CVE-2026-54103
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 · uneditedThe U.S. Government Accountability Office (GAO) Electronic Protest Docketing System (EPDS) and Civilian Board of Contract Appeals (CBCA) Electronic Docketing System (EDS) does not authenticate password change requests to the '/update-profile/N' API endpoint. A remote, unauthenticated attacker could change an arbitrary user's password.
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 confidenceThe GAO Electronic Protest Docketing System (EPDS) and CBCA Electronic Docketing System (EDS) contain an authentication bypass vulnerability in the '/update-profile/N' API endpoint. The endpoint fails to verify user identity before processing password change requests, allowing any unauthenticated remote attacker to reset arbitrary user passwords by targeting known or enumerable user identifiers.

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 if your system is EPDS or EDSReview your installed applications or system documentation to confirm you are running the GAO Electronic Protest Docketing System or CBCA Electronic Docketing SystemAffected if Your environment runs either EPDS or EDS software
-
Verify the /update-profile/N endpoint existsCheck your web server logs or application routing configuration for requests to /update-profile/N or similar paths. This endpoint handles profile updates.Affected if The endpoint exists and is reachable in your application
-
Test endpoint authentication requirementSend a crafted request to /update-profile/N with a test user identifier and new password without including any authentication tokens, session cookies, or authorization headersAffected if The endpoint processes the request and returns success without requiring valid authentication
-
Check for missing user identity verificationInspect application logs for password change requests to /update-profile/N and verify whether the code validates the requesting user's identity before processingAffected if Password changes are processed without verifying the requester's identity
-
Review API security configurationExamine your application's authentication middleware, security filters, or web.config/permissions settings to determine if /update-profile/N is explicitly excluded from authentication checksAffected if The endpoint is excluded from authentication or lacks identity verification logic
-
Check for lack of CSRF protectionInspect the application's security configuration for CSRF token validation on the password change endpointAffected if No CSRF protection is enforced on the profile update endpoint
You are affected if your environment runs EPDS or EDS and the /update-profile/N endpoint processes password change requests without requiring valid authentication or identity verification.

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 dataImplement proper authentication and authorization checks on all password change endpoints, verify the requesting user's identity through session validation or token-based authentication, and add CSRF protection. Consider implementing rate limiting to prevent brute-force enumeration of user IDs.
