Title

PHP内存错误引用漏洞

Description

PHP是一种广泛用于Web开发的开源服务器端脚本语言。 PHP存在内存错误引用漏洞。该漏洞源于SoapServer在配置为SOAP_PERSISTENCE_SESSION时，处理SOAP请求出错后未能正确处理对象持久化，导致对象被释放后仍保留指向它的指针，攻击者可利用该漏洞触发内存错误引用，造成内存破坏、信息泄露或进程崩溃。

CVE-2026-7261 (GCVE-0-2026-7261)

Vulnerability from cvelistv5 – Published: 2026-05-10 04:07 – Updated: 2026-05-11 13:14

Title

SoapServer session-persisted object use-after-free via SOAP header fault

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 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.

Severity

6.3 (Medium)
