Recurring patterns

The bug types that recur here, drawn from past fixes, not open vulnerabilities.

Path Traversal: Writing files outside of the public output directory via relative path aliases or malicious alias targets can lead to arbitrary write primitives on host systems. Remediation demands unified path prefix validation.

Server-Side Request Forgery (SSRF): Attackers can bypass remote lookup controls using alternative IPv4 representation formats (integer, hex, octal) or through crafted redirects. Standardizing on canonicalized, fully resolved IP validations is crucial.

Command Injection: Executing external helper tools, such as git or Node, can allow untrusted local binaries or untrusted project structures to execute arbitrary code. Using system-aware path validation is necessary to exclude current-directory lookups on Windows.
