Registry write access via partial DeployKey matches
Published Dec 31, 2024 · Updated Dec 31, 2024
Authorization bypass in PacoVK Tapir 0.9.0 through 0.9.1 allows remote attackers to gain registry write access with a guessed DeployKey. The getDeployKeyByValue methods for DynamoDB, Cosmos DB, and Elasticsearch accept the first search result without checking that its key exactly equals the supplied value. A guessed substring matched to a scoped DeployKey is therefore accepted as that key, granting its configured write scope.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
