CVE-2026-14725: Boat Reservation System Auth Bypass Flaw

CVE-2026-14725 Overview

CVE-2026-14725 is an improper session invalidation vulnerability in SourceCodester Online Boat Reservation System 1.0. The flaw resides in an unspecified function that handles session state, allowing an attacker to manipulate session expiration behavior. The weakness maps to [CWE-613] Insufficient Session Expiration. Remote exploitation is possible, and a public write-up describing the issue has been released. The vulnerability affects the confidentiality, integrity, and availability of user sessions at a limited level.

Critical Impact
Attackers can abuse sessions that are not properly invalidated, potentially reusing authenticated session tokens against the Online Boat Reservation System web application over the network.

Affected Products

SourceCodester Online Boat Reservation System 1.0
PHP-based deployments of the Online Boat Reservation System
Any downstream forks reusing the vulnerable session handling logic

Technical Details for CVE-2026-14725

Vulnerability Analysis

The vulnerability is an improper session invalidation flaw in the Online Boat Reservation System 1.0. The application fails to correctly terminate or expire user sessions after specific events such as logout or credential change. As a result, session identifiers remain valid past their intended lifecycle. An attacker who obtains a session token, for example through shared devices, browser history, log exposure, or interception, can continue to interact with the application as the original user. The application classifies this as a session expiration weakness under [CWE-613]. The public Medium write-up describes the exact reproduction steps in the PHP-based codebase.

Root Cause

The root cause is missing or inadequate server-side session teardown. The PHP session state is not fully destroyed on logout, and session tokens are not rotated after authentication state changes. Because expiration is enforced weakly, previously issued session identifiers remain usable until the underlying session store garbage-collects them.

Attack Vector

The attack is delivered over the network and requires a low-privileged authenticated context. An attacker who acquires a valid session cookie can replay it against the application to access reservation functionality tied to the victim account. No user interaction is required beyond possessing the token. The public proof-of-concept material is referenced in the VulDB entries for this identifier.

No verified exploit code is published in a structured PoC repository. Refer to the Medium write-up on improper session invalidation and the VulDB CVE-2026-14725 record for reproduction details.

Detection Methods for CVE-2026-14725

Indicators of Compromise

Reuse of the same PHPSESSID cookie value across distinct source IP addresses or user-agent strings within a short window.
Authenticated requests to reservation endpoints occurring after a documented user logout event in application logs.
Session identifiers that persist longer than the configured server-side session lifetime.

Detection Strategies

Correlate logout events with subsequent HTTP requests carrying the same session cookie to identify token replay.
Baseline expected session durations for the Online Boat Reservation System and alert on sessions exceeding that duration.
Inspect web server and PHP session store logs for identifiers that appear after account password changes.

Monitoring Recommendations

Enable verbose authentication and session lifecycle logging in the PHP application and forward events to a central SIEM.
Monitor for anomalous geolocation or ASN changes tied to a single session identifier.
Track failed and repeated access attempts to reservation endpoints tied to accounts flagged as logged out.

How to Mitigate CVE-2026-14725

Immediate Actions Required

Restrict public exposure of the Online Boat Reservation System 1.0 until session handling is remediated.
Force logout of all active sessions and rotate session identifiers for every authenticated user.
Shorten server-side session lifetimes and enforce absolute session timeouts.

Patch Information

No vendor patch is referenced in the NVD entry for CVE-2026-14725. SourceCodester has not published a fixed release at the time of writing. Administrators should apply the workarounds below and monitor the SourceCodester project page and the VulDB entry for updates.

Workarounds

Modify the logout handler to call session_unset() and session_destroy(), then invalidate the session cookie in the client with an expired Set-Cookie header.
Regenerate session IDs on login and privilege changes using session_regenerate_id(true) to prevent token reuse.
Set the session.gc_maxlifetime, session.cookie_secure, and session.cookie_httponly PHP directives to enforce stricter session boundaries.
Place the application behind a reverse proxy or WAF that can enforce session inactivity timeouts independent of the application.

bash

# Configuration example: harden PHP session handling in php.ini
session.gc_maxlifetime = 900
session.cookie_lifetime = 0
session.cookie_secure = 1
session.cookie_httponly = 1
session.cookie_samesite = "Strict"
session.use_strict_mode = 1
