CVE-2026-854328.2 HIG—
———MOOS core-moos through 10.4.0 fails to validate client identity in MOOSDB message processing, allowing authenticated attackers to attribute writes to other clients by supplying arbitrary source identifiers in serialized messages. Attackers can forge message origins and cancel third-party subscriptions by exploiting the disconnect between authenticated connection identity and wire-supplied source attribution.10hCVE-2026-847665.9 MED—

———In Eclipse Arrowhead versions from 5.0.0 to 5.2.1 when the MQTT API is enabled with the certificate authentication policy, CertificateMqttFilter parses an X.509 certificate that the client sends inside the MQTT message payload (the authentication field of MqttRequestTemplate) and treats its Subject DN as the authenticated identity. The certificate is decoded with CertificateFactory.generateCertificate() but its signature is never verified and its issuer chain is never validated against any trust store. Authorisation is reduced to two string comparisons on attacker-supplied data: the DN-qualifier must equal "sy" or "op", and the cloud-name part of the CN must match the server's. Both values are public (the cloud name is in the server's own TLS certificate). An attacker who can publish to the MQTT broker can therefore mint a self-signed certificate with CN=Sysop.<cloud>.<org>.arrowhead.eu, dnQualifier=op, send it as the authentication field, and be authenticated as the cloud's system operator with isSysOp == true. This passes the downstream ManagementServiceMqttFilter (request.isSysOp() → allowed) and gives full management access over MQTT. The HTTP CertificateFilter is not affected — it reads the certificate from jakarta.servlet.request.X509Certificate, which Tomcat populates only after a successful mTLS handshake against the configured trust store.17hCVE-2026-191179.8 CRI—
——0Under specific conditions, an attacker can register an attacker-controlled FIDO2 credential against a target account and then authenticate as
that user. This issue affects on-premises deployments only.17hCVE-2026-141997.1 HIG—
——0Only self-managed Grafana instances with Auth Proxy authentication and identity caching enabled (sync_ttl greater than zero) are affected. The Auth Proxy cache key concatenated the username and forwarded identity attributes without a delimiter, so distinct identities could collide on one key. An authenticated user who shapes their own attributes to collide with a higher-privileged user's, while that user's cache entry is live, is authenticated as that user, up to Administrator (authentication bypass by spoofing).17hCVE-2026-844799.1 CRI24.2%
——7WWBN AVideo (current e01e41ecc and earlier) makes three login-time security controls depend solely on the client-supplied User-Agent header. The isAVideoEncoder()/isAVideoMobileApp() checks match HTTP_USER_AGENT against a hardcoded literal ("AVideoEncoder"/"AVideoMobileApp") with no IP check or shared secret. An attacker who submits valid credentials and sets User-Agent: AVideoEncoder bypasses two-factor authentication, skips brute-force captcha escalation, and avoids being recorded in the login/device audit history. No patch is available at the time of publication.2d
