Victim-browser script execution via corporate-group name injection
Published Oct 2, 2026 · Updated Oct 2, 2026
Cross-site scripting in Klosions TIC, S.L.U. Repasat allows remote authenticated users to execute script in a victim's browser. The corporate-group update endpoint accepts the nomGrupoEmpresarial parameter without sufficient neutralization for browser rendering; the public record does not identify the rendering code or whether the payload is stored. Exploitation requires an authenticated attacker and active victim interaction, and the script runs in the victim's browser rather than on the server.
