The D-Link DIR-822A router version A_101 has a vulnerability in the tunnel_set_params function of the L2TP Control Message Parser component, leading to an out-of-bounds write. The attack can be launched remotely, and the exploit has been publicly disclosed.

The D-Link DIR-895L router version A1_102b07 has a vulnerability in the sendOffer/sendACK functions of the file udhcpcd/serverpacket.c in the udhcpcd component, causing a stack-based buffer overflow. The attack can only be performed within the local network, and the exploit has been published.

The @sap/cds-mtxs NPM library does not perform sufficient checks on certain functionality used in multitenant CAP applications with extensibility enabled. An unauthenticated attacker could send specially crafted requests to obtain sensitive credentials and abuse them to replace or delete tenant data. Successful exploitation can result in a high impact on availability and integrity of the application, and partial impact on confidentiality of business data.

SAP GUI for Java does not correctly enforce the trust level policy for certain functions invoked from a connected backend system. A low-privileged attacker could exploit this weakness by manipulating a connected backend system to trigger affected functionality. This could allow arbitrary command execution on the victim's machine, leading to a high impact on confidentiality, integrity, and availability.

SAP NetWeaver Message Server does not sufficiently validate the authenticity of internal application server components during registration. An unauthenticated attacker with network access could register an unauthorized component and potentially perform unauthorized actions, resulting in high impact on confidentiality, integrity, and availability.

A memory safety vulnerability exists in the Extended Passport Protocol (EPP) processing library. Under specific conditions, an unauthenticated attacker could exploit a crafted network request with a malformed EPP header, potentially resulting in undefined behavior and abnormal program termination. Successful exploitation may have high impact on confidentiality, integrity, and availability.

Vulnerability in knowns before version 0.30.0 serves the management API without authentication on all network interfaces by default, with no password required on fresh installations. Attackers can access the unauthenticated /api/tunnel/start endpoint to provision a public tunnel and republish the API at a publicly accessible address.

Vulnerability in knowns before 0.30.0 fails to validate import names in the import routes, allowing unauthenticated attackers to write files outside the imports directory. Attackers can supply traversal sequences in the name parameter to escape the imports directory and overwrite arbitrary files writable by the server process.

Adobe Commerce is affected by an Improper Neutralization of Special Elements Used in a Template Engine vulnerability that could result in arbitrary code execution in the context of the current user. An attacker could exploit this vulnerability to execute arbitrary code. Exploitation does not require user interaction. Scope is changed.

In JetBrains Hub before 2026.2.52442, an unauthenticated attacker could register a trusted service and gain superuser privileges.
