CVE-2026-109833

MEDIUM5.9

Published 2026-10-13 · Updated 2026-10-13 · Source secalert@redhat.com

Description

A flaw was found in gnome-remote-desktop as shipped in Red Hat Enterprise Linux. In the VNC TLS read path, partial consumption of the internal peek buffer incorrectly moves remaining peeked bytes into the caller-supplied buffer instead of compacting the peek buffer. A remote attacker who can reach an enabled VNC TLS listener and trigger a peek/read size mismatch can cause an out-of-bounds write, leading to denial of service.

CVE-2026-93347
Wazuh from 4.1.1 before 4.14.8 contains a path traversal vulnerability in the get_list_file helper that allows malicious cluster workers to read arbitrary files via unvalidated filename values. Attackers holding the cluster key can send DistributedAPI requests with traversal filenames to read client.keys, ossec.conf with the cluster key, and other wazuh-readable files.

CVE-2026-93346
Wazuh from 4.0.0 before 4.14.8 contains a race condition in API login throttling that allows unauthenticated attackers to bypass max_login_attempts by sending concurrent requests. Attackers can fire concurrent login bursts to the authenticate and run_as endpoints, each passing the block check before failures are counted, enabling unlimited password guessing.

CVE-2026-77362
obsidian-tc is a governed, agent-ready Model Context Protocol server for Obsidian vaults. Prior to 1.3.1, bridge tools do not consistently apply the read access-control list (ACL) to every returned field. The tasks_filter tool exposes group counts derived from denied notes, makemd_query passes unfiltered sibling result fields through, and list_templates exposes template paths and parsed user-function bodies without a read-whitelist check. An authenticated caller can consequently infer or read data from notes outside the caller's read ACL. Version 1.3.1 fixes the vulnerability by filtering path-attributable fields and applying the read whitelist to list_templates.

CVE-2026-77361
obsidian-tc is a governed, agent-ready Model Context Protocol server for Obsidian vaults. Prior to 1.3.1, read access-control list (ACL) checks use a lexical vault-relative path while containment checks use the resolved path. An in-vault symlink under an allowed glob that resolves into a denied folder can therefore bypass the read ACL and expose files in the denied folder. Exploitation requires an out-of-band-planted symlink and does not permit an escape from the vault root. Version 1.3.1 fixes the vulnerability by applying ACL checks to the resolved vault-relative path.

CVE-2026-74047
Wazuh from 4.0.0 before 4.14.8 contains an information disclosure vulnerability that allows low-privileged users with agent:read to retrieve the plaintext authd.pass enrollment password via the unmasked agent configuration endpoint. Attackers holding the default readonly role can request the auth component configuration for pseudo-agent ID 000 to obtain the secret and enroll rogue agents against the manager.
