CVE-2026-111410: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in E2Pdf.com e2pdf

The vulnerability identified as CVE-2026-111410 affects the E2Pdf.com e2pdf plugin through version 1.32.57. It is a stored cross-site scripting (XSS) flaw caused by improper neutralization of input during web page generation. This allows an attacker with at least low privileges and requiring user interaction to inject malicious scripts that can affect confidentiality, integrity, and availability to a limited extent. The CVSS 3.1 vector indicates network attack vector, low attack complexity, low privileges required, user interaction required, and scope change with low impact on confidentiality, integrity, and availability.

Successful exploitation of this stored XSS vulnerability can allow an attacker to execute arbitrary scripts in the context of the affected web application, potentially leading to information disclosure, modification of data, or disruption of service. The impact is rated medium based on the CVSS score and vector, reflecting limited but non-negligible risk to confidentiality, integrity, and availability.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, users should apply standard XSS mitigations such as input validation and output encoding where possible. Monitor vendor communications for updates on patches or official fixes.
