Excess account creation via invitation limit bypass
Published May 19, 2022 · Updated Aug 3, 2024
Access control failure in Octopus Server allows remote attackers with a valid invitation code to create excess user accounts. The invitation-code redemption path fails to enforce the code's configured maximum-use count, although Octopus Deploy has not disclosed the specific faulty function. Attackers must possess a valid invitation code, and the demonstrated consequence is limited to creating accounts beyond its intended user count.
