  1. CVE-2026-65423 8.8 Élevée

    o6 Automation open62541

    An integer overflow in the UA_Variant arrayDimensions product computation in open62541 may allow a remote attacker to trigger an out-of-bounds write.

  2. CVE-2026-63362 5.9 Moyenne

    o6 Automation open62541

    An unsigned integer underflow in the PubSub signature verification path in open62541 may allow a remote attacker to cause a denial of service via a crafted UDP packet.

  3. CVE-2026-63035 8.1 Élevée

    o6 Automation open62541

    A heap use-after-free vulnerability in the TransferSubscriptions service in open62541 may allow an authenticated attacker to cause a denial of service or potentially execute arbitrary code.

  4. CVE-2026-63559 7.5 Élevée

    o6 Automation open62541

    An integer overflow in the UA_Variant arrayDimensions product computation in open62541 may allow a remote attacker to read out-of-bounds heap memory, potentially disclosing sensitive information.

  5. CVE-2026-11946 7.5 Élevée

    open62541 project / o6 Automation GmbH open62541

    An unauthenticated remote attacker can exhaust server memory via the GetEndpoints Discovery Service in open62541. The endpointUrl field of GetEndpointsRequest is not validated for length. An attacker can declare an arbitrarily large string (up to ~4.09 GB via the UInt32 length field) delivered across intermediate chunks without ever sending the final chunk. The server buffers all chunks in RAM indefinitely until the SecureChannel times out. The attack is pre-session and bypasses all encryption configurations. The issue affects open62541: from 1.4.0 through 1.4.16, from 1.5.0 through 1.5.4, master.

  6. CVE-2026-33592 7.5 Élevée

    open62541 project / o6 Automation GmbH open62541

    An unauthenticated remote attacker can exhaust server memory via the FindServers Discovery Service in open62541. The serverUris field of FindServersRequest is not validated for length or array size. An attacker can declare an arbitrarily large string (up to ~3.9 GB) delivered across intermediate chunks without ever sending the final chunk. The server buffers all chunks in RAM indefinitely until the SecureChannel times out. The attack is pre-session and bypasses all encryption configuration. The issue affects open62541: from 1.4.0 through 1.4.16, from 1.5.0 through 1.5.4, master.
