CVE-2025-56423
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 · uneditedAn issue in Austrian Academy of Sciences (AW) Austrian Archaeological Institute OpenAtlas v.8.12.0 allows a remote attacker to obtain sensitive information via the login error messages
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 confidenceOpenAtlas v8.12.0 contains an information disclosure vulnerability where verbose login error messages reveal sensitive information to remote attackers. This allows user enumeration or exposure of account details through the authentication error response.
Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

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 the installed OpenAtlas versionLocate the version information in the OpenAtlas application (typically in an about page, configuration file, or by querying the application metadata)Affected if The installed version is lower than 8.12.1
-
Review authentication error message configurationExamine the application configuration files or settings related to authentication error handling to determine if verbose error messages are enabledAffected if Verbose or detailed error messages are configured for failed login attempts
-
Test login error response with invalid credentialsAttempt to log in with a clearly incorrect username and/or password, then observe the exact text and content of the returned error messageAffected if The error message reveals whether the username exists versus whether the password is incorrect, rather than providing a generic authentication failure message
You are affected if your OpenAtlas version is below 8.12.1 AND the login error responses expose specific information about account validity rather than using generic authentication failure messages.

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 · scoped8.12.1
Implement generic error messages for authentication failures that do not indicate whether the username or password is incorrect, preventing user enumeration and information disclosure.
OpenAtlas 8.12.1 or later
- Obtain OpenAtlas version 8.12.1 or later from the official source
- Apply the upgrade following the standard OpenAtlas upgrade procedure
- Verify that the login error messages no longer disclose sensitive information
- Test that normal authentication functionality continues to work correctly
