Improper Control of Dynamically-Identified Variables
CWE-914
Per technology (GHSA, All time)
100%-Pip
Short description
The product does not properly restrict reading from or writing to dynamically-identified variables.
Extended description
Many languages offer powerful features that allow the programmer to access arbitrary variables that are specified by an input string. While these features can offer significant flexibility and reduce development time, they can be extremely dangerous if attackers can modify unintended variables that have security implications.
Best practices to prevent this CWE
Phase: Implementation
Strategy: Input Validation
For any externally-influenced input, check the input against an allowlist of internal program variables that are allowed to be modified.
Phase: Implementation; Architecture and Design
Strategy: Refactoring
Refactor the code so that internal program variables do not need to be dynamically identified.
