CVE-2026-6735 (GCVE-0-2026-6735)

Vulnerability from cvelistv5 – Published: 2026-05-10 03:27 – Updated: 2026-05-11 13:25

Title

XSS within PHP-FPM status endpoint

Summary

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.

Severity

7.3 (High)

CVE-2026-7258 (GCVE-0-2026-7258)

Vulnerability from cvelistv5 – Published: 2026-05-10 04:28 – Updated: 2026-05-11 13:06

Title

Out-of-bounds read in urldecode() on NetBSD

Summary

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 (like isxdigit()). 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, which can trigger a denial of service.

Severity

6.3 (Medium)

CVE-2026-7259 (GCVE-0-2026-7259)

Vulnerability from cvelistv5 – Published: 2026-05-10 04:13 – Updated: 2026-05-11 13:13

Title

Null pointer dereference in php_mb_check_encoding() via mb_ereg_search_init()

Summary

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, a mismatch between encoding lists in Oniguruma and mbfl leads to a NULL pointer dereference, resulting in a segmentation fault and denial of service. The vulnerability is exploitable when user-controlled input can influence the encoding passed to mb_regex_encoding().

Severity

2.1 (Low)

CVE-2026-7262 (GCVE-0-2026-7262)

Vulnerability from cvelistv5 – Published: 2026-05-10 04:00 – Updated: 2026-05-11 13:14

Title

NULL pointer dereference in SOAP apache:Map decoder with missing <value>

Summary

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 to dereferences 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.

Severity

2.9 (Low)

CVE-2026-7568 (GCVE-0-2026-7568)

Vulnerability from cvelistv5 – Published: 2026-05-10 03:42 – Updated: 2026-05-11 13:25

Title

Signed integer overflow in metaphone()

Summary

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.

Severity

6.3 (Medium)
