Executive Summary

CVE-2026-92213 is a CSS injection vulnerability in the a2ui project up to version 0.10.6. It occurs in the Angular Renderer where the primaryColor theme value is passed directly to CSS without validation. An attacker can manipulate this value to inject malicious CSS, such as URLs, leading to potential data exfiltration or UI spoofing.

Detection Guidance

Detecting this vulnerability requires checking if the a2ui project version is vulnerable (up to 0.10.6) and inspecting for CSS injection attempts in theme values. Review server logs for suspicious CSS values like URLs in primaryColor fields. Use commands like 'npm list a2ui' to check installed versions and 'grep -r "primaryColor" /path/to/project' to search for theme usage.

Impact Analysis

This vulnerability allows remote attackers to inject CSS values like URLs, which can trigger cross-origin requests from the host. This may expose sensitive information such as IP addresses or User-Agent details. It can also enable UI spoofing by overlaying attacker-chosen content on legitimate UI elements.

Mitigation Strategies

Immediately update to the patched version of a2ui (commit fb8e85aec78d04e81feb9992a57638ca1ec4dc1b). Validate all theme inputs to ensure primaryColor uses only hex codes, named colors, or functional notations. Replace background properties with background-color in Angular components to block URL-based CSS injections.
