klever-go: Unbounded goroutine spawn on direct-message ingress enables peer-driven DoS
Summary networkMessenger.directMessageHandler in network/p2p/libp2p/netMessenger.go spawns a fresh goroutine for every incoming direct message before the antiflood layer makes an admission decision. There is no semaphore, throttler, or bound on concurrent in-flight spawns. A single connected libp...

CVE-2026-42594 Gotenberg: Unauthenticated denial of service via echo.Context pool reuse in webhook async goroutine
Gotenberg is a Docker-powered stateless API for PDF files. Prior to 8.32.0, the webhook middleware spawns a goroutine that holds a reference to the request's echo.Context after the synchronous handler returns ErrAsyncProcess and Echo recycles the context back to its sync.Pool. When a concurrent...
CVE-2026-42594
Gotenberg CVE-2026-42594 describes an unauthenticated denial of service caused by reuse of echo.Context in the webhook async flow. Prior to 8.32.0, a goroutine holds a reference to the request context after ErrAsyncProcess, and Echo recycles the context to a pool. If a concurrent request reuses t...
Memory Forensics Techniques for Automated Detection and Analysis of Go Malware
The Go programming language has become increasingly popular among malware developers due to its ability to produce statically linked, cross-platform executables that challenge traditional analysis techniques. These binaries embed a substantial runtime and compiler-generated metadata and are...
GHSA-2G4X-FQ3J-CGQ4 Dalfox has an Unauthenticated Remote DoS via Closed-Channel Write in `ParameterAnalysis` (server mode)
Summary ParameterAnalysis in pkg/scanning/parameterAnalysis.go runs two sequential worker stages that both write to the same results channel. The channel is correctly closed after the first stage completes closeresults at line 438, but the second stage — which processes POST-body parameters dp — ...
