Summary

The SEOWriting plugin for WordPress through version 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.

Risk Assessment

An authenticated attacker with low privileges can execute scripts in the context of an administrator's browser, potentially leading to privilege escalation, session theft, or account takeover.

Recommendation

Update the SEOWriting plugin to the latest available version if one exists. Restrict contributor permissions and regularly review content for malicious code.
