CVE-2017-10974
HighSummary
Yaws version 1.91 allows unauthenticated remote file disclosure via HTTP Directory Traversal using the /%5C../ sequence on port 8080.
Risk Assessment
The organization may be exposed to sensitive data disclosure, potentially leading to further attacks or privacy breaches.
Recommendation
It is recommended to update Yaws to the latest version and implement additional security mechanisms against Directory Traversal attacks.

A vulnerability was identified in Seetong T8108, T8108P, T8116 and T8232 version 4.6.1.4-build202604241011. The affected element is an unknown function of the Debug Service component, leading to improper authentication. The attack can be launched remotely and the exploit is publicly available.
- CVE-2026-101090Critical
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.
- CVE-2026-101084Critical
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.
- CVE-2026-101065Critical
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.
- CVE-2026-100740Critical
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)
Yaws 1.91 allows Unauthenticated Remote File Disclosure via HTTP Directory Traversal with /%5C../ to port 8080. NOTE: this CVE is only about use of an initial /%5C sequence to defeat traversal protection mechanisms; the initial /%5C sequence was apparently not discussed in earlier research on this product.
