CVE-2020-26219: Open Redirect in touchbase.ai

touchbase.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.

Security readout for executives and security teams

Plain-English summary

touchbase.ai before 2.0 could redirect users to attacker-controlled sites. That can support phishing, credential theft, or malicious content delivery if a user follows a crafted link. The vendor states the issue is fixed in version 2.0.

Executive priority

Treat as a moderate phishing-enablement risk. Prioritize remediation where touchbase.ai is internet-facing, used in login-adjacent workflows, or trusted by customers and employees.

Technical view

CVE-2020-26219 is a CWE-601 open redirect in puncsky touchbase.ai versions before 2.0. CVSS 3.1 is 4.7, with network attack vector, high complexity, no privileges required, and user interaction required.

Likely exposure

Exposure is limited to deployments using touchbase.ai before version 2.0, especially public-facing flows where users may receive or click application links.

Exploitation context

The source bundle does not cite active exploitation, and this CVE is not listed as KEV. Practical abuse requires user interaction and likely social engineering, but impact can include credential theft or redirection to malicious content.

Researcher notes

Evidence is limited to the CVE record and GitHub advisory. No affected CPEs, exploit details, or KEV listing are provided. Validate version exposure and redirect controls without assuming broader product impact.

Mitigation direction

  • Upgrade touchbase.ai to version 2.0 or later.
  • Review vendor advisory for any additional upgrade guidance.
  • Restrict redirect destinations to approved internal or trusted domains.
  • Educate users to treat unexpected touchbase.ai links cautiously.

Validation and detection

  • Inventory deployed touchbase.ai versions across production and staging.
  • Confirm no deployment runs a version older than 2.0.
  • Review redirect-related application flows for approved-domain enforcement.
  • Check logs for unusual outbound redirect patterns, if available.
