Summary

Penpot is an open-source design tool for design and code collaboration. Prior to 2.14.5, Penpot exposed teams_invitations.clj invitation tokens from create-team-invitations, embedded an existing profile id in auth.clj prepare-register-profile, and had auth.clj register-profile issue a session based on the invitation email match without password verification, allowing a registered user to take over any non-blocked profile. This issue is fixed in version 2.14.5.
