CVE-2026-7262 Unknown Vendor CVE debrief

Who should care

Teams running exposed PHP SOAP services, especially those that use typemap configuration, should treat this as an availability risk. Administrators of PHP 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 should prioritize remediation.

Technical summary

The issue affects SOAP server decoding when a typemap is configured and a value element is missing. The code path checks the wrong variable, which can leave a NULL pointer dereferenced and cause a segmentation fault. The disclosed impact is limited to process crash / denial of service, with no integrity or confidentiality impact described in the supplied record.

Defensive priority

Low severity overall, but prioritize quickly if the affected PHP SOAP service is internet-facing or customer-critical because the impact is a remote unauthenticated crash.

Recommended defensive actions

• Upgrade PHP to a fixed release: 8.2.31, 8.3.31, 8.4.21, or 8.5.6, or later.
• Inventory PHP SOAP servers and confirm whether typemap configuration is in use.
• Treat unexpected PHP-FPM, Apache module, or application process crashes as a security signal and review logs around SOAP requests.
• If immediate upgrading is not possible, reduce exposure of SOAP endpoints with network controls and authentication at the perimeter where feasible.
