CVE-2026-1989
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 · uneditedAuthorization bypass through User-Controlled key vulnerability in PAVO Financial Technology Solutions Inc. PAVO Pay allows Exploitation of Trusted Identifiers. This issue affects PAVO Pay: through 09072026. NOTE: The vendor was contacted early about this disclosure but did not respond in any way.
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 · moderate confidenceAuthorization bypass vulnerability in PAVO Pay where user-controlled keys enable exploitation of trusted system identifiers. Attackers can manipulate user-supplied key values to bypass authorization checks and access functions or data they should not have permission to access.

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 PAVO Pay installationSearch for PAVO Pay application files, services, or binaries on the system. Check common installation directories and verify the application name matches 'PAVO Pay' or related components.Affected if PAVO Pay is installed on the system
-
Determine PAVO Pay versionLocate version information through application metadata, configuration files, or executable version details. Compare against any available version documentation from the vendor.Affected if The installed version cannot be determined or is within an affected range (if ranges become known)
-
Locate authorization module configurationSearch for configuration files related to authentication and authorization in PAVO Pay installation directories. Look for files handling key validation, session management, or permission checks.Affected if Authorization configuration files exist and use user-supplied keys for access decisions
-
Identify user-controlled key handling codeInspect application code or configuration for endpoints, functions, or parameters that accept user-supplied keys or identifiers used in authorization logic. Search for patterns where user input directly influences access control decisions.Affected if User-controllable key values are accepted and used without server-side validation for sensitive operations
-
Check for exposed API endpoints accepting keysReview API routes, endpoints, or service interfaces that handle authorization. Identify if user-supplied key parameters are passed to functions that grant access to data or functions.Affected if Exposed endpoints accept user keys that are trusted for authorization without proper validation
The environment is affected if PAVO Pay is installed and user-supplied key values are accepted and trusted by the authorization system without server-side validation.

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 dataSince vendor did not respond, implement server-side validation of all user-controlled identifiers, replace user-controllable keys with server-generated cryptographically secure tokens, and enforce proper authorization checks on all sensitive operations.
