CVE-2026-11993

Mattermost versions 11.9.x ≤ 11.9.0 , 11.8.x ≤ 11.8.4 , 11.7.x ≤ 11.7.7 , and 10.11.x ≤ 10.11.22 are affected by a resource-exhaustion flaw in the file content indexing subsystem. The root cause is a failure to properly enforce the limit of concurrent files being processed and to handle failed fi...

CVE-2026-11993 Fix authenticated members disabling file content indexing server-wide via extraction pool exhaustion

Mattermost versions 11.9.x = 11.9.0, 11.8.x = 11.8.4, 11.7.x = 11.7.7, 10.11.x = 10.11.22 fail to properly enforce the limit of concurrent files being processed and handled failed files, which allows a user with permission to upload files to spawn more goroutines than intended and block the...

filebrowser through 2.63.23 fails to validate named pipes in directory archive and public download handlers, allowing attackers to trigger blocking open syscalls. Authenticated users or anonymous visitors with public share links can repeatedly request archives containing named pipes to pin server...

CVE-2026-82235

filebrowser through 2.63.23 fails to validate named pipes in its directory archive and public download handlers. This causes blocking open syscalls that pin server goroutines and exhaust connection resources, resulting in a denial of service . Both authenticated users and anonymous visitors with ...

CVE-2026-73500

A flaw was found in etcd, a distributed key-value store. A remote attacker can exploit this by opening numerous TCP connections to an etcd TLS listener without completing the TLS handshake. This action causes the tlsListener.acceptLoop to spawn an unbounded number of goroutines, which consume...

GO-2026-6107 Unbounded TLS handshake goroutines in go.etcd.io/etcd/client/pkg/v3

In go.etcd.io/etcd/client/pkg/v3 before 3.5.33, 3.6.14, and 3.7.1, TLS handshakes on listeners created by NewTLSListener do not enforce a handshake deadline. An unauthenticated network attacker who connects to an etcd TLS listener without sending a ClientHello causes a goroutine and a tracking ma...

AZL-95913 CVE-2026-73500 affecting package flannel for versions less than 0.24.2-31

etcd is a distributed key-value store for the data of a distributed system. Prior to versions 3.5.33, 3.6.14, and 3.7.1, a network attacker who can reach an etcd TLS listener can open many TCP connections and never send a ClientHello. In client/pkg/transport/listenertls.go, each connection handle...

The version of Grafana Labs installed on the remote host is affected by a denial of service vulnerability as referenced in the CVE-2026-21720 advisory. - Every uncached /avatar/:hash request spawns a goroutine that refreshes the Gravatar image. If the refresh sits in the 10-slot worker queue long...

SUSE CVE-2026-21720

Every uncached /avatar/:hash request spawns a goroutine that refreshes the Gravatar image. If the refresh sits in the 10-slot worker queue longer than three seconds, the handler times out and stops listening for the result, so that goroutine blocks forever trying to send on an unbuffered channel...

AZL-98988 CVE-2023-39325 affecting package golang 1.27.1-1

A malicious HTTP/2 client which rapidly creates requests and immediately resets them can cause excessive server resource consumption. While the total number of requests is bounded by the http2.Server.MaxConcurrentStreams setting, resetting an in-progress request allows the attacker to create a ne...
