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

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2026-1728 advisory.

    In PHP versions 8.2.* before 8.2.31, 8.3.* before 8.3.31, 8.4.* before 8.4.21, and 8.5.* before 8.5.6, the     SOAP extension's object deduplication mechanism stores pointers to PHP objects in a global map without     incrementing their reference counts. When an apache:Map node contains duplicate keys, processing the     second entry overwrites the first in the temporary result map, freeing the original PHP object while its     stale pointer remains in the map. A subsequent href reference to the freed node can copy the dangling     pointer into the result. As PHP string allocations can reclaim the freed memory region, an attacker with     control over the SOAP request body can exploit this use-after-free to achieve remote code execution.
    (CVE-2026-6722)

    In PHP versions 8.2.* before 8.2.31, 8.3.* before 8.3.31, 8.4.* before 8.4.21, 8.5.* before 8.5.6, due to     improper sanitation of user data, it allows an attacker to compose an URL, which will cause the target to     execute arbitrary JavaScript code (XSS) on the target's machine when the target is viewing the PHP-FPM     status page. (CVE-2026-6735)

    Out-of-bounds read in urldecode() (CVE-2026-7258)

    Null pointer dereference in php_mb_check_encoding() via mb_ereg_search_init() (CVE-2026-7259)

    In PHP versions 8.2.* before 8.2.31, 8.3.* before 8.3.31, 8.4.* before 8.4.21, and 8.5.* before 8.5.6,     when SoapServer is configured with SOAP_PERSISTENCE_SESSION, the handler object is persisted across     requests via session storage. However, in the case SOAP requests results in an error, the persistance is     handled incorrectly, resulting in freeing the object while keeping a pointer to it, which may lead to use-     after-free. This may lead to memory corruption, information disclosure, or process crashes, with     confidentiality, integrity, and availability impact on the vulnerable system. (CVE-2026-7261)

The remote Alibaba Cloud Linux 3 host has packages installed that are affected by multiple vulnerabilities as referenced in the ALINUX3-SA-2026:0181 advisory.

    Package updates are available for Alibaba Cloud Linux 3 that fix the following vulnerabilities:

    CVE-2026-6722:
    In PHP versions 8.2.* before 8.2.31, 8.3.* before 8.3.31, 8.4.* before 8.4.21, and 8.5.* before 8.5.6, the     SOAP extension's object deduplication mechanism stores pointers to PHP objects in a global mapwithout     incrementing their reference counts. When an apache:Map node contains duplicate keys, processing the     second entry overwrites the first in the temporary result map, freeing the original PHP object while its     stale pointer remains in the map. A subsequent href reference to the freed node can copy the dangling     pointer into the result. As PHP string allocations can reclaim the freed memory region, an attacker with     control over the SOAP request body can exploit this use-after-free to achieve remote code execution.

    CVE-2026-6735:
    In PHP versions 8.2.* before 8.2.31, 8.3.* before 8.3.31, 8.4.* before 8.4.21, 8.5.* before 8.5.6, due to     improper sanitation of user data, itallows an attacker to compose an URL, which will cause the target to     execute arbitrary JavaScript code (XSS) on the target's machine when the target is viewing thePHP-FPM     status page.

    CVE-2026-7258:
    In PHP versions 8.2.* before 8.2.31, 8.3.* before 8.3.31, 8.4.* before 8.4.21, and 8.5.* before 8.5.6,     some functions, including urldecode(), pass signed char to ctype functions (likeisxdigit()). On the     systems with default signed char and optimized table-lookup ctype functions - such as NetBSD - this can     lead to accessing array with negative offset, whichcan trigger a denial of service.

    CVE-2026-7261:
    In PHP versions 8.2.* before 8.2.31, 8.3.* before 8.3.31, 8.4.* before 8.4.21, and 8.5.* before 8.5.6,     when SoapServer is configured with SOAP_PERSISTENCE_SESSION, the handler object is persisted across     requests via session storage. However, in the case SOAP requests results in an error, the persistance is     handled incorrectly, resulting in freeing the object while keeping a pointer to it, which may lead to use-     after-free. This may lead to memory corruption, information disclosure, or process crashes, with     confidentiality, integrity, and availability impact on the vulnerable system.

    CVE-2026-7262:
    In PHP versions 8.2.* before 8.2.31, 8.3.* before 8.3.31, 8.4.* before 8.4.21, and 8.5.* before 8.5.6,     when a SOAP server has a typemap configured, the decoding process contains a mistake which checks the     wrong variable in case of missing value element. This leads todereferences a NULL pointer, causing a     segmentation fault. This allows a remote unauthenticated attacker to crash the PHP SOAP server process,     resulting in denial of service.

    CVE-2026-7568:
    In PHP versions 8.2.* before 8.2.31, 8.3.* before 8.3.31, 8.4.* before 8.4.21, and 8.5.* before 8.5.6, the     metaphone() function in ext/standard/metaphone.c uses a signed int variable to track the current position     within the input string. If a string longer than 2,147,483,647 bytes is passed, a signed integer overflow     occurs, resulting in undefined behavior. This can lead to an out-of-bounds read, causing a segmentation     fault or access to unrelated memory, and may affect the availability of the PHP process.
