CVE-2026-38444

osTicket v1.18.3 is vulnerable to Stored Cross-Site Scripting XSS via the email From-header display name. The value is extracted without sanitization in include/class.mailparse.php and stored raw in the poster field of ostthreadentry. When an unauthenticated attacker sends a reply email to an...

CVE-2026-38447

osTicket 1.18.3 generates API keys using a predictable construction based on MD5 hashing. The use of MD5, combined with predictable inputs such as the current timestamp and client IP address, significantly reduces entropy. An attacker can approximate the key generation time and brute-force the ke...
