Security Audit: 2 Critical, 2 High, 3 Medium Vulnerabilities Found

[Pyiner]

Security Audit Report — Bonfida Token Vesting Program

Automated security analysis of the token-vesting program, identifying 7 actionable vulnerabilities across the program's instruction handlers.

Critical Findings (2)

• V-01: Missing owner check on vesting_account in process_unlock — PDA key is validated but vesting_account.owner == program_id is never checked (unlike process_create which does)
• V-02: Same missing owner check in process_change_destination — enables destination redirection

High Findings (2)

• V-03: mint_address stored during creation is never validated during unlock
• V-04: Integer overflow in process_unlock amount accumulation (uses += instead of checked_add, inconsistent with process_create)

Medium Findings (3)

• V-05: Missing SPL Token program ID validation in process_create (checked in unlock, not in create)
• V-06: No validation of new destination token account mint in change_destination
• V-07: Missing payer signer check and system program validation in process_init

Each finding includes:

• Detailed description and affected code location
• Impact analysis
• Proof of concept / reproduction steps
• Proposed code fix
