CVE-2026-44733Network attack vector

Persistent account access via unchecked password change

Published Jun 26, 2026 · Updated Jun 26, 2026

Logic error in OpenProject before 17.3.2 allows remote attackers to change an account password through the self-profile API. The self-profile password-change handler fails to enforce password validation before accepting a replacement credential. Exploitation requires prior takeover of an active account session; the accepted change turns temporary session access into persistent account access.
