[SECURITY] AegisVale-001: Unnecessary Inline Assembly (CWE-1109, Medium)

[group3vigil]

Security Disclosure — AegisVale-GRAPH-001

Reported to: The Graph Security Team
Date: 2026-08-18
Severity: Medium | CWE: CWE-1109
Status: Open

---

Executive Summary

During security research of graphprotocol/contracts, we identified instances of unnecessary inline assembly that reduce defense-in-depth protections and may introduce potential security risks.

---

Findings

Inline Assembly Without Return Value Checks

Assembly blocks using call() do not check return values, silently swallowing call failures.

Risk: Silent call failures may bypass critical guards; re-entrancy exposure.

---

Recommended Remediation

1. Add require(success) checks after all low-level calls in assembly
2. Document all assembly with NatSpec comments
3. Replace assembly with Solidity equivalents where possible
