Package : php8.4 CVE ID : CVE-2026-7260 CVE-2026-17543 CVE-2026-17544 Debian Bug : 1143153

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, information disclosure or the execution of arbitrary code.

For the stable distribution (trixie), these problems have been fixed in version 8.4.24-1~deb13u1.

We recommend that you upgrade your php8.4 packages.
