CVE-2026-2342
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedImproper neutralization of input during web page generation ('cross-site scripting') vulnerability in OceanicSoft Informatics Systems Ltd. ValeApp allows Stored XSS. This issue affects ValeApp: through 09072026. NOTE: The vendor was contacted early about this disclosure but did not respond in any way.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceA stored cross-site scripting (XSS) vulnerability exists in ValeApp by OceanicSoft Informatics Systems Ltd. due to improper neutralization of user-supplied input during web page generation. Attackers can inject malicious scripts that persist in the application and execute in victims' browsers when the contaminated data is rendered.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify ValeApp installation and versionLocate the ValeApp installation directory or check the application startup/version information (commonly found in an 'about' page, version file, or application headers). Compare your installed version to any official version releases from OceanicSoft Informatics Systems Ltd.Affected if The installed version of ValeApp is unpatched and matches the vulnerable release.
-
Locate user input fields that store dataIdentify all forms, input fields, and API endpoints in ValeApp that accept and store user-supplied data (such as user profiles, comments, settings, or custom fields). These are potential injection points for stored XSS.Affected if The application accepts user input and stores it for later display without sanitization.
-
Examine data storage mechanismsInspect the application's database or data storage to confirm that user-supplied input is persisted (rather than processed and discarded). Check database tables that hold user-generated content.Affected if User input is persisted in storage and can be retrieved for later rendering.
-
Review output rendering of stored dataTest how the application renders stored user data back to the browser by submitting a benign test payload (such as <script>alert('test')</script>) in an input field, then viewing that data in a different context or as a different user.Affected if The test payload executes as JavaScript in the browser when the stored data is displayed, indicating the vulnerability is present.
-
Verify authentication requirements for injectionDetermine what authentication or authorization level is required to submit the malicious input. Check if public users, authenticated users, or administrators can inject and persist scripts.Affected if Any authenticated or unauthenticated user can inject and persist scripts that execute in other users' browsers.
You are affected if ValeApp is installed and any user-supplied input is stored and rendered back to browsers without proper sanitization, allowing injected scripts to execute persistently.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement robust input validation and context-aware output encoding for all user-supplied data before rendering. Deploy Content Security Policy (CSP) headers and consider implementing a web application firewall as an additional layer of defense.
