func CheckObjectName ¶ added in v1.6.0

func CheckObjectName(objectName string) bool

CheckObjectName This code block checks for unsupported or potentially risky formats in object names. The checks are essential for ensuring the security and compatibility of the object names within the system. 1. ".." in object names: Checked to prevent path traversal attacks which might access directories outside the intended scope. 2. Object name being "/": The root directory should not be used as an object name due to potential security risks and ambiguity. 3. "\\" in object names: Backslashes are checked because they are often not supported in UNIX-like file systems and can cause issues in path parsing. 4. SQL Injection patterns in object names: Ensures that the object name does not contain patterns that could be used for SQL injection attacks, maintaining the integrity of the database.
