CVE-2025-8051
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 · uneditedPath Traversal vulnerability in opentext Flipper allows Absolute Path Traversal. The vulnerability could allow a user to access files hosted on the server. This issue affects Flipper: 3.1.2.
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 confidencePath traversal vulnerability in OpenText Flipper 3.1.2 allows attackers to access files on the server filesystem using absolute path references. This occurs due to insufficient validation of user-supplied file path inputs, enabling unauthorized file disclosure beyond the intended web root directory.

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.
-
Verify OpenText Flipper installation versionLocate the Flipper installation directory and check the version manifest,About file, or application metadata. Common locations include the installation root folder or within the application properties.Affected if The installed version is exactly 3.1.2
-
Identify file handling endpointsReview application URLs and API endpoints for file-related functionality such as file download, file preview, file retrieval, or attachment serving endpoints.Affected if File retrieval or display endpoints accept a file path parameter and are accessible without authentication
-
Test for absolute path acceptanceSubmit a request to the identified file handling endpoint using an absolute path such as '/etc/passwd' (Linux) or 'C:\Windows\win.ini' (Windows) as the file parameter value.Affected if The application accepts and processes absolute path inputs without rejecting or sanitizing them
-
Check input validation behaviorObserve how the application handles path traversal sequences like '../' and absolute paths in file-related parameters. Compare responses against expected valid file requests.Affected if The application returns files outside the intended web root directory when absolute paths are provided
A user is affected if OpenText Flipper version 3.1.2 is installed AND file handling endpoints that accept path parameters are accessible, allowing retrieval of files via absolute path references.

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 strict input validation and path canonicalization to ensure all file path requests resolve within allowed directories. Sanitize or reject path traversal sequences and absolute path inputs, using allowlist validation where possible.
