0-PHP SDK with version 8.0.0-BETA3 to 8.3.0.

Fix Upgrade Auth0/symfony to the latest version (v5.4.0).

Acknowledgement Okta would like to thank Andreas Forsblom for discovering this vulnerability.

Vulnerability from github – Published: 2026-03-26 06:30 – Updated: 2026-03-26 06:30
VLAI
Details

The Frontend Admin by DynamiApps plugin for WordPress is vulnerable to PHP Object Injection via deserialization of the 'post_content' of admin_form posts in all versions up to, and including, 3.28.31. This is due to the use of WordPress's maybe_unserialize() function without class restrictions on user-controllable content stored in admin_form post content. This makes it possible for authenticated attackers, with Editor-level access and above, to inject a PHP Object. The additional presence of a POP chain allows attackers to achieve remote code execution.

Summary
Apache MINA vulnerable to Deserialization of Untrusted Data (CVE-2026-41409 Incomplete Fix)
Details

The fix for CVE-2026-41409 was not applied to the 2.1.X and 2.2.X branches. Here was the original issue description:

The fix for CVE-2024-52046 in Apache MINA AbstractIoBuffer.getObject() was incomplete. The classname allowlist of classes allowed to be deserialized was applied too late after a static initializer in a class to be read might already have been executed.

Affected versions are Apache MINA 2.1.0 <= 2.1.11, and 2.2.0 <= 2.2.6.

The problem is resolved in Apache MINA 2.1.12, and 2.2.7 by applying the classname allowlist earlier.

Affected are applications using Apache MINA that call IoBuffer.getObject().

Applications using Apache MINA are advised to upgrade.

Summary
APScheduler's JSONSerializer and CBORSerializer are vulnerable to Remote Code Execution (RCE) via Insecure Deserialization
Details

The JSONSerializer and CBORSerializer in APScheduler (all versions including 3.10.x and 4.0.0a5) are vulnerable to Remote Code Execution (RCE) via Insecure Deserialization. The unmarshal_object function allows for arbitrary class instantiation and state injection by dynamically importing modules and calling setstate on any class available in the Python environment. An attacker can exploit this by submitting a specially crafted JSON or CBOR payload to an application using these serializers

Vulnerability from github – Published: 2023-04-06 21:30 – Updated: 2024-03-21 03:35
VLAI
Details

** UNSUPPORTED WHEN ASSIGNED ** A Java insecure deserialization vulnerability in Adobe LiveCycle ES4 version 11.0 and earlier allows unauthenticated remote attackers to gain operating system code execution by submitting specially crafted Java serialized objects to a specific URL. Adobe LiveCycle ES4 version 11.0.1 and later may be vulnerable if the application is installed with Java environment 7u21 and earlier. Exploitation of the vulnerability depends on two factors: insecure deserialization methods used in the Adobe LiveCycle application, and the use of Java environments 7u21 and earlier. The code execution is performed in the context of the account that is running the Adobe LiveCycle application. If the account is privileged, exploitation provides privileged access to the operating system. NOTE: This vulnerability only affects products that are no longer supported by the maintainer.

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.
