CVE-2024-10451
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 · uneditedA flaw was found in Keycloak. This issue occurs because sensitive runtime values, such as passwords, may be captured during the Keycloak build process and embedded as default values in bytecode, leading to unintended information disclosure. In Keycloak 26, sensitive data specified directly in environment variables during the build process is also stored as a default values, making it accessible during runtime. Indirect usage of environment variables for SPI options and Quarkus properties is also vulnerable due to unconditional expansion by PropertyMapper logic, capturing sensitive data as default values in all Keycloak versions up to 26.0.2.
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 confidenceKeycloak inadvertently captures sensitive runtime values (passwords, secrets) during the build process and embeds them as default values in the compiled bytecode. The PropertyMapper unconditionally expands environment variables, including indirect usage for SPI options and Quarkus properties, causing sensitive data to be stored as accessible defaults in all versions up to 26.0.2.

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.
-
Check Keycloak versionRun 'keycloak --version' or check the version file in the Keycloak installation directoryAffected if version is 26.0.2 or lower
-
Inspect bytecode for embedded secretsSearch compiled .class files in the Keycloak distribution for strings matching passwords, secrets, or API keys that may have been in build-time environment variables using 'strings' or grep toolsAffected if sensitive values from environment variables appear as plaintext strings in compiled bytecode
-
Review environment variable usage at build timeExamine build logs, CI/CD configuration, or build scripts to identify which environment variables were set during the Keycloak build process, particularly those used for SPI options or Quarkus propertiesAffected if sensitive credentials or secrets were present in environment variables during build
-
Check PropertyMapper configurationInspect the Keycloak source or compiled classes for PropertyMapper implementation to determine if environment variable expansion is unconditionally applied to SPI and Quarkus property configurationsAffected if PropertyMapper processes environment variables without filtering for sensitive values
A user is affected if they built Keycloak version 26.0.2 or earlier while sensitive data (passwords, secrets) existed in environment variables, as such data may now be embedded in the compiled bytecode as accessible defaults.
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.
dbcve · scopedEnsure sensitive data is not present in environment variables during the Keycloak build process. Use runtime secret management mechanisms instead of embedding secrets at build time, and review all environment variable usage for SPI and Quarkus property configurations.
Keycloak 26.0.3 or later
- Upgrade Keycloak to version 26.0.3 or later, which contains the fix for this vulnerability
- After upgrading, verify that no sensitive environment variables or credentials are inadvertently embedded in configuration by reviewing build outputs
- If running in a container environment, rebuild container images using the updated Keycloak version to ensure no sensitive data persists in bytecode
