Title
SolidInvoice: PHP unserialize() called on client-controlled data in DataGrid LiveComponent context prop
Summary
SolidInvoice is an open-source invoicing platform. Prior to version 3.0.1, the `DataGrid` LiveComponent deserializes a `context` prop value using PHP's `unserialize()` after receiving it from the client. Because the prop is marked `writable: true`, an authenticated attacker can supply an arbitrary PHP serialized payload. Version 3.0.1 fixes the issue.

Apache Lucy: LucyX::Remote::SearchServer unauthenticated remote Storable::thaw -> RCE/DoS
Summary
** UNSUPPORTED WHEN ASSIGNED ** Deserialization of Untrusted Data vulnerability in Apache Lucy.
This issue affects Apache Lucy: all versions.
As this project is retired, we do not plan to release a version that fixes this issue. Users are recommended to find an alternative or restrict access to the instance to trusted users.
Lucy is now maintained outside of the ASF at https://github.com/lucysearch . 0.8.0 is no longer affected by this issue, because the offending feature has been removed there.
NOTE: This vulnerability only affects products that are no longer supported by the maintainer.

Title
Seroval: `seroval.fromJSON()` Promise resolver type confusion invokes attacker-controlled methods during deserialization
Summary
Seroval facilitates JS value stringification, including complex structures beyond JSON.stringify capabilities. Prior to 1.5.3, seroval.fromJSON() allows attacker-controlled JSON Promise control nodes to operate on values from the general deserialization reference table without verifying genuine internal Promise resolver records, causing deserialization side effects with plugins enabled and potentially unintended server-side invocation or remote code execution when downstream frameworks register callable wrappers. This issue is fixed in version 1.5.3.

Metabase: Unsafe Deserialization of H2 Query Results
Summary
Metabase is an open-source business intelligence and embedded analytics tool. Prior to 1.58.15, 1.59.12, 1.60.6.3, and 1.61.1.4, Metabase instances with an H2 database connection, including the default sample database, deserialize arbitrary Java objects returned in H2 native query result columns of type OTHER without validation, allowing an authenticated user who can run native H2 queries to execute code on the Metabase server. This issue is fixed in versions 1.58.15, 1.59.12, 1.60.6.3, and 1.61.1.4.

Title
Apache Airflow: Arbitrary airflow.* class instantiation on the API server via the XCom deserialize endpoint
Summary
Apache Airflow's XCom `GET /api/v2/{...}/xcomEntries/{key}?deserialize=true` endpoint passed a string-literal payload through `BaseXCom.deserialize_value` without the `_check_forbidden_xcom_keys` guard, allowing an authenticated API user with XCom write-and-read access to instantiate arbitrary `airflow.*` classes on the API server (CWE-502). An authenticated user who can write an XCom value and then read it back with `deserialize=true` triggers the unsafe instantiation. Users are advised to upgrade to apache-airflow 3.3.1 or later, which rejects reserved XCom serialization keys submitted as JSON string literals.

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.
