What it is

we-mp-rss through 1.5.3 contains a missing authorization vulnerability in the /api/v1/wx/tools/export/download endpoint that allows unauthenticated attackers to download export archives because its authentication dependency is commented out. Attackers can supply an mp_id and guessable timestamp-based export filename to retrieve archives under data/docs, and set delete_after_download=true to delete them.
