CWE-1108 (Excessive Reliance on Global Variables) is a base-level software weakness catalogued by MITRE in the Common Weakness Enumeration (CWE). It describes a recurring type of mistake that can lead to exploitable security vulnerabilities.
2 recorded CVEs are caused by CWE-1108 (Excessive Reliance on Global Variables). The highest-severity and most recent are shown first. 1 new CWE-1108 CVE has been recorded so far in 2026.
What can happen when CWE-1108 is exploited.
Reduce Maintainability, Increase Analytical Complexity
Affects: Other
This issue makes it more difficult to maintain the product, which indirectly affects security by making it more difficult or time-consuming to find and/or fix vulnerabilities. It also might make it easier to introduce vulnerabilities.
Typically introduced during these phases of the software lifecycle.
Automated static analysis, commonly referred to as Static Application Security Testing (SAST), can find some instances of this weakness by analyzing source code (or binary/compiled code) without having to execute it. Typically, this is done by building a model of data flow and control flow, then searching for potentially-vulnerable patterns that connect "sources" (origins of input) with "sinks" (destinations where the data interacts with external components, a lower layer such as the OS, etc.)
Effectiveness: High
