The official PHP SDK is deprecated and no longer actively maintained. Version4.x requires PHP8.1+ with json/openssl and documents OAuth2 plus legacy WSSE.

Scope: Verified material concerns customer-side PHP integration and operation. Provider-platform PHP2Shell impact, non-impact and patch deployment remain unconfirmed. Listed PHP minimums are compatibility requirements, not evidence of an incident fix.

What users should do

Inventory SDK dependencies and confirm a current API/OAuth2 migration plan with support before testing. Ask the runtime administrator to confirm PHP security updates.
