| CVE | Sev | CVSS | KEV | Affected versions | Fixed in | Published | Description |
|---|---|---|---|---|---|---|---|
| CVE-2026-78662 | Hig | 7.5 | < 0 | 0 | Sep 2, 2026 | Previously, a channel registered in the mux's chanList is not usable until it is established. A malicious peer was able flood the channel's incomingRequests, deadlocking the entire connection. Now, we add an atomic established state, set when a channel becomes usable. Until such | |
| CVE-2026-56855 | Hig | 7.5 | < 0 | 0 | Sep 2, 2026 | Previously, after a channel has been established, a malicious peer could send crafted messages that would deadlock the entire connection. Now, we handle all RFC 4254 channel messages; global requests are handled explicitly. Then, treat all other messages as a protocol error and t | |
| CVE-2026-84304 | Hig | — | < 0.4.1-r24 | 0.4.1-r24 | Sep 1, 2026 | gRPC-Go is the Go language implementation of gRPC. Prior to 1.83.1, internal/transport/transport.go stores each fragmented HTTP/2 DATA frame as a separate recvMsg in recvBuffer, so millions of one-byte frames can consume disproportionate heap memory even when payload bytes remain | |
| CVE-2026-56854 | Hig | 7.5 | < 0 | 0 | Aug 28, 2026 | The source-address critical option in the Permissions returned by an authentication callback was only enforced for the PublicKeyCallback and VerifiedPublicKeyCallback paths, extending the fix for CVE-2026-46595. Permissions returned by the PasswordCallback, KeyboardInteractiveCal | |
| CVE-2026-56862 | Hig | 7.5 | < 0.4.1-r20 | 0.4.1-r20 | Aug 13, 2026 | Handshake messages, such as KeyUpdate, are always considered as state-advancing, regardless of whether a handshake has been completed or not. As a result, a malicious client can keep sending KeyUpdate messages to force the server to keep performing key derivation operations indef | |
| CVE-2026-56860 | Med | 5.9 | < 0.4.1-r20 | 0.4.1-r20 | Aug 13, 2026 | Previously, resolving relative paths containing parent directory ('..') segments performed string conversions and buffer rewrites on each step, resulting in quadratic time complexity and high memory allocation overhead. Now, path resolution operates on a byte buffer using index-b | |
| CVE-2026-56859 | Hig | 7.5 | < 0 | 0 | Aug 13, 2026 | Previously, DecodeElement would reset the depth counter causing it to never fire; this could lead to stack exhaustion. | |
| CVE-2026-56858 | Med | 6.1 | < 0.4.1-r20 | 0.4.1-r20 | Aug 13, 2026 | Previously, pathological inputs could close an unescaped '/' early, allowing for attack-controlled data to inject arbitrary content, potentially leading to XSS. | |
| CVE-2026-56853 | Hig | 7.5 | < 0 | 0 | Aug 13, 2026 | When a server is configured to support unencrypted HTTP/2, it reads a few bytes from each new connection to see if they contain the HTTP/2 client preface. ReadHeaderTimeout is unexpectedly not being applied when doing this. | |
| CVE-2026-33818 | Hig | 7.5 | < 0.4.1-r20 | 0.4.1-r20 | Aug 13, 2026 | Enforce a recursion limit in Unmarshal to prevent stack exhaustion when parsing deeply-nested, recursive structures. | |
| CVE-2026-56852 | Hig | 7.5 | < 0 | 0 | Jul 21, 2026 | A norm.Iter can enter an infinite loop when handling input containing invalid UTF-8 bytes. | |
| CVE-2026-46600 | Hig | 7.5 | < 0 | 0 | Jul 21, 2026 | Parsing an invalid SVCB or HTTPS RR can panic when the size of a parameter value overflows the message buffer. | |
| CVE-2026-41178 | Med | 5.3 | < 0.4.1-r19 | 0.4.1-r19 | Jun 4, 2026 | OpenTelemetry-Go is the Go implementation of OpenTelemetry. Versions 1.41.0 and 1.43.0 removed raw-length rejection and it causes `Parse` to process arbitrarily large/invalid baggage headers and log errors, enabling DoS via oversized inputs. Versions 1.42.0 and 1.44.0 fix the iss | |
| CVE-2026-39821 | Cri | 9.6 | < 0.4.1-r20 | 0.4.1-r20 | May 22, 2026 | The ToASCII and ToUnicode functions incorrectly accept Punycode-encoded labels that decode to an ASCII-only label. For example, ToUnicode("xn--example-.com") incorrectly returns the name "example.com" rather than an error. This behavior can lead to privilege escalation in program | |
| CVE-2026-46598 | Med | 5.3 | < 0 | 0 | May 22, 2026 | For certain crafted inputs, a 'ed25519.PrivateKey' was created by casting malformed wire bytes, leading to a panic when used. | |
| CVE-2026-46597 | Hig | 7.5 | < 0 | 0 | May 22, 2026 | An incorrectly placed cast from bytes to int allowed for server-side panic in the AES-GCM packet decoder for well-crafted inputs. | |
| CVE-2026-46595 | Cri | 10.0 | < 0 | 0 | May 22, 2026 | Previously, CVE-2024-45337 fixed an authorization bypass for misused ssh server configurations; if any other type of callback is passed other than public key, then the source-address validation would be skipped. | |
| CVE-2026-39835 | Med | 5.3 | < 0 | 0 | May 22, 2026 | SSH servers which use CertChecker as a public key callback without setting IsUserAuthority or IsHostAuthority could be caused to panic by a client presenting a certificate. CertChecker now returns an error instead of panicking when these callbacks are nil. | |
| CVE-2026-39834 | Cri | 9.1 | < 0 | 0 | May 22, 2026 | When writing data larger than 4GB in a single Write call on an SSH channel, an integer overflow in the internal payload size calculation caused the write loop to spin indefinitely, sending empty packets without making progress. The size comparison now uses int64 to prevent trunca | |
| CVE-2026-39833 | Cri | 9.1 | < 0 | 0 | May 22, 2026 | The in-memory keyring returned by NewKeyring() silently accepted keys with the ConfirmBeforeUse constraint but never enforced it. The key would sign without any confirmation prompt, with no indication to the caller that the constraint was not in effect. NewKeyring() now returns a |
