Uncertainty and limitations

Read the evidence limits before acting on this record.

Exact comment/wpautop trigger path and which backported trains are fully fixed should be confirmed against the WordPress 7.1.1 release notes for your installed major.

  • Not every WordPress site is on the 7.1 train — confirm your major and apply the matching security release.
  • WAF rules are not a substitute for the core upgrade.
  • This campaign tracks the core XSS issue, not unrelated plugin XSS in the same news cycle.
