DEPRECATED: State Synchronization Error
This entry has been retired because its core concept—errors that occur when different parts of a system fail to coordinate their shared state correctly—is fully covered by two more precise and actively maintained categories: Race Conditions (CWE-362) and Improper Synchronization (CWE-662).
State synchronization errors happen when concurrent processes or threads access shared resources—like variables, files, or memory—without proper coordination. This can lead to unpredictable behavior, corrupted data, or security vulnerabilities because the system's state becomes inconsistent depending on the timing of operations. Developers should look to the more specific and detailed guidance provided under race conditions and improper synchronization for modern analysis. Instead of using this deprecated entry, security researchers and developers should reference CWE-362 (Concurrent Execution using Shared Resource with Improper Synchronization, or 'Race Condition') and CWE-662 (Improper Synchronization). These entries provide clearer frameworks for identifying, preventing, and mitigating issues where a system's components fail to manage shared state safely, which is the essential concept this entry aimed to describe.
