Taiga is an open source project management platform. In versions 6.8.3 and earlier, a remote code execution vulnerability exists in the Taiga API due to unsafe deserialization of untrusted data. This issue is fixed in version 6.9.0.
Weakness
The product deserializes untrusted data without sufficiently ensuring that the resulting data will be valid.
Potential Mitigations
- 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.
