Stored XSS in IceHrm 30.0.0.OS allows remote authenticated users to execute JavaScript in another user's browser via a malicious file upload. The Training Sessions and Travel Requests upload functions accept attacker-controlled files that are later rendered without neutralizing executable script content. An authenticated account must upload the file and a victim must view the stored content; execution is confined to the victim's IceHrm browser context.
