CVE-2026-14465 Overview
CVE-2026-14465 is an insufficient session expiration vulnerability in Bilin Software and Informatics Consultancy Inc. HUMANIST Digital Human Resources. The flaw allows attackers to reuse valid session identifiers after they should have been invalidated, enabling session replay attacks. The issue affects HUMANIST Digital Human Resources versions from 26.0 before 26.1. The vulnerability is categorized under [CWE-613] Insufficient Session Expiration and is exploitable over the network with low attack complexity, requiring user interaction. Successful exploitation impacts confidentiality by exposing sensitive human resources data accessible through hijacked sessions.
Critical Impact
Attackers who obtain a previously valid session identifier can replay it to gain unauthorized access to a user's HUMANIST HR account, exposing personnel data.
Affected Products
- Bilin Software and Informatics Consultancy Inc. HUMANIST Digital Human Resources 26.0
- HUMANIST Digital Human Resources versions from 26.0 before 26.1
- Fixed in HUMANIST Digital Human Resources 26.1

Technical Details for CVE-2026-14465
Vulnerability Analysis
The vulnerability resides in how HUMANIST Digital Human Resources manages authenticated session lifecycles. Session identifiers issued by the application remain valid beyond the point where they should be invalidated, such as after logout, timeout, or credential change. An attacker who captures a session identifier can replay it to authenticate as the original user without needing credentials. This class of flaw, tracked as [CWE-613], creates a persistent window for account takeover after session material is exposed through logs, referer headers, shared devices, or network interception. The impact is limited to confidentiality, meaning integrity and availability of the HR platform are not directly affected by exploitation.
Root Cause
The root cause is improper session lifecycle management in HUMANIST Digital Human Resources releases before 26.1. Session tokens are not sufficiently expired or rotated by the server, allowing prior identifiers to remain accepted as valid credentials. Without a strict server-side expiration policy, stolen or leaked session identifiers grant continued access.
Attack Vector
Exploitation requires network access to the HUMANIST application and some form of user interaction, such as a victim visiting an attacker-controlled resource that harvests session data. Once a valid session identifier is captured, the attacker replays it against the application's authenticated endpoints. No privileges are required prior to exploitation. Refer to the Siber Güvenlik Notification TR-26-0737 for vendor-referenced technical detail.
Detection Methods for CVE-2026-14465
Indicators of Compromise
- Repeated authenticated requests to HUMANIST endpoints using the same session identifier from multiple distinct IP addresses or user agents.
- Authenticated activity on a session identifier after the associated user has explicitly logged out.
- Session identifiers observed in web server logs long after their expected expiration window.
Detection Strategies
- Correlate application access logs to identify session identifiers reused across disparate geolocations or client fingerprints.
- Alert on authenticated HTTP requests carrying session cookies that should have been invalidated by a logout event.
- Baseline normal session duration for HUMANIST users and flag sessions that persist substantially longer than the norm.
Monitoring Recommendations
- Ingest HUMANIST web server and application logs into a centralized analytics platform for session correlation.
- Monitor for anomalous access patterns tied to HR data endpoints, especially employee records and payroll views.
- Track user-agent and source IP changes within a single active session as a high-fidelity replay signal.
How to Mitigate CVE-2026-14465
Immediate Actions Required
- Upgrade HUMANIST Digital Human Resources to version 26.1 or later, which addresses the insufficient session expiration flaw.
- Force logout of all active HUMANIST user sessions after upgrading to invalidate any pre-existing session identifiers.
- Rotate any shared secrets or session signing keys used by the HUMANIST application if the platform supports it.
Patch Information
Bilin Software addresses CVE-2026-14465 in HUMANIST Digital Human Resources 26.1. Administrators should consult the Siber Güvenlik Notification TR-26-0737 advisory and coordinate with the vendor for the upgrade package and release notes.
Workarounds
- Reduce server-side session timeout values at any reverse proxy or web server layer fronting HUMANIST to shorten the exposure window.
- Enforce short-lived authentication cookies with Secure, HttpOnly, and SameSite=Strict attributes to limit session capture.
- Restrict HUMANIST access to trusted networks or VPN-connected clients until the 26.1 upgrade is deployed.
- Require users to re-authenticate for sensitive HR operations to limit the value of a replayed session.
