CVE-2022-2720Network attack vector

Sensitive data disclosure via incomplete substring masking

Published Oct 12, 2022 · Updated May 16, 2025

Information exposure in Octopus Server affected releases allows remote attackers to read partially masked sensitive values. The sensitive-value masking logic replaces a secret incorrectly when it is a substring of another sensitive value, leaving part of it visible. Network access is sufficient to obtain the exposed portion, with no reported ability to alter data or interrupt service.
