Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
SSRF: Fetching remote URLs to parse public PR diffs is highly susceptible to SSRF. Without strict IP validation and redirect checks, attackers can coerce the agent into querying internal network metadata or local services.
Auth Bypass: Webhooks accepting external events without verifying cryptographic signatures allows malicious actors to forge events, triggering arbitrary PR-Agent evaluations and potentially exposing code context or modifying repository metadata.
SSRF: Feature components like help document retrieval that perform remote Git operations must robustly validate clone hosts to prevent exfiltration of internal secrets and source files.
