Prior to 3.41.3, POST /api/attachments/:datasourceId/url in packages/server/src/api/routes/static.ts and packages/server/src/api/controllers/static/index.ts allows an authenticated published-app user with the BASIC role to supply attacker-controlled bucket and key values and obtain signedUrl and publicUrl values backed by stored S3 datasource credentials. This issue is fixed in version 3.41.3.
