CVE-2026-7261SoapServer session-persisted object use-after-free via SOAP header fault

Updated under an hour ago ()

Does this affect you?

It affects PHP Group PHP and 1 other product. Add what you run to find out whether that includes you.

No exploitation reported and no EPSS estimate yet.

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.
