CVE-2026-8702: CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in garber GBI To Print
The GBI To Print plugin for WordPress is vulnerable to Stored Cross-Site Scripting in version 1.0 via the 'div' attribute of the 'gbitoprint' shortcode. This is due to insufficient output escaping in the gbi_toprint_shortcode() function, which concatenates the raw shortcode attribute value directly into an HTML attribute without applying esc_attr() or any other sanitization. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
AI Analysis
Technical Summary
CVE-2026-8702 is a stored cross-site scripting vulnerability in the GBI To Print WordPress plugin version 1.0. The issue arises from insufficient output escaping in the gbi_toprint_shortcode() function, which directly inserts the raw 'div' shortcode attribute value into an HTML attribute without sanitization such as esc_attr(). Authenticated attackers with contributor-level privileges or higher can exploit this to inject arbitrary JavaScript that executes in the context of users viewing the compromised pages. This vulnerability is classified under CWE-79 and has a CVSS 3.1 base score of 6.4 (AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N). No patch or official fix has been disclosed by the vendor, and no known exploits have been reported.
Potential Impact
Successful exploitation allows an authenticated user with contributor or higher privileges to inject persistent malicious scripts into pages via the 'div' attribute of the shortcode. This can lead to partial confidentiality and integrity impacts (e.g., theft of user data or session tokens, content manipulation) but does not affect availability. The vulnerability affects the confidentiality and integrity of users interacting with the injected pages.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict contributor-level access to trusted users only and consider disabling or removing the GBI To Print plugin if feasible. Monitor for plugin updates from the vendor that address this vulnerability.
