Back Sploitus Exploit for Improperly Controlled Sequential Memory Allocation in Php
Defensive self-check and response toolkit for the PHP2Shell crisis (CVE-2026-109618 / CVE-2026-109619).
> ⚠️ Defensive use only. No exploit code, no PoC, no attack traffic samples — in this repo, ever.
On 2026-10-21 the PHP Group shipped emergency fixes for two CVSS 9.2 flaws hiding in the PHP core for over a decade. Most of the web runs PHP, and the people hit hardest are small site owners on shared hosting who don't know their PHP version and can't upgrade by themselves.
3. **How do I buy time until I can patch?**
| `src/check.php` | 🚧 v0.1 WIP | One-command self-check. Compares the PHP branch against the patched floor **and** detects the SAPI (mod_php / PHP-FPM / php-cgi / FrankenPHP / LiteSpeed) — exploitability differs per SAPI, so a version check alone is not enough. See `docs/DESIGN.md`. |
| `templates/` | skeleton | Plain-language emergency report (zh-CN / en), including a -your-hosting-provider script for shared-hosting users. |
| `waf/` | skeleton | Adaptable WAF rule templates: ModSecurity, Cloudflare, Aliyun. Defensive filtering only. |
| `watch` | planned | Watches official PHP security advisories and notifies on new releases. |
| ≤ 8.1 | — | EOL, no official fix planned |
Per Wiz, every PHP release since 5.4 is affected by at least one of the two flaws.
v0.1.0 is being built in public right now. It will be one command:
- PHP Group security advisory, 2026-10-21 (php.net)
- GHSA-w8hw-w9fx-j79w (RCE via OOM corruption) / GHSA-6wmf-4rv5-p3rp (RCE via stale global state)
