SeaweedFS is a distributed storage system for files and blobs. In versions prior to 4.40, an authenticated S3 principal with permissions scoped to a nested object key can overwrite a different object outside that scope by calling PutObjectAcl on the key it is allowed to access. The handler authorizes the request against the requested nested key but then writes the updated entry back to the bucket root rather than the key's actual parent directory, so an ACL change on allowed/protected.txt is instead applied to protected.txt at the bucket root. Because the update carries the full entry rather than only ACL metadata, an existing target object is overwritten with the content, metadata, owner information, and ACL of the scoped object, bypassing the object-level action scoping configured through the static S3 identity file. This issue is fixed in version 4.40.

CVE-2026-817296.5 MED—
———Dolibarr before 23.0.4 authorizes REST API document deletion against the wrong permission. Documents::delete() in htdocs/api/class/api_documents.class.php calls dol_check_secure_access_document() with the mode argument 'read' when handling DELETE /api/index.php/documents, while the sibling builddoc() path passes 'write', the correct mode for an operation that modifies stored data. An authenticated API user who holds only a read permission for a document-bearing module, for example societe:lire or facture:lire, and no create, write, delete or admin permission, therefore passes the check and can permanently delete that module's documents: third-party files, invoices, orders, proposals, project files and generated PDFs, with no recovery path. The call site is htdocs/api/class/api_documents.class.php:1276 in 23.0.3 and passes 'write' from 23.0.4 onward.5hCVE-2026-774387.5 HIG—
———Trilium is an open-source hierarchical note-taking application. In versions up to and including 0.103.0, the public share-search endpoint does not enforce the per-note shareCredentials and shareHiddenFromTree controls, allowing an unauthenticated visitor to read the titles, tree paths, and content of protected shared notes. The endpoint authorizes only the ancestor note supplied in the request and then runs a full-text search across the entire published subtree, returning each matching note's title, share identifier, and hierarchical path without re-checking whether that individual note requires a share password or is hidden from the navigation tree. Because the search matches note content, an attacker can enumerate protected notes and use the endpoint as a boolean oracle that confirms arbitrary substrings, recovering the full contents of notes that should be gated behind a password. This issue is fixed in version 0.104.0.5hCVE-2026-802094.3 MED—
———The updateWorkspace handler in mods/identity/src/workspaces/createUpdateWorkspace.ts in Fonoster through 0.22.7 invokes the gRPC callback with PERMISSION_DENIED when createIsWorkspaceMember reports that the caller is not a member of the target workspace, but it does not return. Execution continues into prisma.workspace.update, which is scoped by the workspace reference alone, so the rename commits before the second callback is issued and the caller receives a permission error for a write that already succeeded. The gRPC interceptor in mods/common/src/identity/createAuthInterceptor.ts binds the workspace accessKeyId to the caller's token only for paths in workspaceResourceAccess or workspaceResourceOwnerOrAdminAccess, and Identity/UpdateWorkspace is listed in fullIdentityAccess, which the base USER role holds. Any authenticated user can therefore rename an arbitrary workspace in the deployment.5hCVE-2026-194544.4 MED—
———The JetBackup WordPress plugin before 3.1.23.5 does not perform its multisite authorisation check before serving backup archives and job logs, allowing an administrator of the network's main site who is not a Super Admin to download a full backup of the entire network, including every site's data and the shared webroot.8hCVE-2026-77298——
———SeaweedFS is a distributed storage system for files and blobs. In versions 4.39 and earlier, the S3 API accepts an external OIDC JWT sent directly in the Authorization header and maps it to an IAM role without enforcing that role's trust policy, so a federated user can assume a role they are not permitted to hold. The standard STS AssumeRoleWithWebIdentity path rejects such a token when the role's trust policy does not trust the token's federated provider, but the direct S3 bearer path validates only the token itself and then authenticates as the mapped role and evaluates that role's attached S3 permissions. As a result, a valid OIDC user whose token would be denied the role through STS can obtain the role's S3 access, including object read, write, and delete, by presenting the raw OIDC JWT directly to the S3 API. This issue is fixed in version 4.408hCVE-2026-775075.3 MED—
———Weblate is a web-based continuous localization platform used to manage software translations. In versions prior to 2026.8, Weblate's object-scoped RSS feeds do not apply the permission checks used elsewhere, allowing unauthorized users to read change-history metadata from private projects and restricted components. On installations that permit anonymous access, this metadata can be retrieved without any authentication. The exposed information can include project and component identities, contributor usernames and full names, action types, timestamps, and translation or unit links, though translated-string content is not included in the feed. Installations using private projects or restricted components are affected. This issue is fixed in version 2026.8.8h
