A flaw was found in the Node.js DNS resolver APIs. Hostnames passed to dns.resolve that contain an embedded NUL character can be truncated when processed by c-ares. An attacker who can supply such a name may cause the application to resolve and act on an unintended hostname.

Threats
Impact
Important
A flaw was found in the Node.js TLS stack. Improper normalization of hostnames that use fullwidth Unicode digits to represent an IPv4 address can cause certificate hostname verification to accept a certificate that does not identify the intended peer. This may allow an attacker who can influence the connection target to impersonate a TLS server.

Attack Complexity is High because the NUL-bearing name must reach those APIs and the application must rely on the returned records (for example to open a subsequent connection). Successful abuse can redirect trust in name resolution and lead to confidentiality and integrity impact comparable to connecting to the wrong host; Availability is not directly affected.

"text": "This issue is rated Important. Exploitation requires a Node.js TLS client to connect using a hostname that contains fullwidth Unicode digits which normalize to an IPv4 address, together with a certificate that satisfies the incorrect matching behavior. Attack Complexity is High because the attacker must influence the host string used for the connection (for example a user-supplied URL) and present a suitable certificate, typically with a privileged network position relative to that connection. Confidentiality and Integrity are High because a successful bypass enables server impersonation and exposure or alteration of TLS application data; Availability is not affected. This flaw affects Node.js 24.x and 26.x lines and does not affect the 22.x line per the upstream advisory.",

Drag nodes to arrange them. Double-click a related vulnerability to open it, or a source to visit its link. The Physics button on the left tunes the layout and the simulation; the legend at the bottom left hides or shows nodes by kind and by sighting type.
Experimental. This forecast is provided for visualization only and may change without notice. Do not use it for operational decisions.
Forecast uses a logistic model when the trend is rising, or an exponential decay model when the trend is falling. Fitted via linearized least squares.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
