The version of amazon-cloudwatch-agent installed on the remote host is prior to 1.300067.1-1. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2026-3389 advisory.

    Parsing arbitrary HTML can consume excessive CPU time, possibly leading to denial of service.
    (CVE-2026-25680)

    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.
    (CVE-2026-39829)

    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-2026-39830)

    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-2026-39831)

    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-2026-39833)

    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-2026-42508)

    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-2026-46595)

Tenable has extracted the preceding description block directly from the tested product security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2026-1788 advisory.

    Parsing arbitrary HTML can consume excessive CPU time, possibly leading to denial of service.
    (CVE-2026-25680)

    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-2026-25681)

    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-2026-27136)

    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-2026-39821)

    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-2026-39827)

    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-2026-39828)

    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.

    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-2026-39831)

    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-2026-39832)

    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-2026-39833)

    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-2026-39834)

    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-2026-39835)

    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)

    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-2026-42508)

    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-2026-46595)

    An incorrectly placed cast from bytes to int allowed for server-side panic in the AES-GCM packet decoder     for well-crafted inputs. (CVE-2026-46597)

    For certain crafted inputs, a 'ed25519.PrivateKey' was created by casting malformed wire bytes, leading to     a panic when used. (CVE-2026-46598)
