CVE-2026-14903 Overview
CVE-2026-14903 is a path traversal vulnerability [CWE-23] affecting Ivanti Xtraction before version 2026.2.1. A remote authenticated attacker can read arbitrary files outside the web root by supplying crafted path sequences to a vulnerable endpoint. The flaw enables disclosure of sensitive server-side content, including configuration files, credentials, and application data accessible to the Xtraction service account.
The vulnerability requires network access and low-privilege authentication. Successful exploitation impacts confidentiality without directly modifying data or affecting availability. Ivanti published a security advisory addressing this issue alongside CVE-2026-14902.
Critical Impact
Authenticated remote attackers can read arbitrary files on the underlying host, exposing credentials and configuration data that support further compromise.

Technical Details for CVE-2026-14903
Vulnerability Analysis
CVE-2026-14903 is a relative path traversal weakness in Ivanti Xtraction. The application accepts a file or resource identifier from an authenticated user but fails to canonicalize the value before resolving it on disk. An attacker can inject ../ sequences to escape the intended directory and reach files elsewhere on the filesystem.
Because the scope changes when the flaw is triggered, the attacker can access resources beyond the boundary of the vulnerable component. The confidentiality impact is high, while integrity and availability are not directly affected. The Common Weakness Enumeration classification is [CWE-23] Relative Path Traversal.
EPSS data published on 2026-07-20 lists this issue with a probability of 1.037%, reflecting limited but non-trivial exploitation interest at the time of scoring.
Root Cause
The root cause is insufficient input validation on a file path parameter. Xtraction resolves the user-supplied value against a base directory without stripping traversal sequences or verifying that the canonical target remains within the expected root. Any authenticated session with access to the vulnerable endpoint can therefore reference files outside the web root.
Attack Vector
Exploitation occurs over the network against the Xtraction web interface. The attacker must first authenticate with a low-privilege account, then submit a request containing a path such as ../../../../etc/passwd or a Windows equivalent like ..\..\..\Windows\win.ini. The server returns the contents of the referenced file. Refer to the Ivanti Security Advisory for CVE-2026-14902 and CVE-2026-14903 for vendor guidance.
No public proof-of-concept exploit code is available at this time. The vulnerability mechanism is described in prose because verified exploitation examples have not been published.
Detection Methods for CVE-2026-14903
Indicators of Compromise
- HTTP requests to Xtraction endpoints containing ../, ..\, %2e%2e%2f, or %2e%2e%5c sequences in query strings or body parameters.
- Application or web server logs showing successful responses to requests referencing files outside the Xtraction install directory.
- Authenticated sessions accessing an unusual number of distinct file-fetching endpoints in a short window.
Detection Strategies
- Inspect Xtraction access logs for encoded and unencoded traversal patterns in parameters that map to file resources.
- Correlate authentication events with subsequent anomalous file access to identify low-privilege accounts abusing the endpoint.
- Deploy web application firewall signatures that flag path traversal attempts targeting Ivanti Xtraction URI paths.
Monitoring Recommendations
- Alert on any 200-response served for requests containing traversal metacharacters against Xtraction hosts.
- Monitor for reads of sensitive OS files such as /etc/passwd, /etc/shadow, web.config, or appsettings.json by the Xtraction service account.
- Track outbound data volume from Xtraction servers to detect bulk file exfiltration following successful traversal.
How to Mitigate CVE-2026-14903
Immediate Actions Required
- Upgrade Ivanti Xtraction to version 2026.2.1 or later as published in the vendor advisory.
- Audit Xtraction user accounts and disable any inactive or unnecessary low-privilege accounts that could be leveraged for authenticated access.
- Review web server and application logs for historical traversal patterns to determine whether exploitation has already occurred.
Patch Information
Ivanti addressed CVE-2026-14903 in Xtraction version 2026.2.1. Full details, including upgrade instructions, are available in the Ivanti Security Advisory for CVE-2026-14902 and CVE-2026-14903.
Workarounds
- Restrict network access to the Xtraction web interface to trusted management networks until the patch is applied.
- Enforce strong authentication and enable multi-factor authentication for all Xtraction accounts to reduce the risk of credential-based access.
- Configure a web application firewall to block requests containing path traversal sequences against Xtraction URIs.
