+# Security Analysis Memory - Gyro PHP
+
+## Summary: 30 files modified across 3 commits
+
+## Commit 1: Core Security Fixes
+
+### 1. CRITICAL: Insecure Token Generation (common.cls.php)
+- `create_token()` used `sha1(uniqid(mt_rand(), true))` - NOT cryptographically secure
+- **Fix**: Replaced with `bin2hex(random_bytes(20))` and `bin2hex(random_bytes(32))`
+
+### 2. CRITICAL: Insecure Deserialization (6 files)
+- `unserialize()` without `allowed_classes` restriction in:
+  - dbfield.serialized.cls.php, cache.acpu.impl.php, cache.file.impl.php
+  - cache.xcache.impl.php, dbdriver.sphinx.php
+- **Fix**: Added `['allowed_classes' => false]` to all calls
+
+### 3. CRITICAL: Password Hashing with MD5/SHA1 (md5.hash.php, sha1.hash.php)
+- Timing attack via loose `==` comparison
+- **Fix**: Replaced with `hash_equals()`, added bcrypt.hash.php
+
+### 4. HIGH: SQL Injection in escape_database_entity (dbdriver.mysql.php)
+- Backticks in entity names not escaped
+- **Fix**: Added `str_replace('`', '``', $obj)`
+
+### 5. HIGH: Host Header Injection (requestinfo.cls.php)
+- `HTTP_X_FORWARDED_HOST` used directly without validation
+- **Fix**: Validate host against configured domain
+
+### 6. HIGH: phpinfo() without access control (phpinfo.controller.php)
+- **Fix**: Added Config::TESTMODE check
+
+### 7. MEDIUM: Session Security (session.cls.php)
+- Missing SameSite, httponly, strict mode
+- Deprecated session.bug_compat_42
+- **Fix**: Added SameSite=Lax, strict mode, httponly defaults
+
+### 8. MEDIUM: XSS in ConverterHtmlEx (htmlex.converter.php)
+- Missing HTML escaping in heading output
+- **Fix**: Added GyroString::escape()
+
+### 9. MEDIUM: Missing Security Headers (pageviewbase.cls.php)
+- **Fix**: Added X-Content-Type-Options, X-Frame-Options, Referrer-Policy
+
+## Commit 2: Command Injection & Path Traversal Fixes
+
+### 10. CRITICAL: Command Injection in jcssmanager (5 files)
+- webpack, uglifyjs, postcss, csso, yui compressors all used exec() without escapeshellarg()
+- **Fix**: Added escapeshellarg() to all file path and option arguments
+
+### 11. HIGH: Path Traversal in deletedialog (3 template files)
+- `get_table_name()` used directly in include paths
+- **Fix**: Added basename() + path traversal character stripping
+
+### 12. HIGH: eval() in punycode uctc.php
+- **Fix**: Replaced with call_user_func()
+
+### 13. MEDIUM: shell_exec('mkdir') in install (check_preconditions.php)
+- **Fix**: Replaced with PHP native mkdir()
+
+## Commit 3: XSS, Weak Randomness & Permissions
+
+### 14. HIGH: XSS in punycode example.php
+- $_SERVER['PHP_SELF'] and $_REQUEST['lang'] output without escaping
+- **Fix**: Added htmlspecialchars()
+
+### 15. MEDIUM: XSS in wymeditor tidy plugin
+- $_REQUEST['html'] processed without Content-Type header
+- **Fix**: Added Content-Type header, fixed deprecated magic_quotes check
+
+### 16. MEDIUM: Weak rand() for feed tokens (notificationssettings.model.php)
+- **Fix**: Replaced rand() with random_int()
+
+### 17. LOW: Insecure chmod 0777 (check_preconditions.php)
+- **Fix**: Changed to 0755
