CVE-2026-15754 1 Mattermost 2 Mattermost, Mattermost Server 2026-08-18 4.2 Medium
Mattermost versions 11.7.x <= 11.7.6, 11.8.x <= 11.8.3 The access control policy unassign endpoint fails to re-validate that each target channel still belongs to the requesting admin's team, which allows an authenticated team administrator to remove ABAC (attribute-based access control) policy assignments from channels outside their team via the policy unassign API after a channel has been moved to another team.. Mattermost Advisory ID: MMSA-2026-00718
CVE-2026-48508 1 Netflix 1 Lemur 2026-08-18 8.8 High
Lemur manages TLS certificate creation. Prior to 1.9.1, StrictRolePermission and AuthorityCreatorPermission in lemur/auth/permissions.py call flask_principal.Permission.__init__() with zero Need objects when ADMIN_ONLY_AUTHORITY_CREATION and LEMUR_STRICT_ROLE_ENFORCEMENT are unset because both flags default to False. Flask-Principal Permission.allows() returns True when self.needs is empty, so the .can() authorization gate permits every authenticated identity, including the read-only role. A read-only user can access POST /api/1/authorities, POST /api/1/certificates/upload, POST /api/1/pending_certificates//upload, POST /api/1/notifications, PUT or DELETE /api/1/notifications/, and POST /api/1/domains to create root Certificate Authorities, upload arbitrary certificates, create or edit notifications that reach an SSRF sink, and create domain entries. Explicitly setting either flag to False continues to opt into the permissive behavior. This issue is fixed in version 1.9.1.
CVE-2026-45121 1 Mybb 1 Mybb 2026-08-18 4.3 Medium
MyBB is free and open source forum software. Prior to 1.8.40, the calendar module does not check permissions consistently when listing calendars, allowing authenticated users to access titles of calendars that are otherwise inaccessible. The affected calendar-selection paths in calendar.php perform permission checks against an invalid calendar context before returning calendar titles. The uniquely identifying implementation details include titles of inaccessible calendars, and invalid calendar permission context. This issue is fixed in version 1.8.40.
CVE-2026-45122 1 Mybb 1 Mybb 2026-08-18 4.3 Medium
MyBB is free and open source forum software. Prior to 1.8.40, the calendar module does not validate moderation permissions for the destination calendar when moving events. A user with moderation permission for the source calendar can move an event to a calendar where the user has only viewing permission because the do_move action in calendar.php does not check canmoderateevents for the target calendar. The uniquely identifying implementation details include calendar event move, source calendar moderation permission, and destination calendar viewing permission. This issue is fixed in version 1.8.40.
CVE-2026-75480 1 Volcengine 1 Openviking 2026-08-18 6.5 Medium
OpenViking debug vector scroll and count endpoints apply only account-level scoping without user-level access controls, allowing authenticated users to read all co-tenant records. Attackers can query these endpoints to retrieve private memories, resources, skills, and secret material belonging to other users in the same account without administrative privileges.
CVE-2026-71518 1 Typemill 1 Typemill 2026-08-18 7.5 High
Typemill before 2.26.0 contains an authorization bypass vulnerability in the media file download route that allows unauthenticated attackers to access restricted files by submitting path-equivalent URL variants. Attackers can substitute normalized path forms such as dot-slash prefixes, double slashes, or percent-encoded sequences to pass role-based restriction checks while the filesystem resolves the request to the protected file, enabling unauthorized file download without credentials.
CVE-2026-44846 1 Jumpserver 1 Jumpserver 2026-08-18 6.2 Medium
JumpServer is an open source bastion host and an operation and maintenance security audit system. Prior to 4.10.17, a user with the users.invite_user permission can submit an existing member to POST /api/v1/users/users/invite/, causing the organization invitation logic in apps/users/api/user.py to execute user.org_roles.set(org_roles) and replace the member's existing organization roles, which can escalate privileges or downgrade administrators. This issue is fixed in version 4.10.17.
CVE-2026-16046 1 Mattermost 1 Mattermost 2026-08-18 3.5 Low
Mattermost versions 11.7.x <= 11.7.6, 10.11.x <= 10.11.21 fail to enforce run-state validation on write operations for finished playbook runs which allows a run participant to modify status, checklists, retrospective content, ownership, and participants on completed runs via REST and GraphQL API requests. Mattermost Advisory ID: MMSA-2026-00675
CVE-2026-73305 1 Budibase 1 Budibase 2026-08-18 8.8 High
Budibase is an open-source low-code platform. Prior to 3.39.24, POST /api/public/v1/roles/assign called validateGlobalRoleUpdate without checking appBuilder.appId or role.appId in packages/server/src/api/controllers/public/globalRoleValidation.ts. An app-scoped builder could scope the request to an app they control and then grant themselves builder access or an arbitrary role in another app, exposing that app data, datasource configuration, and automations. This issue is fixed in version 3.39.24.
CVE-2026-73049 2 B3log, Siyuan 2 Siyuan, Siyuan 2026-08-18 5.8 Medium
SiYuan versions before v3.7.4 contain an information disclosure vulnerability in the getAttributeViewBacklinks endpoint that consults the forbidden access list instead of the visibility list when filtering backlinks. Anonymous readers can supply a publicly visible database row identifier to discover hidden-tier documents that reference it, receiving the database name, row title, and document path of hidden documents.
CVE-2026-19726 2026-08-17 6.5 Medium
The Visualizer WordPress plugin before 4.0.7 does not properly authorise access to the configuration of its charts, allowing users with the Contributor role and above to read the full configuration of any chart on the site, including charts the Visualizer WordPress plugin before 4.0.7's own interface denies them, and to retrieve every chart's configuration in a single request. The disclosed configuration can include the credentials of a remote data source a chart reads from.
CVE-2026-59851 2 Libssh, Redhat 4 Libssh, Enterprise Linux, Hardened Images and 1 more 2026-08-17 8.8 High
A flaw was found in libssh. On servers with GSSAPIKeyExchange enabled, the gssapi-keyex path does not verify whether the authenticated Kerberos principal is authorized for the requested local user, allowing authenticated clients to log in as arbitrary users.
CVE-2026-74248 1 Openstack 1 Octavia 2026-08-17 4.3 Medium
OpenStack Octavia through 18.0.0 mishandles quality of service (QoS) policy authorization. By associating another project's QoS policy with an amphora, an authenticated user may prevent deletion of that policy. All Octavia deployments are affected.
CVE-2026-61925 1 Microsoft 26 Windows 10 1607, Windows 10 1809, Windows 10 21h2 and 23 more 2026-08-17 7.8 High
Incorrect authorization in Windows Installer allows an authorized attacker to elevate privileges locally.
CVE-2026-54698 1 Hasura 1 Graphql Engine 2026-08-17 5.9 Medium
Hasura is an open-source product that provides users GraphQL or REST APIs. Prior to 2.49.2 and 2.45.5, a user can use a where clause on a table computed field (returning SETOF some_table) to infer row values that ought to be filtered for their role based on some_table's row-level permissions. While such rows cannot be returned directly, like predicates on strings for instance allow values to be brute forced efficiently with the where clause as an oracle. This issue is fixed in versions 2.49.2 and 2.45.5.
CVE-2026-16045 1 Mattermost 1 Mattermost 2026-08-17 2.7 Low
Mattermost versions 11.7.x <= 11.7.6, 10.11.x <= 10.11.21 Mattermost failed to restrict OAuth deauthorization and personal access token management endpoints to direct user sessions, which allowed an OAuth app with a delegated user token to revoke the user's authorizations or tokens for other integrations via account-management endpoints.. Mattermost Advisory ID: MMSA-2026-00704
CVE-2026-16044 1 Mattermost 1 Mattermost 2026-08-17 3.9 Low
Mattermost versions 11.7.x <= 11.7.6, 10.11.x <= 10.11.21 fail to prevent guest users from receiving Board Admin privileges during board archive import which allows a board member to escalate a guest user to Board Admin via importing a crafted .boardarchive file. Mattermost Advisory ID: MMSA-2026-00672
CVE-2026-10527 1 Mattermost 1 Mattermost 2026-08-17 6.3 Medium
