What it is

Penpot is an open-source design and prototyping platform. Prior to 2.18.0, the delete-share-link RPC retrieves a caller-selected share-link ID and verifies only that the caller can edit the parent file. It does not verify that the caller created the share link or has owner or administrator authority, allowing any file editor who knows a share-link UUID to delete links created by other users and revoke external reviewers' access. This issue is fixed in version 2.18.0.
