Authenticated cross-site scripting via undisclosed input handling

Published Dec 10, 2025 · Updated Dec 10, 2025

Cross-site scripting in TAC A.S. GOLDENHORN before 4.25.1121.1 allows remote authenticated users to read limited information. The CNA and vendor-linked advisory do not identify the affected endpoint, input field, or missing output-neutralization operation. Exploitation requires low-privileged authentication and a victim to interact with crafted content; the reported consequence is limited to confidentiality.
