CriticalCVE-2026-49441wazuhWazuh : peer-controlled metadata key in process_files_from_worker non-merged branch allows arbitrary file write under WAZUH_PATH on Wazuh managerWazuh is a free and open source platform used for threat prevention, detection, and response. From 4.3.0 until 4.14.6 and 5.0.0-beta3, the non-merged branch of process_files_from_worker() in framework/wazuh/core/cluster/master.py trusts a peer-controlled file_path key from files_metadata.json. The destination is joined to WAZUH_PATH without proving that it remains inside the directory selected by cluster_item_key. A cluster peer holding the shared Fernet key can upload a crafted extra-valid archive and overwrite security-sensitive files such as /var/ossec/etc/ossec.conf. Replacing ossec.conf can configure root-executed commands and lead to code execution after a service reload. This issue is fixed in versions 4.14.6 and 5.0.0-beta3.EPSS0.77%MediumCVE-2026-49392wazuhWazuh: Local SQL injection in FIM db due to path lookup interpolation in wazuh-syscheckdWazuh is a free and open source platform used for threat prevention, detection, and response. From 4.6.0 until 4.14.6 and 5.0.0-beta3, DB::getFile() and DB::searchFile() in src/syscheckd/src/db/src/file.cpp concatenate a monitored file path into SQLite row filters. On non-Windows systems, FIMDBCreator::encodeString() does not escape the value. A local user who can create a filename in a File Integrity Monitoring directory can inject a UNION SELECT expression when wazuh-syscheckd processes or deletes that path. The confirmed primitive manipulates SELECT result sets consumed by the FIM code; stacked statements and remote code execution were not demonstrated. This issue is fixed in versions 4.14.6 and 5.0.0-beta3.EPSS0.30%MediumCVE-2026-32984wazuhHeap buffer overflow in wazuh-authdWazuh authd contains a heap-buffer overflow vulnerability that allows attackers to cause memory corruption and malformed heap data by sending specially crafted input. Attackers can exploit this vulnerability to trigger a denial of service condition, resulting in low impact on the availability of the authentication daemon.EPSS0.38%HighCVE-2026-32983wazuh +1 moreSSL/TLS Renegotiation DoS in Wazuh Manager authd serviceWazuh Manager authd service in wazuh-manager packages through version 4.7.3 contains an improper restriction of client-initiated SSL/TLS renegotiation vulnerability that allows remote attackers to cause a denial of service by sending excessive renegotiation requests. Attackers can exploit the lack of renegotiation limits to consume CPU resources and render the authd service unavailable.EPSS0.54%CriticalCVE-2026-30893wazuhWazuh cluster sync path traversal in decompress_files() enables arbitrary file write and code execution from authenticated cluster peerWazuh is a free and open source platform used for threat prevention, detection, and response. From version 4.4.0 to before version 4.14.4, a path traversal vulnerability in Wazuh's cluster synchronization extraction routine allows an authenticated cluster peer to write arbitrary files outside the intended extraction directory on other cluster nodes. This can be escalated to code execution in the Wazuh service context by overwriting Python modules loaded by Wazuh components (proof of concept available as separate attachment). In deployments where the cluster daemon runs with elevated privileges, system-level compromise is possible. This issue has been patched in version 4.14.4.EPSS0.62%HighCVE-2026-34150wazuhWazuh: Heap buffer overflow in wazuh-analysisd via rootcheck event parsingWazuh is a free and open source platform used for threat prevention, detection, and response. In versions 1.0.0 and above, prior to 4.14.5, a heap buffer overflow in wazuh-analysisd allows an unauthenticated remote attacker to crash the Wazuh manager's analysis engine, causing complete loss of SIEM alert processing. The attack exploits the default configuration shipped in the official wazuh/wazuh-docker deployment with default configuration. An attacker can enroll with authd without a password to obtain a valid agent ID and encryption key, connect to remoted over the Wazuh agent protocol, and inject rootcheck events containing {key: value} patterns longer than 30 bytes that trigger a sprintf overflow of a 30-byte buffer in W_JSON_ParseRootcheck, corrupting the heap and crashing wazuh-analysisd so that all alert processing silently stops while the dashboard and API keep showing stale data.EPSS0.37%MediumCVE-2026-33754wazuhWazuh: Unauthenticated cluster packet length leads to uncontrolled memory allocation (remote DoS)Wazuh is a free and open source platform used for threat prevention, detection, and response. In versions 3.9.0 and above, prior to 4.14.5, a remote attacker can trigger memory exhaustion in the cluster protocol parser by sending a crafted message header with an arbitrarily large payload length. The length is trusted before authentication/decryption and used directly to allocate memory, allowing unauthenticated denial of service of the cluster service. This issue has been fixed in version 4.14.5.EPSS0.37%HighCVE-2026-33434wazuhWazuh: Rate Limit Bypass via /events EndpointWazuh is a free and open source platform used for threat prevention, detection, and response. In versions 4.6.0 and above, prior to 4.14.5, a logic error in CheckRateLimitsMiddleware.dispatch() causes the /events endpoint rate check to unconditionally overwrite the general rate limit result. When the global max_request_per_minute is exceeded, requests to /events still succeed if the events-specific counter (hardcoded 30/min) has not been reached. This allows event injection into analysisd beyond the admin-configured global rate limit. This issue has been fixed in version 4.14.5.EPSS0.40%HighCVE-2023-42463wazuhwazuh-logcollector integer underflow local privilege escalationWazuh is a free and open source platform used for threat prevention, detection, and response. This bug introduced a stack overflow hazard that could allow a local privilege escalation. This vulnerability was patched in version 4.5.3.EPSS0.24%HighCVE-2023-42455wazuh · wazuh-dashboard +1 moreWazuh vulnerable to user privilege escalationWazuh is a security detection, visibility, and compliance open source project. In versions 4.4.0 and 4.4.1, it is possible to get the Wazuh API administrator key used by the Dashboard using the browser development tools. This allows a logged user to the dashboard to become administrator of the API, even if their dashboard role is not. Version 4.4.2 contains a fix. There are no known workarounds.EPSS0.73%MediumCVE-2023-7340wazuhWazuh authd service (os_auth) Heap-based Buffer OverflowWazuh authd contains a heap-buffer overflow vulnerability that allows attackers to cause memory corruption and malformed heap data by sending specially crafted input. Attackers can exploit this vulnerability to trigger a denial of service condition, resulting in low availability impact to the authentication daemon.EPSS0.32%MediumCVE-2023-49275wazuhWazuh vulnerable to NULL Pointer Dereference in wazuh-analysisdWazuh is a free and open source platform used for threat prevention, detection, and response. A NULL pointer dereference was detected during fuzzing of the analysis engine, allowing malicious clients to DoS the analysis engine. The bug occurs when `analysisd` receives a syscollector message with the `hotfix` `msg_type` but lacking a `timestamp`. It uses `cJSON_GetObjectItem()` to get the `timestamp` object item and dereferences it without checking for a `NULL` value. A malicious client can DoS the analysis engine. This vulnerability is fixed in 4.7.1.EPSS0.88%HighCVE-2023-50260wazuhWazuh's vulnerability in host_deny AR script allows arbitrary command executionWazuh is a free and open source platform used for threat prevention, detection, and response. A wrong validation in the `host_deny` script allows to write any string in the `hosts.deny` file, which can end in an arbitrary command execution on the target system. This vulnerability is part of the active response feature, which can automatically triggers actions in response to alerts. By default, active responses are limited to a set of pre defined executables. This is enforced by only allowing executables stored under `/var/ossec/active-response/bin` to be run as an active response. However, the `/var/ossec/active-response/bin/host_deny` can be exploited. `host_deny` is used to add IP address to the `/etc/hosts.deny` file to block incoming connections on a service level by using TCP wrappers. Attacker can inject arbitrary command into the `/etc/hosts.deny` file and execute arbitrary command by using the spawn directive. The active response can be triggered by writing events either to the local `execd` queue on server or to the `ar` queue which forwards the events to agents. So, it can leads to LPE on server as root and RCE on agent as root. This vulnerability is fixed in 4.7.2.EPSS41.16%
