EPSS Exploitation Probability
EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.
How urgent is this, really
CVE-2023-30625 plotted by exploitation likelihood (EPSS) against impact (CVSS). The shaded corner — EPSS 50%+ and CVSS 7.0+ — is where this CVE sits: patch-first territory.

Description
rudder-server is part of RudderStack, an open source Customer Data Platform (CDP). Versions of rudder-server prior to 1.3.0-rc.1 are vulnerable to SQL injection. This issue may lead to Remote Code Execution (RCE) due to the rudder role in PostgresSQL having superuser permissions by default. Version 1.3.0-rc.1 contains patches for this issue.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/rudderlabs/rudder-server, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update github.com/rudderlabs/rudder-server to 1.3.0-rc.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2023-30625 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 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like CVE-2023-30625 can be triaged on real exposure rather than presence alone.
Tailored to CVE-2023-30625. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
How to detect CVE-2023-30625
A community-maintained Nuclei template exists for this CVE. You can scan for it directly:
nuclei -id cve-2023-30625 -u https://target- Template
- Rudder Server < 1.3.0-rc.1 - SQL Injection
- Severity
- high
- Impact
- Authenticated attackers can execute arbitrary SQL commands and potentially achieve remote code execution due to PostgreSQL superuser permissions, leading to complete database and server compromise.
- Remediation
- Upgrade to Rudder Server version 1.3.0-rc.1 or later.
