GHSA-2598-2f59-rmhq
CRITICALGHSA-2598-2f59-rmhq is a critical-severity (CVSS 9.8) SQL Injection vulnerability in sequelize. 1 public exploit reference exists, so weaponization risk is real. O3 Security confirms whether GHSA-2598-2f59-rmhq is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.

Blast Radius
Weekly download volume for affected packages — a proxy for how broadly this vulnerability is deployed.
sequelizenpmDescription
Versions of sequelize prior to 3.35.1 are vulnerable to SQL Injection. The package fails to sanitize JSON path keys in the Postgres dialect, which may allow attackers to inject SQL statements and execute arbitrary SQL queries.
Recommendation
Upgrade to version 3.35.1 or later.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|
| 📦npm | sequelize | all versions | 3.35.1 |

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for sequelize. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Fix
Update sequelize to 3.35.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-2598-2f59-rmhq is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 pinpoints whether GHSA-2598-2f59-rmhq is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to GHSA-2598-2f59-rmhq. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-2598-2f59-rmhq in your dependencies?
O3 detects GHSA-2598-2f59-rmhq across npm dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
