GHSA-3QPM-H9CH-PX3C
Vulnerability from github – Published: 2022-01-06 18:31 – Updated: 2022-01-04 22:06Summary
The version used of Log4j, the library used for logging by PowerNukkit, is subject to a remote code execution vulnerability via the ldap JNDI parser. It's well detailed at CVE-2021-44228 and CVE-2021-45105(https://github.com/advisories/GHSA-p6xc-xr62-6r2g).
Impact
Malicious client code could be used to send messages and cause remote code execution on the server.
Patches
PowerNukkit 1.5.2.1 is a patch-release that only updates the Log4j version to 2.17.0 and should be used instead of 1.5.2.0.
All versions prior to 1.5.2.1 are affected and are not patched.
Workarounds
If you can't upgrade, you can use the -Dlog4j2.formatMsgNoLookups=true startup argument as remediation, as this prevents the vulnerability from happening.

GHSA-3RXJ-6CGF-8CFW
Vulnerability from github – Published: 2026-01-21 15:41 – Updated: 2026-01-22 15:39Improper input handling in the JSON deserialization component can lead to arbitrary JavaScript code execution.
The vulnerability can be exploited via overriding constant value and error deserialization, which allows indirect access to unsafe JS evaluation. This requires at least the ability to perform 4 separate requests on the same function and partial knowledge of how the serialized data is used during later runtime processing.
This vulnerability affects the fromJSON and fromCrossJSON functions in a client-to-server transmission scenario.
No known workarounds or mitigations are known, so please upgrade to the patched version.

}
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.
