CVE-2026-1295 is a stored cross-site scripting vulnerability in the Buy Now Plus – Payments with Stripe plugin for WordPress. The flaw exists in the handling of the 'buynowplus' shortcode attributes, where input is not properly sanitized or escaped before being rendered on web pages. This allows authenticated users with Contributor-level permissions or higher to inject arbitrary JavaScript code that executes in the context of other users viewing the page. The vulnerability affects all versions up to and including 1.0.2. The CVSS 3.1 base score is 6.4, reflecting network attack vector, low attack complexity, required privileges at the contributor level, no user interaction, and impacts on confidentiality and integrity but not availability.

An attacker with Contributor-level access or above can inject persistent malicious scripts into pages using the vulnerable shortcode. These scripts execute in the browsers of users who visit the infected pages, potentially allowing theft of session cookies, defacement, or other malicious actions affecting confidentiality and integrity of user data. There is no indication of availability impact. No known exploits are reported in the wild at this time.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict Contributor-level access to trusted users only and consider removing or disabling the 'buynowplus' shortcode usage. Monitor for plugin updates from the vendor addressing this vulnerability.
