CVE-2026-781547.3 HIG—
———A vulnerability was identified in the-momentum open-wearables up to 0.6.2. This impacts the function redeem_invitation_code of the file backend/app/api/routes/v1/user_invitation_code.py of the component Public Invitation-Code Redemption Endpoint. The manipulation of the argument code leads to missing authentication. Remote exploitation of the attack is possible. The project was informed of the problem early through an issue report but has not responded yet.9hCVE-2026-598088.8 HIG—
——0AVideo through commit 9c39d8c8 contains an authentication bypass vulnerability where deduplicateByEncoderQueueId() returns video_id_hash credentials for any video by encoder_queue_id without ownership verification, and useVideoHashOrLogin() converts this hash into passwordless login as the video owner. Attackers with upload permission can retrieve an administrator's video_id_hash by omitting the videos_id parameter, then use that hash in an unauthenticated request to gain administrative session access and modify system configuration.2dCVE-2026-48106—5.4%
——2Arc is an open, SQL-native time-series database for telemetry. Prior to version 26.06.1, Arc Enterprise's cluster replication receiver at `internal/cluster/replication/receiver.go` validates only the wire-format envelope (length, opcode) of inbound messages. The `MsgReplicateSync` payload itself is accepted without any application-layer authentication — no HMAC, no signature, no per-message nonce. The replication stream is protected at the transport layer by TLS / mTLS, but there is no protection against application-layer message tampering or replay once a peer is on the cluster network. This is fixed in 2026.06.1. Some workarounds are available. Restrict cluster network access to known-trusted peers via strict firewall rules, audit replication logs for unexpected `MsgReplicateSync` traffic, and/or disable cluster mode until the fix is available.2dCVE-2026-48050—29.2%
——9Arc is an open, SQL-native time-series database for telemetry. Versions prior to 26.06.1 register Go's `net/http/pprof` handlers at `/debug/pprof/*` via `app.Use(pprof.New())` in `internal/api/server.go`, and `/debug/pprof` is added to `PublicPrefixes` in `cmd/arc/main.go`. The auth middleware short-circuits before the token check on prefix match, so the endpoints are reachable without any authentication. Version 26.06.1 contains a patch. Some workarounds are available. Block `/debug/pprof*` at a reverse proxy / load balancer in front of Arc, restrict Arc's API port to known-trusted networks via firewall rules, and/or patch the running build: comment out `app.Use(pprof.New())` in `internal/api/server.go` and rebuild.2dCVE-2026-349496.5 MED12.9%
——4Combodo iTop is a web based IT service management tool.Prior to 3.2.3, an unauthenticated user could delete the .readonly file on iTop instances — a file created during the setup process that prevents users from performing write actions. This issue has been fixed in version 3.2.3.2dCVE-2026-347418.6 HIG37.5%
——11Combodo iTop is a web based IT service management tool. Prior to 3.2.3, authentication bypass allows unauthenticated remote attackers to execute arbitrary PHP files from the env-production directory on a new iTop instance in the production environment. This issue has been fixed in version 3.2.3.2d
