CVE-2026-1780
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 · uneditedThe [CR]Paid Link Manager plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the URL path in all versions up to, and including, 0.5 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.
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 confidenceThe CR Paid Link Manager WordPress plugin versions up to 0.5 contains a reflected XSS vulnerability in URL path handling due to insufficient input sanitization and output escaping. Unauthenticated attackers can inject malicious JavaScript via crafted URLs that execute when users are tricked into clicking specially constructed links.

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 plugin installationIn WordPress admin, navigate to Plugins > Installed Plugins and look for 'CR Paid Link Manager'. Check if the plugin is active.Affected if The plugin is installed and active, making the vulnerable code reachable.
-
Check installed versionIn the plugins list, find the version number listed for CR Paid Link Manager. Compare it to the affected range: versions up to and including 0.5.Affected if The installed version is 0.5 or earlier.
-
Identify URL path reflection pointIdentify any frontend-facing page or endpoint that uses the plugin. Test by visiting a URL with a malicious path segment (e.g., /<script>alert(1)</script>/) and checking if the path is reflected in the HTML response without encoding.Affected if User-supplied URL path data appears in the page output unescaped, indicating the XSS sink is present and exploitable.
-
Confirm exploitability without authenticationAttempt the XSS payload described above while not logged in (logged out of WordPress). Observe if the script executes or is reflected in the response.Affected if The vulnerability is exploitable by unauthenticated users, meaning anyone can trigger the reflected XSS via crafted links.
A user is affected if the CR Paid Link Manager plugin is active at version 0.5 or earlier and URL path segments are reflected in HTTP responses without HTML escaping.

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 dataUpdate the plugin to a patched version once available; alternatively, deploy a WAF rule to filter malicious URL path patterns and warn users against clicking untrusted links.
