Multiple Vulnerabilities Discovered in PHP, Prompting Urgent Security Updates
The PHP project has recently released a security advisory, addressing several vulnerabilities affecting various versions of PHP. These vulnerabilities range from potential log tampering to arbitrary file inclusion and data integrity violations. It is strongly recommended that all PHP users update their systems to the latest patched versions immediately.
Key Vulnerabilities and Their Impact
CVE-2024-9026: Log Tampering in PHP-FPM
