- CERT-EU says the PHP flaws could affect every version from 5 onward, and Cloudflare has pushed temporary firewall rules to all customers, including free accounts.
- Calif Research says paths dating to PHP 5.4.0 can yield pre-authentication RCE on WordPress, Drupal and Joomla until the PHP engine itself is updated.
- CVE-2026-87337 in Oracle Access Manager and several HPE Aruba AOS-8 and AOS-10 flaws scored CVSS 10 with no fixed build named, so track vendor updates next.
