CVE-2026-8636
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 allows an attacker to retrieve user passwords and cryptographic keys from memory. Attacker can use the same keys to decrypt password, gain access to the application and access sensitive data in the database.
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 through 9.1.9 contain a memory exposure vulnerability that allows attackers to retrieve user passwords and cryptographic keys directly from process memory. The exposed cryptographic keys can then be used to decrypt stored passwords, enabling unauthorized access to the application and sensitive data in connected databases.

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 versionUse the IBM Datacap version reporting mechanism or check the product's about/ license information panel to determine the exact version numberAffected if The installed version is 9.1.7, 9.1.8, or 9.1.9
-
Identify installed IBM Datacap Navigator versionAccess the Datacap Navigator application or check its installation directory for version informationAffected if The installed version is 9.1.7, 9.1.8, or 9.1.9
-
Verify application is running and accessibleConfirm the Datacap and Datacap Navigator services are active and the web interface or API endpoints are reachableAffected if The application is running and accessible to users or network attackers
You are affected if either IBM Datacap or IBM Datacap Navigator is installed and running at version 9.1.7, 9.1.8, or 9.1.9, because these versions contain the memory exposure vulnerability that could allow attackers to retrieve credentials from process memory.

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 dataApply IBM patches for Datacap 9.1.7-9.1.9 and Datacap Navigator 9.1.7-9.1.9 as soon as they are released. Immediately rotate all credentials that may have been exposed and review access logs for indicators of exploitation prior to patching.
