CVE-2026-91862: CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in jetmonsters Getwid – Gutenberg Blocks

CVE-2026-91862 describes a stored cross-site scripting vulnerability in the Getwid – Gutenberg Blocks plugin for WordPress. The issue arises from insufficient input sanitization and output escaping of the 'data-image-points' parameter. Authenticated attackers with contributor-level privileges or higher can inject arbitrary web scripts into pages, which execute when those pages are accessed by other users. This vulnerability affects all versions from 0 up to and including 3.0.1.

An attacker with contributor-level access or higher can inject malicious scripts that execute in the context of other users viewing the compromised pages. This can lead to information disclosure and limited integrity impact. The vulnerability does not affect availability. The CVSS 3.1 base score is 6.4 (medium severity), reflecting network attack vector, low attack complexity, privileges required, no user interaction, and partial confidentiality and integrity impact.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or patch links are provided in the available data. Until a patch is available, restrict contributor-level access to trusted users only and consider disabling or limiting use of the affected plugin. Monitor vendor channels for updates and apply official patches promptly once released.
