CVE-2025-59797: Profession Fit Auth Bypass Vulnerability

CVE-2025-59797 Overview

CVE-2025-59797 is an authorization bypass vulnerability in Profession Fit version 5.0.99 Build 44910. The application fails to enforce access controls on several endpoints, allowing unauthenticated attackers to reach protected resources through direct requests. Affected paths include /api/challenges/{id}, the eversports integration URLs, the user-management page, and the plane page. The weakness is classified under [CWE-425] (Direct Request, also known as Forced Browsing). Successful exploitation exposes information intended for authorized users only, without requiring credentials or user interaction.

Critical Impact
Remote attackers can access restricted application resources by issuing direct HTTP requests, bypassing intended authorization checks and disclosing user and administrative data.

Affected Products

Technical Details for CVE-2025-59797

Vulnerability Analysis

The vulnerability stems from missing server-side authorization checks on multiple endpoints of the Profession Fit web application. The application relies on client-side navigation or obscurity to protect sensitive pages and API routes. Attackers who know or guess the endpoint paths can retrieve data by sending unauthenticated HTTP requests directly to those URLs.

The issue affects both a REST API endpoint at /api/challenges/{id} and several page-based routes, including the eversports integration URLs, the user-management page, and the plane page. Because authorization is not enforced at the server, session tokens and role checks are effectively optional for these paths. The confidentiality impact is limited to information disclosure, with no direct effect on integrity or availability, according to the assigned CVSS vector.

Root Cause

The root cause is a Direct Request weakness [CWE-425]. The application exposes resources through predictable URL patterns without validating that the requesting user has permission to access each resource. Authorization logic is either absent, applied only in the UI layer, or bypassable by omitting the standard navigation flow.

Attack Vector

An unauthenticated remote attacker sends crafted HTTP GET requests to the vulnerable endpoints. For the API endpoint, the attacker iterates numeric or predictable {id} values against /api/challenges/{id} to enumerate challenge records. For the user-management, plane, and eversports pages, the attacker requests the URLs directly and receives content that should require an authenticated session with appropriate privileges. No user interaction, tokens, or preconditions are required beyond network reachability to the application.

Detection Methods for CVE-2025-59797

Indicators of Compromise

Unauthenticated HTTP requests to /api/challenges/{id} returning HTTP 200 with data payloads.
Sequential enumeration patterns targeting the {id} parameter from a single source IP.
Requests to the user-management, plane, or eversports URLs without a preceding authenticated session cookie.
Web server access logs showing direct hits on protected paths bypassing the normal login and navigation flow.

Detection Strategies

Compare authenticated versus unauthenticated response codes and body sizes for sensitive endpoints to identify missing authorization enforcement.
Alert on high-volume ID enumeration against /api/challenges/{id} from a single client within a short time window.
Correlate requests to administrative pages such as user-management with the absence of prior authentication events in application logs.

Monitoring Recommendations

Ingest Profession Fit web and API access logs into a central log platform and retain them for retrospective hunting.
Baseline normal request rates to /api/challenges/{id} and the user-management, plane, and eversports pages, then alert on deviations.
Track HTTP responses that return sensitive fields to sessions without valid authentication cookies or tokens.

How to Mitigate CVE-2025-59797

Immediate Actions Required

Restrict network access to the Profession Fit application to trusted networks or VPN users until a vendor patch is applied.
Place the affected endpoints behind a web application firewall rule that requires an authenticated session cookie for /api/challenges/, user-management, plane, and eversports URLs.
Review web server logs for prior unauthenticated access to the affected paths and treat any findings as potential data disclosure incidents.

Patch Information

No vendor patch reference is listed in the NVD entry at the time of publication. Contact the vendor through the Profession Fit Company Website for a fixed release and upgrade guidance. Monitor the GitHub CVE-2025-59797 Overview for updates from the reporter.

Workarounds

Enforce authentication and authorization at a reverse proxy in front of Profession Fit for all endpoints listed in the advisory.
Block direct external access to /api/challenges/{id} and require requests to originate from authenticated application sessions.
Randomize or hash resource identifiers so {id} values cannot be enumerated sequentially by an unauthenticated attacker.

bash

# Example NGINX reverse proxy rule requiring an authenticated session cookie
location ~ ^/(api/challenges/|user-management|plane|eversports) {
    if ($cookie_session = "") {
        return 401;
    }
    proxy_pass http://profession_fit_backend;
}
