CWE-1024: Comparison of Incompatible Types is a Common Weakness Enumeration (CWE) entry maintained by MITRE. The product performs a comparison between two entities, but the entities are of different, incompatible types that cannot be guaranteed to provide correct results when they are directly compared.
If exploited, CWE-1024 (Comparison of Incompatible Types) it can compromise Other, leading to outcomes such as Varies by Context.
CWE-1024 can be detected using Manual Static Analysis. Combining automated tooling with manual review typically yields the best coverage.
CWE-1024 commonly affects JavaScript, PHP and Not Language-Specific. Note that weaknesses are often language-agnostic patterns, so secure coding practices apply broadly.
A CWE (Common Weakness Enumeration) like CWE-1024 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.
