CVE-2017-5652
HighSummary
In Apache Impala (versions 2.7.0 to 2.8.0), a vulnerability was identified where one of the ports sent data in plaintext even when the cluster was configured to use TLS. The StatestoreSubscriber class did not use the appropriate secure Thrift transport, allowing eavesdropping on data by third parties.
Risk Assessment
The organization is at risk of exposing sensitive data, as an attacker with network access could intercept data transmitted through the vulnerable port.
Recommendation
It is recommended to upgrade Apache Impala to the latest version and configure all ports to use secure Thrift transport to ensure data protection.

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.

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)
During a routine security analysis, it was found that one of the ports in Apache Impala (incubating) 2.7.0 to 2.8.0 sent data in plaintext even when the cluster was configured to use TLS. The port in question was used by the StatestoreSubscriber class which did not use the appropriate secure Thrift transport when TLS was turned on. It was therefore possible for an adversary, with access to the network, to eavesdrop on the packets going to and coming from that port and view the data in plaintext.
