Deeper analysis
CVE-2025-28855 is a reflected cross-site scripting vulnerability arising from improper neutralization of input during web page generation. It affects the Teleport plugin for WordPress, developed by srcoley, in all versions through 1.2.4. The flaw is tracked under CWE-79 and carries a CVSS 3.1 score of 7.1.
An unauthenticated remote attacker can supply a crafted URL that triggers script execution in a victim's browser when the link is visited. Because the attack requires user interaction and results in changed scope, successful exploitation can allow limited impacts to confidentiality, integrity, and availability within the affected WordPress site.
The issue is documented in the Patchstack vulnerability database, which identifies the affected plugin versions and provides the canonical advisory entry for this CVE. The associated EPSS score remains low, with a current value of 0.0067 and a recorded peak of 0.0111.

Why these techniques?
Reflected XSS in a public-facing WordPress plugin allows an attacker to craft a malicious link that, when visited by a user, injects and executes arbitrary scripts in the browser context. This directly matches Drive-by Compromise (T1189), where victims are tricked into visiting a site that delivers malicious client-side code.
