CVE-2026-3236
In affected versions of Octopus Server it was possible to create a new API key from an existing access token resulting in the new API key having a lifetime exceeding the original API key used to mint the access token.
Does this matter?
Lower severity and a low EPSS score (0.16%). Track it; it rarely justifies an emergency change on its own.
