Preliminary research
PHP2Shell: A tale of two PHP remote vulnerabilities
AI-collected research leads through 3 November 2026, including a November–October–September missed-article review and a targeted multilingual search alongside earlier community-source sweeps. Unranked, incomplete, not community-vetted, and subject to change.
Shows how memory-limit interruptions expose partially initialized HashTables and leave request-owned session or decoder state alive across requests. HTTP upload parsing supplies both memory pressure and early consumers; Apache mod_php and PHP-FPM differ because failed startup terminates FPM workers.
