CVE-2022-31022

Bleve is a text indexing library for go. Bleve includes HTTP utilities
under bleve/http package, that are used by its sample application. These
HTTP methods pave way for exploitation of a node’s filesystem where the
bleve index resides, if the user has used bleve’s own HTTP (bleve/http)
handlers for exposing the access to the indexes. For instance, the
CreateIndexHandler (http/index_create.go) and DeleteIndexHandler
(http/index_delete.go) enable an attacker to create a bleve index
(directory structure) anywhere where the user running the server has the
write permissions and to delete recursively any directory owned by the same
user account. Users who have used the bleve/http package for exposing
access to bleve index without the explicit handling for the Role Based
Access Controls(RBAC) of the index assets would be impacted by this issue.
There is no patch for this issue because the http package is purely
intended to be used for demonstration purposes. Bleve was never designed
handle the RBACs, nor it was ever advertised to be used in that way. The
collaborators of this project have decided to stay away from adding any
authentication or authorization to bleve project at the moment. The
bleve/http package is mainly for demonstration purposes and it lacks
exhaustive validation of the user inputs as well as any authentication and
authorization measures. It is recommended to not use bleve/http in
production use cases.
