  1. CVE-2026-14940 5.3 Moyenne

    Red Hat Directory Server 11 · Red Hat Directory Server 12 · Red Hat Directory Server 13 · Red Hat Enterprise Linux 10

    A heap-buffer-overflow flaw was found in 389 Directory Server (389-ds-base). When normalizing a Distinguished Name (DN) that contains a legacy-quoted value encoding a multivalued nested Relative Distinguished Name (RDN), the server can write past the end of a heap allocation while sorting RDN attribute-value pairs. An unauthenticated remote attacker can trigger this condition by sending an LDAP operation whose DN reaches the DN normalization routine, such as a search with a crafted base DN. This can corrupt heap memory and may cause denial of service.

  2. CVE-2026-14969 4.4 Moyenne

    Red Hat Directory Server 11 · Red Hat Directory Server 12 · Red Hat Directory Server 13 · Red Hat Enterprise Linux 10

    A flaw was found in 389-ds-base where the LDBM backend attribute encryption uses a hardcoded static initialization vector for AES-CBC and 3DES-CBC operations, allowing an attacker with privileged filesystem access to detect plaintext equality across encrypted entries by comparing ciphertext blocks.

  3. CVE-2026-15041 3.7 Faible

    Red Hat Directory Server 11 · Red Hat Directory Server 12 · Red Hat Directory Server 13 · Red Hat Enterprise Linux 10

    A flaw was found in 389 Directory Server. The PBKDF2-SHA256 password verification function uses standard memcmp() for comparing password hashes instead of a constant-time comparison function. A remote attacker could potentially use timing measurements of LDAP bind attempts to infer partial hash information, though practical exploitation is extremely difficult due to PBKDF2 computational overhead.

  4. CVE-2026-58207 6.5 Moyenne

    nats-io nats-server · Linuxfoundation nats-server

    NATS Server is a high-performance server for NATS.io, the cloud and edge native messaging system. Prior to 2.14.3 and 2.12.12, a client able to send account-scoped connection monitoring requests could crash the server by supplying Connz pagination Offset and Limit values that overflowed internal arithmetic before the response window was safely bounded. This issue is fixed in versions 2.14.3 and 2.12.12.

  5. CVE-2026-58208 7.5 Élevée

    nats-io nats-server · Linuxfoundation nats-server

    NATS Server is a high-performance server for NATS.io, the cloud and edge native messaging system. Prior to 2.14.3 and 2.12.12, a WebSocket listener could route requests for the MQTT-over-WebSocket path into MQTT handling even when MQTT was not configured, allowing an unauthenticated client with access to the WebSocket listener to reach uninitialized MQTT state and crash the server process. This issue is fixed in versions 2.14.3 and 2.12.12.

  6. CVE-2026-58211 5.4 Moyenne

    nats-io nats-server · Linuxfoundation nats-server

    NATS Server is a high-performance server for NATS.io, the cloud and edge native messaging system. Prior to 2.14.3 and 2.12.12, a client could be registered as the configured no_auth_user through a parser path used when the first client operation was not CONNECT, bypassing user-level connection restrictions such as allowed_connection_types or proxy_required that normal authentication would apply. This issue is fixed in versions 2.14.3 and 2.12.12.

  7. CVE-2026-13020 9.8 Critique

    Esri Portal for ArcGIS

    A Weak Password Recovery Mechanism for Forgotten Password exists in Esri Portal for ArcGIS versions 12.1 and earlier on Windows, Linux and Kubernetes. A remote, unauthorized attacker may assume ownership of a user’s account by manipulating this mechanism. ArcGIS Administrators should configure an email server with ArcGIS Enterprise to facilitate user self-service password recovery. The ability for an administrator to reset a user’s password remains unchanged.
