CVE-2026-116485
danmu_api before 1.21.7 contains an authentication bypass vulnerability that allows unauthenticated attackers to modify server environment configuration when the default TOKEN is used and ADMIN_TOKEN is unset. Attackers can send POST requests to /api/env/set, /api/env/add, or /api/env/del to set ADMIN_TOKEN, lock out operators, redirect OTHER_SERVER or PROXY_URL for SSRF, and trigger redeployment.
-
CVE-2026-75128
Langchain-Chatchat through 0.3.1.3 exposes a POST /tools/call API endpoint that invokes any registered tool by name without authentication, leaving the always-registered shell tool callable. Remote attackers can send a single request naming the shell tool to execute arbitrary OS commands as the server user (root in the shipped Docker image).

CVE-2026-59105
Jumis (formerly Tildes Jumis) creates and uses a Microsoft SQL Server login named ##Tilde_JumisAdmin## whose password is derived deterministically from a single non-secret input - the SQL Server name (@@servername). The derivation algorithm is hard-coded in the client application and is identical across every installation; it contains a hard-coded secret key for entropy. Because the only input (the server name) is not secret - the instance suffix is hard-coded and the host name is discoverable via the SQL Server Browser service (UDP 1434), the TDS pre-login response, or DNS/NetBIOS - any party able to reach a Jumis SQL Server can compute the password offline and authenticate. The ##Tilde_JumisAdmin## login is a member of the sysadmin server role. Successful authentication therefore grants full administrative control of the SQL Server instance and read/write access to every customer's accounting database hosted on it. The on-premise server installation also programmatically enables xp_cmdshell during routine operation, so sysadmin access escalates to operating-system command execution on the database server.

CVE-2026-97380
MariaDB server is a community developed fork of MySQL server. From 10.6.1 until 10.6.28, 10.11.19, 11.4.13, 11.8.9, 12.3.3, and 13.0.2, the GRANT PROXY statement treats an IDENTIFIED clause with an empty password as though authentication were not specified, causing it to check the wrong grantor privileges. A low-privileged attacker who can name another account can exploit this authorization error to set that account's password. This issue is fixed in versions 10.6.28, 10.11.19, 11.4.13, 11.8.9, 12.3.3, and 13.0.2.

CVE-2026-84731
An unauthenticated remote attacker can bypass authentication and gain full access to administrative API endpoints in Nutanix Prism Element by including a crafted internal management HTTP header. The vulnerability is caused by a misconfiguration in the application's authentication filters. Consequently, the server responds with a Set-Cookie header containing a valid JSESSIONID. This session cookie decodes to a JSON Web Token (JWT) granting maximum cluster administrative privileges. Successful exploitation allows the attacker to execute root-level commands on all Controller VMs (CVMs) in the cluster, leading to complete cluster destruction and unauthorized access to VM memory and virtual disks.

CVE-2026-123799
SuperTokens Core is an open source authentication server. From 11.0.0 until 11.0.9, 11.1.4, 11.2.4, 11.3.8, 11.4.8, 12.0.11, and 12.1.2, Dashboard.isValidUserSession treats any stored session row as valid without comparing DashboardSessionInfo.expiry to the current time. DashboardQueries.getSessionInfoWithSessionId also selects by app and session identifier without an expiry predicate, leaving the periodic DeleteExpiredDashboardSessions cleanup as the only expiration enforcement. An attacker who obtains a dashboard administrator session after its 30-day lifetime can continue using POST /recipe/dashboard/session/verify until the row is removed, and frequent Core restarts can prevent the 12-hour cleanup sweep from running. The stale session retains full dashboard read and write access, but the flaw does not provide a way to guess or acquire the random session identifier. This issue is fixed in versions 11.0.9, 11.1.4, 11.2.4, 11.3.8, 11.4.8, 12.0.11, and 12.1.2.
-
CVE-2026-109437
Cognition before 0.13.0 contains an unauthenticated remote code execution vulnerability due to defaulting its agent sandbox backend to local execution and shipping no authentication on its REST/SSE API. Attackers can create a session via POST /sessions and post a message via POST /sessions/{id}/messages without credentials, causing the Deep Agents ReAct loop to run attacker-directed shell commands through the local shell backend, resulting in remote code execution as the server process.

CVE-2026-70005
Weak authentication in Active Directory Federation Services (AD FS) allows an unauthorized attacker to bypass a security feature over a network.
-
CVE-2026-102748
Dgraph is an open source distributed GraphQL database. Prior to 25.4.0, Dgraph Zero registers administrative HTTP routes on port 6080 without authentication when the administrative interface is enabled. The /removeNode route accepts attacker-controlled id and group values and passes them to Server.RemoveNode, where group 0 can trigger ProposePeerRemoval. A remote unauthenticated attacker who can reach the Zero HTTP port can read topology through /state, allocate identifiers through /assign, access the exposed /moveTablet administrative route, or remove membership through /removeNode, disrupting the Zero control plane and destabilizing Alpha nodes that depend on Zero. The route registration occurs in dgraph/cmd/zero/run.go, and the demonstrated membership-removal path reaches Server.RemoveNode and ProposePeerRemoval. This issue is fixed in version 25.4.0.
-
CVE-2026-82116
Missing Authentication for Critical Function Vulnerability in HiRDB. This issue affects HiRDB Server Version 10: from 10-00 before 10-12-01; HiRDB Server Version 9: from 09-00 through 09-66-22; HiRDB Server with Additional Function Version 9: from 09-00 through 09-66/V; HiRDB Server Version 9(32): from 09-02 through 09-66-22; HiRDB Server with Additional Function Version 9(32): from 09-00 through 09-66-/V.
-
CVE-2026-53709
MCP Context Forge is an MCP gateway and administrative platform. Prior to 1.0.2, mcpgateway/config.py and .env.example ship a known JWT_SECRET_KEY, while verify_jwt_token() accepts HS256 tokens signed with that key and get_current_user() creates a platform administrator when the token subject matches PLATFORM_ADMIN_EMAIL and REQUIRE_USER_IN_DB is false. A remote unauthenticated attacker can therefore mint accepted administrator tokens without a database account. While the vulnerable signing key remains configured and the platform-admin bootstrap remains enabled, forged access survives password rotation, account deletion, and session revocation, allowing administrative disclosure, modification, and service disruption. This issue is fixed in version 1.0.2.
-
CVE-2026-77524
KEDA is a Kubernetes-based Event Driven Autoscaling component. In version 2.20.2 and earlier, a namespace administrator who can create TriggerAuthentication and ScaledObject resources can set hashiCorpVault.address to a tenant-controlled endpoint and select Kubernetes authentication without an explicit credential. KEDA then uses the operator pod's projected ServiceAccount token and sends it to that endpoint as a Vault login credential. The JWT-shape filter from the prior CVE-2025-68476 remediation accepts the operator token because its subject is a Kubernetes ServiceAccount, so the attacker can obtain the operator's cluster-wide permissions, including broad Secret reads and workload or admission-related operations. This vulnerability is fixed in 2.21.0.
-
