MEDIUM 5.3
Description
User enumeration vulnerability in /pwreset.php in osTicket v1.18.2 allows remote attackers to enumerate valid usernames registered in the platform.
Analysis
User enumeration in osTicket v1.18.2's password reset endpoint (/pwreset.php) enables remote attackers to discover valid usernames through response analysis, facilitating targeted account compromise attempts. No CVSS score, CISA KEV status, or confirmed patch information is available; exploitation likelihood depends on whether timing or behavioral differences between valid and invalid usernames can be reliably detected without authentication.
