CVE-2025-49148
HighSummary
ClipShare to lekkie, wieloplatformowe narzędzie do udostępniania schowka. W wersjach przed 3.8.5, serwer ClipShare dla systemu Windows korzysta z domyślnej kolejności wyszukiwania DLL, co pozwala lokalnemu użytkownikowi na wstrzyknięcie złośliwych bibliotek DLL, prowadząc do wykonania dowolnego kodu w kontekście serwera.
Risk Assessment
Podatność ta stwarza ryzyko wykonania złośliwego kodu przez lokalnych użytkowników, co może prowadzić do eskalacji uprawnień, jeśli serwer jest uruchamiany przez administratora lub innego użytkownika z podwyższonymi uprawnieniami.
Recommendation
Zaleca się aktualizację do wersji 3.8.5 lub nowszej, aby usunąć tę podatność oraz ograniczenie dostępu do folderu zawierającego clip_share.exe dla nieuprzywilejowanych użytkowników.

Nezha 2.2.3 contains a Host header injection regression in the OAuth2 redirect endpoint. When the dashboard_host setting is empty, /api/v1/oauth2/{provider} reflects the attacker-supplied Host header into the redirect_uri. An attacker can steal the victim's authorization code and take over the account.

Obot up to commit d7e6970, when started via the Docker quickstart from README, listens on 0.0.0.0:8080 with authentication disabled. Every request is mapped to a synthetic 'nobody' user with Owner and Admin roles, granting full administrative access. The quickstart also mounts /var/run/docker.sock, giving access to the host's Docker control surface.

- CVE-2026-100741Critical
Eval injection vulnerability in hMailServer (versions 6.0.0-6.3.3) allows a remote, unauthenticated attacker to execute arbitrary JScript in the service process with service account privileges. It requires non-default configuration: event scripting enabled, JScript as script language, and an OnClientValidatePassword handler defined. Exploitation uses a password with backslash and apostrophe that is not properly escaped.
- CVE-2026-100721Critical
A vulnerability in vm2 before 3.12.2 allows an authorization bypass in the NodeVM external-module resolver. When an embedder configures `require.external` with a custom resolver and `context: 'host'`, guest code can require an allowlisted module and then an absolute path of a non-allowlisted sibling sharing the resolved prefix. This leads to a sandbox escape and arbitrary code execution in the host process.

A vulnerability in D-Link DIR-895L A1_102b07 affects the tunnel_set_params function in tunnel.c of the L2TP Control Channel Parser component. Manipulation results in an out-of-bounds write. The attack can be initiated remotely, and the exploit is now public.
Original NVD description (English source)
ClipShare is a lightweight and cross-platform tool for clipboard sharing. Prior to 3.8.5, ClipShare Server for Windows uses the default Windows DLL search order and loads system libraries like CRYPTBASE.dll and WindowsCodecs.dll from its own directory before the system path. A local, non-privileged user who can write to the folder containing clip_share.exe can place malicious DLLs there, leading to arbitrary code execution in the context of the server, and, if launched by an Administrator (or another elevated user), it results in a reliable local privilege escalation. This vulnerability is fixed in 3.8.5.
