# CVE-2026-19877: Brute-forceable image-share link password in INFINITT ULite

Status: published. Published: 2026-11-06. Updated: 2026-11-06.

INFINITT ULite 5.0.2.1_BN48_20260528 and earlier protects image-share links with a low-entropy password and does not restrict repeated password attempts, allowing an unauthenticated remote attacker to brute-force the password within the link validity window and gain unauthorized access to shared medical images. Fixed in ULite 5.0.2.1 BN50.

## Remediation

- fix: Upgrade to INFINITT ULite 5.0.2.1 BN50 or later. Generate share passwords with at least 128 bits of entropy, and rate-limit / lock out repeated attempts (count failures against the per-link quota). (source: CNA: NCSC.ch)
