CVE-2026-48024

CRITICAL9.1

Published 2026-08-19 · Source security-advisories@github.com

Description

Wazuh is a free and open source platform used for threat prevention, detection, and response. From 4.0.0 until 4.14.6 and 5.0.0-beta3, cluster.unmerge_info() in framework/wazuh/core/cluster/cluster.py constructs paths from peer-controlled merge_type and name values in a merged synchronization archive. process_files_from_worker() in framework/wazuh/core/cluster/master.py does not adequately confine the resulting path to the declared cluster item directory. A cluster peer holding the shared Fernet key can use traversal in files_metadata.json or a merged-file header to write files such as /var/ossec/etc/ossec.conf. Replacing ossec.conf can configure root-executed commands and lead to code execution when Wazuh services reload. This issue is fixed in versions 4.14.6 and 5.0.0-beta3.

CVE-2026-66794
A flaw was found in the `cluster-proxy-addon` component of Multicluster Engine for Kubernetes. This vulnerability allows an unauthenticated attacker, who can access the user-facing route, to bypass authentication and authorization checks. By manipulating URL path segments, the attacker can proxy requests to arbitrary services across any managed cluster. This enables unauthorized access to internal services that would otherwise be protected, potentially leading to information disclosure or further compromise of the cluster environment.

CVE-2026-75143
FFmpeg before commit 1c10bcc contains a heap buffer overflow in the RIST protocol reader (libavformat/librist.c). librist_read() ignored its size argument and copied the full received payload length into the caller-provided destination buffer, overflowing it when the payload exceeds the destination size. This is reachable via the async:rist:// URL scheme, where the async wrapper supplies a smaller buffer than the received payload. A remote RIST sender can trigger the overflow by sending a packet whose payload exceeds the caller buffer size.
