CVE-2025-49140
HighSummary
Pion Interceptor to framework do budowy oprogramowania komunikacyjnego RTP/RTCP. W wersjach od v0.1.36 do v0.1.38 występuje błąd w fabryce pakietów RTP, który może być wykorzystany do wywołania paniki w oparciu o SFU Pion za pomocą spreparowanych pakietów RTP.
Risk Assessment
Użytkownicy korzystający z pion/interceptor są narażeni na ryzyko awarii systemu, co może prowadzić do przerwy w działaniu usług komunikacyjnych.
Recommendation
Zaleca się aktualizację do wersji v0.1.39 lub nowszej, która weryfikuje długość paddingu, aby uniknąć paniki. Jeśli aktualizacja nie jest możliwa, należy ręcznie zastosować poprawkę lub odrzucić pakiety z ustawionym bitem P, gdy długość paddingu jest zerowa lub większa niż pozostała długość ładunku.

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 versions before v0.21.1 fail to enforce Access Control Rules on the /mcp-connect endpoint, allowing any authenticated user to connect to restricted MCP servers if they possess the server ID. Attackers can bypass authorization to access sensitive backend systems.

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)
Pion Interceptor is a framework for building RTP/RTCP communication software. Versions v0.1.36 through v0.1.38 contain a bug in a RTP packet factory that can be exploited to trigger a panic with Pion based SFU via crafted RTP packets, This only affect users that use pion/interceptor. Users should upgrade to v0.1.39 or later, which validates that: `padLen > 0 && padLen <= payloadLength` and return error on overflow, avoiding panic. If upgrading is not possible, apply the patch from the pull request manually or drop packets whose P-bit is set but whose padLen is zero or larger than the remaining payload.
