Overview

CVE-2026-10827 is a low-severity vulnerability. It was published on August 1, 2026 and has a CVSS 3.1 base score of 3.5 (LOW).

This vulnerability has a CVSS 3.1 base score of 3.5, rated LOW. It can be exploited remotely over the network. Some level of privileges is required for exploitation.

Technical description

The Spectra Legacy WordPress plugin before 2.20.0 does not validate or escape several block style attributes before using them to build the CSS it outputs on the front end, allowing users with the Contributor role and above to inject arbitrary CSS into the pages that render the affected block. The injected styles are served to anonymous visitors of those pages and can force external resource loads, deface/redress the page, or exfiltrate data via CSS attribute selectors. JavaScript execution is not possible at this role (the script-tag breakout is removed by KSES), so the impact is limited to CSS injection.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
