Package : php8.4 CVE ID : CVE-2025-14179 CVE-2026-6104 CVE-2026-6722 CVE-2026-6735 CVE-2026-7258 CVE-2026-7259 CVE-2026-7261 CVE-2026-7262 CVE-2026-7263 CVE-2026-7568

Multiple security issues were found in PHP, a widely-used open source general purpose scripting language which could result in denial of service, SQL injection, cross-site scripting, information disclosure or the execution of arbitrary code.

For the stable distribution (trixie), these problems have been fixed in version 8.4.21-1~deb13u1.

We recommend that you upgrade your php8.4 packages.

For the detailed security status of php8.4 please refer to its security tracker page at:
https://security-tracker.debian.org/tracker/php8.4
