postgres-protocol: Panic decoding a malformed `hstore` value allows denial of service

A malicious or compromised server can return a binary hstore value with an invalid internal length field, causing the client to panic while decoding it. Applications that connect only to a trusted database are not exposed; the risk applies to clients that may connect to untrusted or user-supplied...

GHSA-5X78-73V4-XG6W postgres-protocol: Unbounded SCRAM iteration count allows a malicious server to cause CPU-exhaustion denial of service

A malicious, compromised, or man-in-the-middle server can supply an arbitrarily large SCRAM-SHA-256 PBKDF2 iteration count during authentication. The client runs it inline with no upper bound, pinning a tokio worker thread for minutes per connection, possibly stalling the whole async runtime...

CVE-2026-45678

OpenTelemetry eBPF Instrumentation provides eBPF instrumentation based on the OpenTelemetry standard. Prior to version 0.9.0, the Postgres protocol parser assumes BIND message payloads contain a valid NUL-terminated portal name. A crafted empty or unterminated payload can make OBI slice beyond th...

OpenTelemetry eBPF Instrumentation: Postgres BIND parsing can panic on malformed payloads

Summary The Postgres protocol parser assumes BIND message payloads contain a valid NUL-terminated portal name. A crafted empty or unterminated payload can make OBI slice beyond the end of the captured buffer and panic. Details The vulnerable logic is in pkg/ebpf/common/sqldetectpostgres.go. In th...

CVE-2026-26932 Improper Validation of Array Index in Packetbeat Leading to Denial of Service

Improper Validation of Array Index CWE-129 in the PostgreSQL protocol parser in Packetbeat can lead Denial of Service via Input Data Manipulation CAPEC-153. An attacker can send a specially crafted packet causing a Go runtime panic that terminates the Packetbeat process. This vulnerability requir...

CVE-2024-32655

Npgsql is the .NET data provider for PostgreSQL. The WriteBind method in src/Npgsql/Internal/NpgsqlConnector.FrontendMessages.cs uses int variables to store the message length and the sum of parameter lengths. Both variables overflow when the sum of parameter lengths becomes too large. This cause...
