CVE-2025-2204: XSS in Tapandsign Technologies' Tap&Sign App
Improper Neutralization of Input During Web Page Generation (XSS or 'Cross-site Scripting') vulnerability in Tapandsign Technologies Software Inc. Tap&Sign allows Cross-Site Scripting (XSS).
This issue affects Tap&Sign: through 23012026.
NOTE: The vendor was contacted early about this disclosure but did not respond in any way.
Security readout for executives and security teams
Plain-English summary
Tap&Sign has a cross-site scripting flaw that could let a highly privileged attacker place unwanted script content into generated web pages. The published severity is medium, but the vendor reportedly did not respond, and no fix is named in the provided sources.
Executive priority
Treat this as a targeted remediation item, not an emergency broad-internet event. Prioritize if Tap&Sign supports sensitive signing workflows, is externally reachable, or has many privileged users. Lack of vendor response increases follow-up importance.
Technical view
CVE-2025-2204 is a CWE-79 XSS issue in Tapandsign Technologies Software Inc. Tap&Sign, reported as affecting Tap&Sign through 23012026. CVSS 3.1 is 4.7: network reachable, low attack complexity, high privileges required, no user interaction, unchanged scope, and low confidentiality, integrity, and availability impact.
Likely exposure
Exposure is limited to organizations running Tap&Sign, especially web-accessible deployments where high-privilege users can submit content rendered into pages. The sources do not define specific modules, deployment models, or CPEs.
Exploitation context
The provided record does not show CISA KEV listing or cited evidence of active exploitation. The CVSS vector indicates exploitation requires high privileges but no user interaction, reducing broad opportunistic risk while preserving insider or compromised-admin risk.
Researcher notes
The source bundle is sparse: affected version formatting is unclear, CPEs are absent, one government reference is marked broken, and no remediation is specified. Do not assume exploitability beyond the CVSS vector and XSS classification without vendor or advisory detail.
Mitigation direction
Check Tapandsign and government advisories for vendor guidance or fixed versions.
Restrict Tap&Sign administrative access to trusted networks and users.
Review input handling and output encoding in configurable content areas.
Monitor for vendor updates because no patch is named in the sources.
Validation and detection
Inventory Tap&Sign deployments and record exact product versions.
Confirm whether any deployment is at or below the affected version marker.
Review privileged user workflows that render submitted content into web pages.
Check application logs for unusual script-like input from privileged accounts.

Client-side and session-facing weaknesses should be reviewed alongside initial-access and user-execution behaviors. Open the exact CWE lookup page first, then review the ATT&CK searches from that MITRE weakness context. This is a Glexia lookup hint, not an official ATT&CK mapping.
These fields come from the CVE record and ADP containers, not from Glexia's Take. They preserve time-varying source decisions such as CISA SSVC, KEV status, CVSS metrics, and provider references.
We collect every scored CVSS vector available in the official CNA and ADP containers. When more than one version is present, the table keeps the source vectors side by side instead of collapsing them into the highest score.
