High CVSS 7.1

CVE-2026-14871

NVD analysis in progress

osTicket versions v1.18.3 and v1.17.7 contain a Broken Object Level Authorization (BOLA) leading to Insecure Direct Object Reference (IDOR) in the AJAX ticket-management subsystem.

What this means

Exposure: Exploitable remotely over the network, with an ordinary user account and with no action from the victim.
Impact: An attacker can read sensitive data.
Weakness: An authorisation check exists but its logic is wrong.
Likelihood: Its EPSS score stays low: nothing points to imminent exploitation, which is no reason to leave it unpatched.

What to doFold into the next patch cycle.

Read automatically from the CVSS vector, the weakness type (CWE) and the EPSS score. The technical description above remains the one published by NIST.
