CVE-2026-105948 · Severity: info · Published 2026-11-11

Octopus Server is a continuous deployment and release management platform used for automating software releases. In affected versions with LDAP authentication enabled, a user can edit their own login identities due to incorrect permission validation, allowing them to escalate their privileges up to system administrator level. This could allow an attacker with any user account to gain complete control of the deployment system.
