Descripción técnica

LangGraph Checkpoint Postgres and SQLite Checkpoint are the Postgres and SQLite implementations of LangGraph's checkpoint saver. Prior to 3.1.1, the langgraph-checkpoint-postgres and langgraph-checkpoint-sqlite packages persisted hierarchical namespaces as a dot joined string and scoped reads by matching that string as a simple prefix pattern, so a read scoped to one namespace could also match a sibling namespace whose flattened form shares the same leading characters, or a namespace label containing unescaped pattern metacharacters, allowing an authenticated caller to retrieve stored items belonging to another tenant or user through an ordinary scoped search or list namespaces call, with no crafted input required. This issue is fixed in versions 3.1.1 of langgraph-checkpoint-postgres and langgraph-checkpoint-sqlite.

———A flaw was found in udisks2. A local attacker with an active console session can exploit insufficient authorization checking on the 'as-user' option in the org.freedesktop.UDisks2.Filesystem.Mount() D-Bus method. This allows the attacker to spoof the 'as-user' parameter, mounting filesystems on behalf of arbitrary users, including privileged accounts. This can lead to local privilege escalation through mount point injection and manipulation of the mount namespace visible to privileged users.3h CVE-2026-71325—

———Traefik is an open-source edge router that makes publishing services a fun and easy experience. Prior to 2.11.54, 3.6.25, and 3.7.10, cross-namespace @kubernetescrd references are not rejected for TraefikService backend references resolved by the service resolver. A tenant confined by RBAC to a single namespace can therefore bind its own router to a TraefikService owned by another namespace and expose or reroute that namespace's backend, defeating the namespace isolation allowCrossNamespace=false is meant to enforce. This issue is fixed in version 2.11.54, 3.6.25, 3.7.10.3h CVE-2026-646644.3 MED

———Statamic is a Laravel and Git powered content management system (CMS). Prior to 5.74.1 and 6.24.0, an authenticated Control Panel user could use an endpoint intended for the user creation wizard to determine if a given email address belonged to an existing user, without having permission to view users, though the endpoint only exposed user existence and not any other user data. This issue is fixed in versions 5.74.1 and 6.24.0.3h CVE-2026-480808.0 ALT

———OpenReception's appointment booking software provides an end-to-end encrypted appointment booking platform. Prior to version 1.0.2, the `GET /api/tenants/{id}` endpoint returns the full tenant record to any authenticated `TENANT_ADMIN` of that tenant, including the `databaseUrl` field. This field contains the live PostgreSQL connection string the application uses to connect to that tenant's database. In the tested official `docker-compose.prod.yml` deployment, the connection string contained the user `postgres` with `rolsuper=true` and the plaintext password from `secrets/postgres_password.txt`. Operators who configure a non-superuser PostgreSQL user via `secrets/postgres_user.txt` would expose a less privileged credential, but the disclosure of the connection string itself is independent of that choice. The same credential applies to every database managed by that PostgreSQL instance: the central `appointment_booking` database, every per-tenant database (one per tenant), and the postgres administrative database. A `TENANT_ADMIN` of one tenant who can reach `postgres:5432` (directly via internal network, indirectly via any SSRF, RCE, or file-read in the application) can read every other tenant's appointment ciphertexts, key shares, and metadata; read the central user table, including all `GLOBAL_ADMIN` accounts, password hashes, and session records; modify or delete any data in any tenant database; and/or i a superuser-scoped deployment: use PostgreSQL's `pg_read_server_files`, `COPY ... FROM PROGRAM`, and `CREATE EXTENSION` for further escalation inside the database container. This breaks the per-tenant database isolation that is otherwise the primary cross-tenant control in the application. The application code carefully scopes most queries to the calling tenant's database, but those scopings are irrelevant once the attacker holds the credentials that bypass the application entirely. Version 1.0.2 fixes the issue.3h CVE-2026-480785.3 MED

———OpenReception's appointment booking software provides an end-to-end encrypted appointment booking platform. Prior to version 1.0.5, the unauthenticated `/api/tenants/{id}/schedule` endpoint returns every non-archived channel for a tenant regardless of the channel's `isPublic` flag. Channels marked `isPublic = false` are intended to be invisible to public callers; the dashboard creates them deliberately to hide internal-only services from the patient booking UI. The schedule endpoint ignores the flag entirely and discloses channel names, descriptions, IDs, agent associations, pause status, confirmation requirements, and computed slot availability for the requested date range. The asymmetry between `addAppointmentToTunnel` (which enforces `eq(channel.isPublic, true)`) and the schedule endpoint (which does not) confirms the design intent: private channels exist as a real access boundary in the booking flow, just not in the schedule disclosure. Version 1.0.5 patches the issue.3h CVE-2026-480766.5 MED

———OpenReception's appointment booking software provides an end-to-end encrypted appointment booking platform. The new-client booking flow in versions 1.0.1 and prior consists of three calls: `bootstrap-challenge` (returns a 16-bit PoW challenge with `difficulty=4` leading hex zeroes), `bootstrap-verify` (validates the PoW and issues a Bearer booking access token), and `create-new-client` (consumes the token and creates the tunnel and first appointment). The token correctly binds to `tenantId`, `tunnelId`, `clientPublicKey`, and `emailHash`, but never to `channelId`. The `bootstrap-challenge` request schema does not even accept a `channelId`, and the issued token's payload contains no channel information. Independently, the service function `createNewClientWithAppointment` checks only `channel.archived = false`. The `channel.isPublic` check that protects `addAppointmentToTunnel` is missing in the new-client path. The combination means: an attacker completes the bootstrap flow normally (16-bit PoW, completes in well under one second on commodity hardware, no rate limiting beyond the throttle store), receives a valid booking access token, and then submits the `create-new-client` payload with `channelId` pointing to a private (`isPublic = false`) channel. The booking lands as `CONFIRMED` if the target channel has `requiresConfirmation = false` (the default), otherwise as `NEW`. The patient-facing UI does not list private channels in its picker (`/api/public/channels` correctly filters `isPublic = true`), so the channel ID must be obtained out of band. The companion finding V-10 (schedule endpoint discloses private channels) provides exactly that: a single unauthenticated GET reveals every private channel ID for any tenant. V-10 plus V-11 together make private channels fully reachable to anonymous attackers. As of time of publication, no known patched versions are available.3h
