Recommendation: Plan a near-term fix — a public PoC already exists.

osTicket versions from 1.10 up to 1.17.7 and from 1.18.0 up to 1.18.3 are vulnerable to a stored XSS due to a vulnerable Bootstrap Tooltip component and insufficient HTML sanitization, allowing remote attackers to execute arbitrary JavaScript in Agent or Admin sessions.
