Wazuh Vulnerable to Heap-based Buffer Over-read in DecodeWinevt
Wazuh is a free and open source platform used for threat prevention, detection, and response. Prior to 4.10.2, a buffer over-read occurs in DecodeWinevt() when child_attr[p]->attributes[j] is accessed, because the corresponding index (j) is incorrect. A compromised agent can cause a READ operation beyond the end of the allocated buffer (which may contain sensitive information) by sending a specially crafted message to the wazuh manager. An attacker who is able to craft and send an agent message to the wazuh manager can cause a buffer over-read and potentially access sensitive data. While the buffer over-read is always triggered while resolving the arguments of mdebug2, specific configuration options (analysisd.debug=2) need to be in place for the respective data to be leaked. This vulnerability is fixed in 4.10.2.

CWE-124 Oct 29, 2025
Wazuh Vulnerable to Heap-based Buffer Out-Of-Bounds WRITE in decode_win_permissions
Wazuh is a free and open source platform used for threat prevention, detection, and response. A heap-based out-of-bounds WRITE occurs in decode_win_permissions, resulting in writing a NULL byte 2 bytes before the start of the buffer allocated to decoded_it. A compromised agent can potentially leverage this issue to perform remote code execution, by sending a specially crafted message to the wazuh manager. An attacker who is able to craft and send an agent message to the wazuh manager can leverage this issue to potentially achieve remote code execution on the wazuh manager (the exploitability of this vulnerability depends on the specifics of the respective heap allocator). This vulnerability is fixed in 4.10.2.

CWE-252 Oct 29, 2025
Wazuh fillData NULL pointer dereference causes analysisd crash
Wazuh is a free and open source platform used for threat prevention, detection, and response. fillData() implementation does not check whether value is NULL or not before calling os_strdup() on it. A compromised agent can cause a crash of analysisd by sending a specially crafted message to the wazuh manager. An attacker who is able to craft and send an agent message to the wazuh manager can cause analysisd to crash and make it unavailable. This vulnerability is fixed in 4.10.2.

CWE-122 Sep 26, 2025
Heap buffer overflow in wazuh-analysisd
Wazuh is a free and open source platform used for threat prevention, detection, and response. In versions starting from 3.8.0 to before 4.11.0, wazuh-analysisd is vulnerable to a heap buffer overflow when parsing XML elements from Windows EventChannel messages. This issue has been patched in version 4.11.0.

Wazuh Server Deserialization of Untrusted Data Vulnerability
Wazuh is a free and open source platform used for threat prevention, detection, and response. Starting in version 4.4.0 and prior to version 4.9.1, an unsafe deserialization vulnerability allows for remote code execution on Wazuh servers. DistributedAPI parameters are a serialized as JSON and deserialized using `as_wazuh_object` (in `framework/wazuh/core/cluster/common.py`). If an attacker manages to inject an unsanitized dictionary in DAPI request/response, they can forge an unhandled exception (`__unhandled_exc__`) to evaluate arbitrary python code. The vulnerability can be triggered by anybody with API access (compromised dashboard or Wazuh servers in the cluster) or, in certain configurations, even by a compromised agent. Version 4.9.1 contains a fix.
