CVE-2026-75134
No known patch is available for this vulnerability.
The affected plugin has not been updated on WordPress.org since before this CVE was disclosed; the latest installable version is still vulnerable. If you have the affected software installed, you should uninstall or replace it rather than wait for an update.
Description
SEOWriting plugin for WordPress through 1.12.5 contains a stored cross-site scripting vulnerability that allows authenticated contributors to inject malicious JavaScript by exploiting an overly permissive KSES allowlist that explicitly permits the onload event handler on iframe elements. Attackers can store crafted JavaScript payloads in post content that execute when the affected post is viewed or previewed by higher-privileged users, potentially leading to privilege escalation or account compromise.
