CERT-FR published an advisory covering multiple vulnerabilities in WordPress affecting versions prior to 7.1.1. The flaws could allow an attacker to compromise data confidentiality, perform indirect remote code injection (cross-site scripting), and bypass security policy protections. No specific exploitation details, proof-of-concept code, or CVE identifiers were included in the advisory text.
There is no indication in the bulletin that these vulnerabilities are being exploited in the wild. WordPress addressed the issues in its 7.1.1 maintenance and security release, published on 17 September 2026. Defenders running WordPress installations should update to version 7.1.1 or later as the primary mitigation, per the vendor's security bulletin.
