CVE-2026-27503

SVXportal <= 2.5 admin/log.php Search Reflected XSS

Published Feb 20, 2026 CVSS 4.0 · 5.1 Medium EPSS < 1% KEV · Not listed
Description
SVXportal version 2.5 and prior contain a reflected cross-site scripting vulnerability in admin/log.php via the search query parameter. When an authenticated administrator views a crafted URL, the application embeds the unsanitized parameter value directly into an HTML input value attribute, allowing attacker-supplied JavaScript to execute in the administrator's browser. This can enable session theft, administrative action forgery, or other browser-based compromise in the context of an admin user.

Analysis

AI-generated

Technical impact

SVXportal versions 2.5 and earlier allow a reflected cross‑site scripting flaw in the admin/log.php endpoint. An authenticated administrator who opens a maliciously crafted URL containing an unsanitized search parameter can inject JavaScript that executes in the attacker’s context. This can lead to session theft, forgery of administrative actions, and broader browser‑based compromise. The weakness is classified as CWE‑79.

Affected Systems

The affected product is SVXportal, supplied by the vendor sa2blv, and includes all releases up to and including version 2.5. No patch has been issued at the time of this assessment, and users are advised to verify whether newer releases incorporate a fix.

Risk and Exploitability

The CVSS score of 5.1 indicates moderate severity, while the EPSS rating of less than 1 % reflects a very low current exploitation probability. The vulnerability is not listed in CISA’s KEV catalog. Compromise requires an authenticated administrator with web UI access; an attacker must craft a URL, lure an admin to click, and provide the malicious payload. Although the exploitation path is straightforward, the realistic risk remains modest under current conditions.

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • Upgrade to the latest SVXportal release when it incorporates a fix for the reflected XSS in admin/log.php
  • Ensure that user‑supplied search parameters are strictly validated and properly escaped before rendering in any HTML output
  • Implement a Content Security Policy that restricts inline script execution and limits data‑origin loading to mitigate accidental XSS exploitation
