Published Mar 13, 2026 CVSS 4.0 · 5.1 Medium EPSS < 1% KEV · Not listed

Description

Improper neutralization of input during web page generation ('cross-site scripting') vulnerability in OpenText™ Vertica allows Reflected XSS.
The vulnerability could lead to Reflected XSS attack of cross-site scripting in Vertica management console application.This issue affects Vertica: from 10.0 through 10.X, from 11.0 through 11.X, from 12.0 through 12.X, from 23.0 through 23.X, from 24.0 through 24.X, from 25.1.0 through 25.1.X, from 25.2.0 through 25.2.X, from 25.3.0 through 25.3.X.

Analysis

Technical impact

Improper neutralization of input during web page generation in the OpenText Vertica management console allows reflected cross‑site scripting. An attacker could inject malicious JavaScript that executes in the victim’s browser context, potentially leading to session hijacking, data theft, or unauthorized actions performed on behalf of the user. This vulnerability represents a typical reflected XSS weakness (CWE‑79).

Affected Systems

OpenText Vertica is affected from version 10.0 through 10.X, 11.0 through 11.X, 12.0 through 12.X, 23.0 through 23.X, 24.0 through 24.X, 25.1.0 through 25.1.X, 25.2.0 through 25.2.X, and 25.3.0 through 25.3.X.

Risk and Exploitability

The CVSS score of 5.1 indicates a moderately serious impact. An EPSS score of less than 1% shows a low likelihood of active exploitation, and the vulnerability is not listed in the CISA KEV catalog. Because the attack surface is a web interface, the likely vector is a victim clicking a crafted link or visiting a malicious site that triggers the reflected payload. Exploitation requires user interaction and does not need elevated privileges within the Vertica environment.

Affected Products

Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).
