The code transmits data to another actor, but a portion of the data includes sensitive information that should not be accessible to that actor.
View on MITRESensitive data may be exposed to attackers.
Specify which data in the software should be regarded as sensitive. Consider which types of users should have access to which types of data.
Ensure that any possibly sensitive data specified in the requirements is verified with designers to ensure that it is either a calculated risk or mitigated elsewhere. Any information that is not necessary to the functionality should be removed in order to lower both the overhead and the possibility of security sensitive data being sent.
Setup default error messages so that unexpected errors do not disclose sensitive information.

CWE-201: Insertion of Sensitive Information Into Sent Data is a Common Weakness Enumeration (CWE) entry maintained by MITRE. The code transmits data to another actor, but a portion of the data includes sensitive information that should not be accessible to that actor.
If exploited, CWE-201 (Insertion of Sensitive Information Into Sent Data) it can compromise Confidentiality, leading to outcomes such as Read Files or Directories, Read Memory and Read Application Data.
Recommended mitigations for CWE-201 include: Specify which data in the software should be regarded as sensitive. Consider which types of users should have access to which types of data. Ensure that any possibly sensitive data specified in the requirements is verified with designers to ensure that it is either a calculated risk or mitigated elsewhere. Any information that is not necessary to the functionality should be removed in order to lower both the overhead and the possibility of security sensitive data being sent. Setup default error messages so that unexpected errors do not disclose sensitive information.
CWE-201 commonly affects Not Language-Specific. Note that weaknesses are often language-agnostic patterns, so secure coding practices apply broadly.
MITRE documents real CVEs mapped to CWE-201, including CVE-2022-0708. You can look up the full details of each CVE, including CVSS scores and remediation guidance, on our CVE Lookup tool.
A CWE (Common Weakness Enumeration) like CWE-201 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.
