Security Summary

CVE-2025-26541 is an Improper Neutralization of Input During Web Page Generation vulnerability, classified as Reflected Cross-site Scripting (XSS) under CWE-79, affecting the CodeSolz Bitcoin / AltCoin Payment Gateway for WooCommerce plugin (woo-altcoin-payment-gateway). This issue impacts all versions from n/a through 1.7.6 and was published on 2025-03-26 with a CVSS v3.1 base score of 7.1 (AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:L).

An unauthenticated attacker with network access can exploit this vulnerability by crafting a malicious payload that reflects off the web page, requiring user interaction such as clicking a specially crafted link. Exploitation changes the scope (S:C), enabling the payload to execute in the context of the targeted user's browser session, with low impacts on confidentiality, integrity, and availability (C:L/I:L/A:L). Potential outcomes include theft of session cookies, keystroke logging, or phishing attacks against site administrators or users.
