CVE-2019-3802
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedThis affects Spring Data JPA in versions up to and including 2.1.6, 2.0.14 and 1.11.20. ExampleMatcher using ExampleMatcher.StringMatcher.STARTING, ExampleMatcher.StringMatcher.ENDING or ExampleMatcher.StringMatcher.CONTAINING could return more results than anticipated when a maliciously crafted example value is supplied.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceSpring Data JPA's ExampleMatcher with STARTING, ENDING, or CONTAINING string matchers allows crafted example values to bypass query filters, returning more database records than intended and potentially exposing sensitive data.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify Spring Data JPA versionCheck your project's dependency management file (Maven pom.xml or Gradle build.gradle) for the spring-data-jpa artifact version, or inspect the spring-data-jpa-*.jar file in your runtime classpathAffected if The version falls within 1.11.0-1.11.21, 2.0.0-2.0.14, or 2.1.0-2.1.7
-
Locate ExampleMatcher usage in codebaseSearch source code for imports of org.springframework.data.domain.ExampleMatcher and usages of the ExampleMatcher classAffected if ExampleMatcher is used in the application code
-
Identify vulnerable StringMatcher typesSearch for method calls on ExampleMatcher instances such as .withStringMatcher(), .withStart(), .withEnd(), .contains(), or StringMatcher.STARTING, StringMatcher.ENDING, StringMatcher.CONTAININGAffected if Code uses ExampleMatcher with STARTING, ENDING, or CONTAINING StringMatcher types in query logic
You are affected if your Spring Data JPA version is within the vulnerable ranges AND your code uses ExampleMatcher with STARTING, ENDING, or CONTAINING string matchers.
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpgrade Spring Data JPA to versions 2.1.7, 2.0.15, or 1.11.21 or later. Audit existing code using ExampleMatcher with these StringMatcher types to ensure queries behave as expected after the upgrade.
