How Two WordPress Core Bugs Chained into Pre-Auth RCE

An unauthenticated stored XSS (CVE-2026-93485) in WordPress core's wpautop() turns crafted comments into zero-click XSS, escalating to RCE via the admin session. Fixed in 7.1.1, backported to 4.7.36.

Post-auth RCE in Cisco Smart Software Manager (CSSM): command injection in nginx certificate upload, where openssl checks run via childProcess.execSync. Cisco silently patched it in 10-202608.

Using HacktronAI's OpenAI Discourse hack disclosure, this article covers sandboxing, runtime protection, and AI-assisted defense to shrink the blast radius of RCE across interconnected apps.

Affects all WordPress installations from version 4.7.0 through 7.1.0 without requiring credentials or interaction beyond opening a post. Administrators should verify upgrading to 7.1.1 or backported releases, and monitor server logs for suspicious comment payloads and unexpected plugin uploads.

While remote code execution depends on runtime prerequisites like PEAR, the unauthenticated LFI primitive resides directly in WordPress Core and affects all major branches from 4.7.0 through 7.1.1.
