CVE-2026-42502 1 Golang 1 Net 2026-05-29 6.1 Medium
Parsing arbitrary HTML which is then rendered using Render can result in an unexpected HTML tree. This can be leveraged to execute XSS attacks in applications that attempt to sanitize input HTML before rendering.
CVE-2026-42506 1 Golang 1 Net 2026-05-29 6.1 Medium

CVE-2026-27136 1 Golang 1 Net 2026-05-29 6.1 Medium
Parsing arbitrary HTML which is then rendered using Render can result in an unexpected HTML tree. This can be leveraged to execute XSS attacks in applications that attempt to sanitize input HTML before rendering.
CVE-2026-25680 1 Golang 1 Net 2026-05-29 6.5 Medium
Parsing arbitrary HTML can consume excessive CPU time, possibly leading to denial of service.

CVE-2026-39821 1 Golang 1 Net 2026-05-29 9.6 Critical
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 programs using the idna package. For example, a program which performs privilege checks on the ASCII hostname may reject "example.com" but permit "xn--example-.com". If that program subsequently converts the ASCII hostname to Unicode, it will inadvertently permits access to the Unicode name "example.com".
CVE-2026-39834 1 Golang 2 Crypto, Ssh 2026-05-28 9.1 Critical
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 truncation.
CVE-2026-39832 1 Golang 2 Crypto, Ssh 2026-05-28 9.1 Critical
When adding a key to a remote agent constraint extensions such as restrict-destination-v00@openssh.com were not serialized in the request. Destination restrictions were silently stripped when forwarding keys, allowing unrestricted use of the key on the remote host. The client now serializes all constraint extensions. Additionally, the in-memory keyring returned by NewKeyring() now rejects keys with unsupported constraint extensions instead of silently ignoring them.
CVE-2026-39835 1 Golang 2 Crypto, Ssh 2026-05-28 5.3 Medium
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-2026-39833 1 Golang 2 Crypto, Ssh 2026-05-28 9.1 Critical
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 an error when unsupported constraints are requested.
CVE-2026-42508 1 Golang 2 Crypto, Ssh 2026-05-28 9.1 Critical
Previously, a revoked 'SignatureKey' belonging to a CA was not correctly checked for revocation. Now, both the 'key' and 'key.SignatureKey' are checked for @revoked.
CVE-2026-46595 1 Golang 2 Crypto, Ssh 2026-05-28 10 Critical
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-2026-46597 1 Golang 2 Crypto, Ssh 2026-05-28 7.5 High
An incorrectly placed cast from bytes to int allowed for server-side panic in the AES-GCM packet decoder for well-crafted inputs.
CVE-2026-46598 1 Golang 2 Crypto, Ssh 2026-05-28 5.3 Medium
For certain crafted inputs, a 'ed25519.PrivateKey' was created by casting malformed wire bytes, leading to a panic when used.
CVE-2026-39824 1 Golang 1 Sys 2026-05-27 3.3 Low
NewNTUnicodeString does not check for string length overflow. When provided with a string that overflows the maximum size of a NTUnicodeString (a 16-bit number of bytes), it returns a truncated string rather than an error.
CVE-2026-39827 1 Golang 2 Crypto, Ssh 2026-05-26 6.5 Medium
An authenticated SSH client that repeatedly opened channels which were rejected by the server caused unbounded memory growth, eventually crashing the server process and affecting all connected users. Rejected channels are now properly removed from the connection's internal state and released for garbage collection.
CVE-2026-39831 1 Golang 1 Ssh 2026-05-22 9.1 Critical
The Verify() method for FIDO/U2F security key types (sk-ecdsa-sha2-nistp256@openssh.com, sk-ssh-ed25519@openssh.com) did not check the User Presence flag. Signatures generated without physical touch were accepted, allowing unattended use of a hardware security key. To restore the previous behavior, return a "no-touch-required" extension in Permissions.Extensions from PublicKeyCallback.
CVE-2026-39828 1 Golang 1 Ssh 2026-05-22 6.3 Medium
When an SSH server authentication callback returned PartialSuccessError with non-nil Permissions, those permissions were silently discarded, potentially dropping certificate restrictions such as force-command after a second factor succeeded. Returning non-nil Permissions with PartialSuccessError now results in a connection error.
CVE-2026-39830 1 Golang 1 Ssh 2026-05-22 9.1 Critical
A malicious SSH peer could send unsolicited global request responses to fill an internal buffer, blocking the connection's read loop. The blocked goroutine could not be released by calling Close(), resulting in a resource leak per connection. Unsolicited global responses are now discarded.
CVE-2026-39829 1 Golang 1 Ssh 2026-05-22 7.5 High
The RSA and DSA public key parsers did not enforce size limits on key parameters. A crafted public key with an excessively large modulus or DSA parameter could cause several minutes of CPU consumption during signature verification. This could be triggered by unauthenticated clients during public key authentication. RSA moduli are now limited to 8192 bits, and DSA parameters are validated per FIPS 186-2.
