CVE-2026-7262 PUBLISHED

NULL pointer dereference in SOAP apache:Map decoder with missing <value>

Assigner: php
Reserved: 28.04.2026 Published: 10.05.2026 Updated: 10.05.2026

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.
