CVE-2026-8059
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 · uneditedIBM Datacap 9.1.7, 9.1.8, and 9.1.9 and IBM Datacap Navigator 9.1.7, 9.1.8, and 9.1.9 is vulnerable to cross-site scripting. This vulnerability allows an unauthenticated attacker to embed arbitrary JavaScript code in the Web UI thus altering the intended functionality potentially leading to credentials disclosure within a trusted session.
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 confidenceIBM Datacap and Datacap Navigator versions 9.1.7-9.1.9 contain a stored cross-site scripting (XSS) vulnerability in their Web UI. An unauthenticated attacker can embed malicious JavaScript code that executes within the context of a trusted user session, potentially allowing credential theft or session hijacking.

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 installed IBM Datacap productLocate the Datacap installation directory or check installed programs on the system. Look for IBM Datacap or IBM Datacap Navigator in the system registry or installed applications list.Affected if IBM Datacap or IBM Datacap Navigator is present on the system
-
Determine installed versionCheck the product version through the Datacap administration interface, installation logs, or by querying the installed package version. Common locations include the program files directory or Windows registry under IBM entries.Affected if The version number matches 9.1.7, 9.1.8, or 9.1.9
-
Verify Web UI is accessibleConfirm that the Datacap Web UI service is running and accessible. Attempt to reach the web interface URL (typically on port 8080, 8443, or configured custom port).Affected if The Web UI is exposed and accepts user input
-
Review web application logs for suspicious inputExamine Datacap web server logs and application logs for any unusual JavaScript tags, script elements, or encoded XSS payloads in user-submitted fields.Affected if Log entries contain unsanitized script tags or XSS probe patterns in user input fields
A user is affected if they have IBM Datacap or Datacap Navigator version 9.1.7, 9.1.8, or 9.1.9 running with the Web UI enabled and accessible.

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 output encoding and input validation for all user-supplied data in the Web UI. Apply context-specific sanitization and consider deploying a WAF rule to block XSS payloads until a vendor patch is available.
