CVE-2026-7261

Name of the Vulnerable Software and Affected Versions PHP versions 8.2.0 through 8.2.30 PHP versions 8.3.0 through 8.3.30 PHP versions 8.4.0 through 8.4.20 PHP versions 8.5.0 through 8.5.5

Description When SoapServer is configured with SOAP PERSISTENCE SESSION, the handler object is persisted across requests using session storage. If a SOAP request results in an error, the persistence is handled incorrectly, causing the object to be freed while a pointer to it remains. This leads to a use-after-free condition, which is a situation where a program continues to use a pointer after it has been freed, potentially resulting in memory corruption, information disclosure, or process crashes.

Recommendations Update PHP version 8.2.x to 8.2.31 Update PHP version 8.3.x to 8.3.31 Update PHP version 8.4.x to 8.4.21 Update PHP version 8.5.x to 8.5.6
