Latest vulnerability

CVE-2026-10827: Spectra Legacy block styles let Contributors inject arbitrary CSS

Spectra Legacy before 2.20.0 uses several Contributor-controlled block style attributes to construct front-end CSS without adequate validation or escaping. A Contributor-or-higher user can store arbitrary CSS that is served to anonymous visitors of the affected page, enabling defacement, interface redressing, forced external resource loads and limited data exfiltration through attribute selectors. WordPress KSES removes the script-tag breakout at this role, so the published record does not establish JavaScript execution; it also does not disclose the affected block attributes or CSS builder.
