CVE-2020-26219
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 · uneditedtouchbase.ai before version 2.0 is vulnerable to Open Redirect. Impacts can be many, and vary from theft of information and credentials, to the redirection to malicious websites containing attacker-controlled content, which in some cases even cause XSS attacks. So even though an open redirection might sound harmless at first, the impacts of it can be severe should it be exploitable. The issue is fixed in version 2.0.
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 confidencetouchbase.ai before version 2.0 contains an open redirect vulnerability where the application fails to properly validate redirect URLs, allowing attackers to craft malicious URLs that redirect users to arbitrary external sites. This can be exploited for credential theft, phishing attacks, and in some cases to chain with XSS vulnerabilities.

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.
-
Determine Touchbase.ai installed versionLocate the version information for your Touchbase.ai installation. Check application files, configuration files, or the web interface for a version number or build identifier.Affected if installed version is less than 2.0 (for example, version 1.x or any version number below 2.0)
-
Identify redirect-enabled endpointsReview application URLs and parameters that handle redirection. Common patterns include parameters named 'redirect', 'url', 'next', 'dest', or 'target'. Check login, logout, and callback pages for redirect functionality.Affected if the application processes user-controlled input as redirect targets and allows arbitrary URLs
-
Test redirect parameter validationCraft a test URL using the redirect parameter with an external domain (for example, appending '?redirect=https://example.com' to a Touchbase.ai URL). Observe whether the application allows redirection to the external site or properly validates against an allowlist.Affected if the application redirects to the external domain instead of rejecting or limiting to internal URLs
-
Check redirect configurationInspect application configuration files or settings for redirect validation rules. Look for allowlists, whitelists, or validation logic governing where users can be redirected.Affected if no redirect validation or allowlist is configured, allowing unrestricted redirect targets
You are affected if your Touchbase.ai version is below 2.0 and the application exposes redirect functionality that accepts unvalidated external URLs.

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 data2.0
Upgrade to version 2.0 or later. Implement strict validation of redirect parameters to ensure they only allow trusted, internal URLs (allowlist approach).
