CWE-1047: Modules with Circular Dependencies
The product contains modules in which one module has references that cycle back to itself, i.e., there are circular dependencies.
View on MITREExtended Description
As an example, with Java, this weakness might indicate cycles between packages. This issue makes it more difficult to maintain the product due to insufficient modularity, 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. This issue can prevent the product from running reliably. If the relevant code is reachable by an attacker, then this reliability problem might introduce a vulnerability.

Frequently Asked Questions
What is CWE-1047: Modules with Circular Dependencies?+
CWE-1047: Modules with Circular Dependencies is a Common Weakness Enumeration (CWE) entry maintained by MITRE. The product contains modules in which one module has references that cycle back to itself, i.e., there are circular dependencies. As an example, with Java, this weakness might indicate cycles between packages. This issue makes it more difficult to maintain the product due to insufficient modularity, 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. This issue can prevent the product from running reliably. If the relevant code is reachable by an attacker, then this reliability problem might introduce a vulnerability.
What are the security consequences of Modules with Circular Dependencies?+
If exploited, CWE-1047 (Modules with Circular Dependencies) it can compromise Other, leading to outcomes such as Reduce Reliability.
What is the difference between a CWE and a CVE?+
A CWE (Common Weakness Enumeration) like CWE-1047 describes a category of software weakness — the underlying flaw type. A CVE (Common Vulnerabilities and Exposures) identifies a specific, real-world vulnerability in a particular product. In short, a CWE is the kind of mistake, and a CVE is an instance of that mistake being found in software.
