Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Command Injection: The Parser component executes shell commands via the exec function using file path arguments. If these file paths contain shell-metacharacters and are not properly sanitized, an attacker can execute arbitrary commands on the host system.
Denial of Service: Processing large or malformed SQL dumps with complex, nested negative-lookahead regular expressions in preg_replace can trigger catastrophic backtracking, exhausting system memory and causing a stack overflow.
Denial of Service: The HTTP client connector is vulnerable to infinite redirection loops if meta refresh tags resolve back to the current canonicalized URL, leading to resource exhaustion.
