Vulnerability from github – Published: 2026-03-04 03:31 – Updated: 2026-03-04 21:32Concrete CMS below version 9.4.8 is vulnerable to Remote Code Execution by stored PHP object injection into the Express Entry List block via the columns parameter. An authenticated administrator can store attacker-controlled serialized data in block configuration fields that are later passed to unserialize() without class restrictions or integrity checks.

GHSA-GM2P-WF5C-W3PJ
Vulnerability from github – Published: 2025-04-21 16:19 – Updated: 2025-10-14 21:59Summary
Amazon.IonDotnet (ion-dotnet) is a .NET library with an implementation of the Ion data serialization format.
An issue exists in Amazon.IonDotnet and the RawBinaryReader class where, under certain conditions, an actor could trigger an infinite loop condition.
Impact
When reading binary Ion data through Amazon.IonDotnet using the RawBinaryReader class, Amazon.IonDotnet does not check the number of bytes read from the underlying stream while deserializing the binary format. If the Ion data is malformed or truncated, this triggers an infinite loop condition that could potentially result in a denial of service.
Impacted versions: <=1.3.0
Patches
This issue has been addressed in Amazon.IonDotnet version 1.3.1. We recommend upgrading to the latest version and ensuring any forked or derivative code is patched to incorporate the new fixes.
Workarounds
There are no workarounds. Upgrade to version 1.3.1.
References
If you have any questions or comments about this advisory, contact AWS/Amazon Security via our vulnerability reporting page or directly via email to aws-security@amazon.com. Please do not create a public GitHub issue.
Credit
We would like to thank Josh Coleman from Symbotic for collaborating on this issue through the coordinated vulnerability disclosure process.

"details": "## Summary\n\n[Amazon.IonDotnet (ion-dotnet)](https://github.com/amazon-ion/ion-dotnet) is a .NET library with an implementation of the [Ion data serialization format](https://amazon-ion.github.io/ion-docs/).\n\nAn issue exists in Amazon.IonDotnet and the RawBinaryReader class where, under certain conditions, an actor could trigger an infinite loop condition.\n\n## Impact\n\nWhen reading binary Ion data through Amazon.IonDotnet using the RawBinaryReader class, Amazon.IonDotnet does not check the number of bytes read from the underlying stream while deserializing the binary format. If the Ion data is malformed or truncated, this triggers an infinite loop condition that could potentially result in a denial of service.\n\n**Impacted versions: \u003c=1.3.0**\n\n## Patches\n\nThis issue has been addressed in Amazon.IonDotnet version [1.3.1](https://github.com/amazon-ion/ion-dotnet/releases/tag/v1.3.1). We recommend upgrading to the latest version and ensuring any forked or derivative code is patched to incorporate the new fixes.\n\n## Workarounds\n\nThere are no workarounds. Upgrade to version 1.3.1.\n\n## References\n\nIf you have any questions or comments about this advisory, contact AWS/Amazon Security via our [vulnerability reporting page](https://aws.amazon.com/security/vulnerability-reporting) or directly via email to [aws-security@amazon.com](mailto:aws-security@amazon.com). Please do not create a public GitHub issue.\n\n## Credit\n\nWe would like to thank Josh Coleman from Symbotic for collaborating on this issue through the coordinated vulnerability disclosure process.",

Vulnerability from github – Published: 2024-09-13 15:31 – Updated: 2024-09-13 15:31The WP Editor plugin for WordPress is vulnerable to deserialization of untrusted input via the 'current_theme_root' parameter in versions up to, and including 1.2.9. This makes it possible for authenticated attackers with administrative privileges to call files using a PHAR wrapper that will deserialize and call arbitrary PHP Objects that can be used to perform a variety of malicious actions granted a POP chain is also present. It also requires that the attacker is successful in uploading a file with the serialized payload.

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.
