CVE-2026-6735

A flaw was found in PHP, specifically within the PHP-FPM status page. Due to improper sanitation of user data, a remote attacker can craft a malicious URL. When a user views the PHP-FPM status page with this crafted URL, it can lead to the execution of arbitrary JavaScript code (Cross-Site Scripting or XSS) on their machine, potentially compromising their browser session or leading to further attacks.

CVE-2026-7258

A flaw was found in PHP. Some functions, including `urldecode()`, incorrectly pass signed characters to character type (ctype) functions. On certain systems, this can lead to accessing memory with a negative offset. This vulnerability can be exploited by an attacker to trigger a denial of service (DoS), making the affected PHP application or system unavailable.
