Amazon Linux 2 : php, --advisory ALAS2PHP8.2-2026-013 (ALASPHP8.2-2026-013)
critical Nessus Plugin ID 332033
Synopsis
The remote Amazon Linux 2 host is missing a security update.Description
The version of php installed on the remote host is prior to 8.2.33-1. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2PHP8.2-2026-013 advisory.Improper escaping of backslashes in attacker-provided parameters would allow for trivial SQL injection in PHP versions from 8.2.* before 8.2.33, from 8.3.* before 8.3.33, from 8.4.* before 8.4.24, and from 8.5.* before 8.5.9. (CVE-2026-17543)
Circular symbolic links in phar archives could lead to unbounded recursion, exhausting the C stack and crashing the PHP process, in PHP versions from 8.2.* before 8.2.33, from 8.3.* before 8.3.33, from 8.4.* before 8.4.24, and from 8.5.* before 8.5.9. (CVE-2026-7260)
