CVE-2026-27968Network attack vector

Private repository access via expired deploy tokens

Published Feb 26, 2026 · Updated Feb 26, 2026

Improper authentication in Packistry before 0.13.0 allows remote authenticated users to read private repository content with expired tokens. RepositoryAwareController::authorize() checks token presence and ability but fails to call isExpired() before authorizing repository requests. Possession of an expired deploy token with the required repository-read ability is necessary, and exposure is limited to content that token could access.
