"The version of PHP installed on the remote host is prior to 8.4.24. It is, therefore, affected by multiple
vulnerabilities as referenced in the Version 8.4.24 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)

  - Attacker-provided inputs to bccomp() could lead to an out-of-bounds write with stack and heap corruption
    in PHP versions from 8.4.* before 8.4.24 and from 8.5.* before 8.5.9. (CVE-2026-17544)

  - 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)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
