CVE-2025-0588

Name of the Vulnerable Software and Affected Versions: Octopus Server (affected versions not specified)

Description: In affected versions of Octopus Server, a user with sufficient access could set custom headers in all server responses. By submitting a specifically crafted referrer header, the user could ensure that all subsequent server responses would return 500 errors, rendering the site mostly unusable. The user could subsequently set and unset the referrer header to control the denial of service state with a valid CSRF token, whilst new CSRF tokens could not be generated.

Recommendations: At the moment, there is no information about a newer version that contains a fix for this vulnerability.
