NVD · unedited
URL Redirection to Untrusted Site ('Open Redirect') vulnerability in Pexle Chris Library Viewer.This issue affects Library Viewer: from n/a through 2.0.6.

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 · high confidence

An open redirect vulnerability in Pexle Chris Library Viewer versions up to 2.0.6 allows attackers to craft malicious URLs that redirect users to arbitrary external sites by manipulating the application's redirect parameters. This can be exploited for phishing attacks or to bypass trust boundaries.

MitigationImplement strict allowlist-based URL validation for redirect parameters, or replace direct URL input with indirect references (e.g., validated URL mappings) to prevent arbitrary redirection.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify installed version of Pexlechris Library Viewer
    Check the application's version number in its 'About' section, configuration files, or the application metadata (e.g., manifest, package info). Look for a version field or build number.
    Affected if The installed version is 2.0.6 or earlier, or any version below 2.0.6.1.
  2. Locate the application's redirect functionality
    Search the application configuration or code for redirect-related parameters (e.g., 'redirect', 'url', 'next', 'return', 'destination'). Check if URL redirection endpoints exist.
    Affected if Redirect functionality with user-controllable parameters is present and accessible.
  3. Test redirect parameter for arbitrary URL acceptance
    If redirect parameters are found, construct a test URL with an external domain (e.g., '?redirect=https://example.com') and observe if the application allows navigation to the arbitrary URL without validation.
    Affected if The redirect parameter accepts and follows arbitrary URLs without allowlist validation or indirect reference mapping.
  4. Check for URL validation implementation
    Inspect the application's redirect handling code or configuration for any allowlist logic, domain validation, or indirect reference mapping that restricts allowed redirect targets.
    Affected if No allowlist-based validation, domain filtering, or indirect reference system is implemented for redirect parameters.

You are affected if your Pexlechris Library Viewer version is below 2.0.6.1 AND the application exposes redirect functionality that accepts arbitrary URLs without strict validation.
