Common Weakness Enumeration

CWE-202

Weakness Allowed

Exposure of Sensitive Information Through Data Queries

Abstraction: Base · Status: Draft

API response cwe.mitre.org

When trying to keep information confidential, an attacker can often infer some of the information by using statistics.

Dimensions

  • Behavior-Type: Data Queries
  • Info-Type: Information
  • Info-Property: Sensitive
Mapping guidance

This CWE entry is at the Base level of abstraction, which is a preferred level of abstraction for mapping to the root causes of vulnerabilities.

Carefully read both the name and description to ensure that this mapping is an appropriate fit. Do not try to 'force' a mapping to a lower-level Base/Variant simply to comply with this preferred level of abstraction.

Maintenance

The relationship between CWE-202 and CWE-612 needs to be investigated more closely, as they may be different descriptions of the same kind of problem. CWE-202 is also being considered for deprecation, as it is not clearly described and may have been misunderstood by CWE users. It could be argued that this issue is better covered by CAPEC; an attacker can utilize their data-query privileges to perform this kind of operation, and if the attacker should not be allowed to perform the operation - or if the sensitive data should not have been made accessible at all - then that is more appropriately classified as a separate CWE related to authorization (see the parent, CWE-1230).

CVE-2026-106506 (GCVE-0-2026-106506)

Vulnerability from cvelistv5 – Published: 2026-10-06 21:44 – Updated: 2026-10-07 17:06

Title
Backstage: Improper input validation in scaffolder task list ordering
Summary
Backstage is an open framework for building developer portals. Prior to 4.1.0, the @backstage/plugin-scaffolder-backend package is affected by improper input validation in scaffolder task list ordering. An authenticated Backstage user with permission to create and read relevant scaffolder tasks may be able to infer confidential task data under specific conditions. Successful exploitation requires retained task secrets, visibility of a target task, knowledge of the secret structure, and repeated requests. This issue is fixed in version 4.1.0.

CVE-2026-105615 (GCVE-0-2026-105615)

Vulnerability from cvelistv5 – Published: 2026-10-28 17:31 – Updated: 2026-11-05 16:59

Title
PostgreSQL Anonymizer: Masked roles can read the statistics of masked columns in pg_stats
Summary
PostgreSQL's optimized statistics on a table are visible as long as you have SELECT privilege on said table. A masked role can therefore read a limited subset of the data through the statistics view's histograms and mcvs. The vulnerability is resolved in PostgreSQL Anonymizer 3.3.0 and later versions.
