Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2026-2328 is a vulnerability caused by insufficient input validation, enabling path traversal attacks that allow access to backend components beyond their intended scope and resulting in the exposure of sensitive information. Published on 2026-03-30, it is associated with CWE-790 and carries a CVSS v3.1 base score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N), indicating high severity primarily due to confidentiality impact.

An unauthenticated remote attacker can exploit this vulnerability over the network with low attack complexity and no user interaction required. Successful exploitation grants access to sensitive information without privileges, scope changes, or disruption to integrity or availability.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

Input validation directly requires checking and filtering special elements in data received from upstream before further processing or forwarding.

Output filtering validates data sent downstream and can catch or correct unfiltered special elements prior to transmission.

PR.PS-06 mostly match
prevents

Secure SDLC practices directly require proper sanitization and filtering of special elements before data passes downstream.

ID.RA-01 partial match
prevents

Identifying recorded vulnerabilities can surface missing input filters during code or configuration review.

finds

Security testing can detect improper filtering but does not itself implement the filtering control.

prevents

Secure development life cycle mandates input validation and sanitization that directly prevents improper filtering of special elements.

prevents

Application security requirements explicitly call for input validation controls that mitigate improper special-element filtering.

prevents

Secure system architecture and engineering principles include defensive input handling that reduces the risk of unfiltered special elements.

prevents

Secure coding standards require proper filtering and encoding of special elements before downstream processing.
