CVE-2026-7262: NULL pointer dereference in SOAP apache:Map decoder with missing <value>

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.

Security readout for executives and security teams

Plain-English summary

CVE-2026-7262 can let an unauthenticated remote attacker crash a PHP SOAP server when a vulnerable PHP version processes certain SOAP data with a typemap configured. The impact is service availability, not data theft or code execution based on the provided sources.

Executive priority

Treat as high priority for public SOAP services because exploitation can cause outage without credentials. Prioritize patching exposed services first, then internal services with business-critical availability requirements.

Technical view

Affected PHP SOAP decoding for apache:Map with a missing <value> checks the wrong variable, causing a NULL pointer dereference and segmentation fault. Affected branches are 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.

Likely exposure

Internet-facing PHP applications using the SOAP extension as a server and configured with typemaps are the primary concern. Systems running vendor-packaged PHP should also check Red Hat advisories and package status.

Exploitation context

The CVSS vector indicates network access, low complexity, no privileges, and no user interaction. KEV is false, and the provided sources do not state active exploitation or public exploit availability.

Researcher notes

The issue is limited by the provided evidence to denial of service through a NULL pointer dereference in PHP SOAP typemap decoding. Do not infer code execution, data exposure, or active exploitation without additional vendor or threat-intelligence confirmation.

Mitigation direction

  • Upgrade PHP to 8.2.31, 8.3.31, 8.4.21, 8.5.6, or later supported releases.
  • Apply applicable Red Hat security advisories for vendor-managed PHP packages.
  • Inventory and prioritize externally reachable PHP SOAP services using typemap configuration.
  • Restrict access to affected SOAP endpoints where business requirements allow.
  • Monitor affected services for crashes until patching is complete.

Validation and detection

  • Confirm PHP runtime versions across application servers and containers.
  • Verify whether the SOAP extension is enabled and used for server endpoints.
  • Identify SOAP server code paths with typemap configuration.
  • Check package manager or image metadata for fixed vendor builds.
  • Review service logs for segmentation faults or abnormal PHP worker exits.
