Bulletin ID: 2026-006-AWS Scope: AWS Content Type: Informational Publication Date: 2026/03/03 10:15 AM PST Description: Amazon RDS/Aurora is a managed relational database service. We identified CVE-2026-3494. In MariaDB server version through 11.8.5, when server audit plugin is enabled with server_audit_events variable configured with QUERY_DCL, QUERY_DDL, or QUERY_DML filtering, if an authenticated database user invokes a SQL statement prefixed with double-hyphen (‐‐) or hash (#) style comments, the statement is not logged. Impacted versions: - MariaDB Server (10.6.24 and prior, 10.11.15 and prior, 11.4.9 and prior, and 11.8.5 and prior) - Amazon Aurora MySQL (2.12.5 and prior, 3.01.0 to 3.04.5, 3.05.1 to 3.10.2, and 3.11.0) - Amazon RDS for MySQL (5.7.44-RDS.20251212 and prior, 8.0.11 to 8.0.44, and 8.4.3 to 8.4.7) - Amazon RDS for MariaDB (10.6.24 and prior, 10.11.4 to 10.11.15, 11.4.3 to 11.4.9, and 11.8.3 to 11.8.5) Please refer to the article below for the most up-to-date and complete information related to this AWS Security Bulletin.

Bitwarden Server before 2026.7.2 does not verify that the caller is a member of the organization identified in a POST /collect request body, allowing any authenticated user to write forged, arbitrarily backdated entries into any organization's audit log.

Improper access control in Hashtopolis server web-interface chunk activity component for versions prior to 0.14.8 allows any created account to read all cracked hashes of a Hashtopolis server instance.

Nextcloud Server is a self hosted personal cloud system. In Nextcloud Server and Enterprise Server prior to 30.0.9 and 31.0.1, incorrect path handling with groupfolders caused the admin_audit app to not properly log all actions on files and folders inside groupfolders. This vulnerability is fixed in Nextcloud Server and Enterprise Server prior to 30.0.9 and 31.0.1.

Nextcloud Server is a self hosted personal cloud system. In Nextcloud Server prior to 31.0.10 and 32.0.1 and Nextcloud Enterprise Server prior to 28.0.14.11, 29.0.16.8, 30.0.17.3, and 31.0.10, contacts search allowed to retrieve personal data of other users (emails, names, identifiers) without proper access control. This allows an authenticated user to retrieve information about accounts that are not related or added as contacts.

Nextcloud is an open source content collaboration platform. In Nextcloud Server from versions 32.0.0 to before 32.0.9, and 33.0.0 to before 33.0.3, a pre-2FA session cookie (created after successful password authentication but before TOTP completion) could be reused as a Bearer token to authenticate against DAV endpoints, granting read/write access and bypassing mandatory two-factor authentication. It is recommended that the Nextcloud Server is upgraded to 33.0.3 or 32.0.9. It is recommended that the Nextcloud Enterprise Server is upgraded to 33.0.3, 32.0.9, 31.0.14.5, 30.0.17.9 or 29.0.16.16

Nextcloud is an open source content collaboration platform. In Nextcloud Server from versions 32.0.0 to before 32.0.9, and 33.0.0 to before 33.0.3, an authentication bypass vulnerability allowed attackers with knowledge of a user's password to circumvent two-factor authentication (2FA) protections. When a user initiated login with valid credentials on a 2FA-enabled account, the system created a temporary session token before enforcing the second factor challenge. This token could be extracted and replayed via HTTP Basic Authentication to gain unauthorized access to authenticated endpoints. It is recommended that the Nextcloud Server is upgraded to 33.0.3 or 32.0.9. It is recommended that the Nextcloud Enterprise Server is upgraded to 33.0.3, 32.0.9, 31.0.14.5, 30.0.17.9 or 29.0.16.16

Nextcloud is an open source content collaboration platform. In Nextcloud Server from versions 32.0.0 to before 32.0.9, and 33.0.0 to before 33.0.3, with the knowledge of other users’ principal URL an attacker could possibly send a request to gain full access to their calendar. Therefore, the attacker must be an authenticated user. This is because of improper authorization controls in the backend of the calendar. If the attacker had access to the calendar, they would be able to view and modify it. It is recommended that the Nextcloud Server is upgraded to 33.0.3 or 32.0.9. It is recommended that the Nextcloud Enterprise Server is upgraded to 33.0.3, 32.0.9, 31.0.14.5, 30.0.17.9, 29.0.16.16, 28.0.14.17, 27.1.11.26, 26.0.13.26, 25.0.13.29, 24.0.12.34, 23.0.12.35, 22.2.10.39, or 21.0.9.23

Nextcloud Server and Enterprise Server versions prior to 31.0.1 contain an authorization bypass vulnerability (CVE-2025-66547) that allows non-privileged users to modify tags on files they should not have access to via bulk tagging. This issue is fixed in version 31.0.1. The vulnerability has a medium severity with a CVSS score of 4.3.

Bitwarden Server before 2026.6.0 does not verify that the email in a POST /auth-requests/admin-request body belongs to the authenticated caller, allowing a low-privileged organization member to obtain another user's vault key and a victim-scoped access token by creating a Trusted Device Encryption authentication request, bound to an attacker-controlled public key, that is readable from an unauthenticated endpoint once approved resulting in disclosure of the victim's vault key and account takeover.
