    PHP is an HTML-embedded scripting language. PHP attempts to make it easy for developers to write     dynamically generated web pages. PHP also offers built-in database integration for several commercial and     non-commercial database management systems, so writing a database-enabled webpage with PHP is fairly     simple. The most common use of PHP coding is probably as a replacement for CGI scripts.

Tenable has extracted the preceding description block directly from the Fedora security advisory.

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

According to its self-reported version number, the version of PHP installed on the remote host is 8.2.x prior to 8.2.33, 8.3.x prior to 8.3.33, 8.4.x prior to 8.4.24, or 8.5.x prior to 8.5.9. It is, therefore, affected by multiple vulnerabilities:

- Out-of-bounds write in bccomp() in BCMath. (CVE-2026-17544)

- Vulnerability in the bundled libgd library. (CVE-2026-9672)

- SQL injection via E'...' backslash breakout in PGSQL. (CVE-2026-17543)

- Crash via recursive symlinks in Phar. (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.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - 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)

Note that Nessus relies on the presence of the package as reported by the vendor.

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.

The version of PHP installed on the remote host is prior to 8.5.9. It is, therefore, affected by multiple vulnerabilities as referenced in the Version 8.5.9 advisory.
