etcd is a distributed key-value store for the data of a distributed system. Prior to versions 3.4.42, 3.5.28, and 3.6.9, unauthorized users may bypass authentication or authorization checks and call certain etcd functions in clusters that expose the gRPC API to untrusted or partially trusted...

GHSA-8G29-8XWR-QMHR @grackle-ai/server JSON.parse lacks try-catch logic in its gRPC Service AdapterConfig Handling

Impact JSON.parseenv.adapterConfig is called without error handling in three locations within the gRPC service. While the data originates from the server's own SQLite database and should always be valid JSON, database corruption, migration errors, or unexpected state could cause an unhandled...

CVE-2026-33186

A flaw was found in gRPC-Go, the Go language implementation of gRPC. This vulnerability, an authorization bypass, is caused by improper input validation of the HTTP/2 :path pseudo-header. A remote attacker can exploit this by sending raw HTTP/2 frames with a malformed :path that omits the mandato...

AWS VDP: V2Plugin.Decrypt panics on empty ciphertext (Remote DoS)

A vulnerability was discovered in the "aws-encryption-provider" component where the "V2Plugin.Decrypt" function accessed the ciphertext slice without checking if it was empty, leading to a panic and crashing the entire gRPC server process...
