Description
iFlytek SkillHub through 0.2.22 contains a missing authorization vulnerability that allows any authenticated user to permanently delete other users' skills via DELETE /api/cli/v1/skills/{namespace}/{slug}. Attackers can locate targets through the anonymous search endpoint and trigger deletion without ownership checks, purging all versions, files, reviews, ratings and metadata.
