CVE-2023-30625 has a CVSS score of 8.8/10, rated HIGH. Immediate patching is strongly recommended.

Which packages are affected by CVE-2023-30625?

CVE-2023-30625 affects the following packages: github.com/rudderlabs/rudder-server (Go). Ecosystems affected: Go.

How do I fix CVE-2023-30625?

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.

How do I detect CVE-2023-30625 in my Go dependencies?

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.

How do I mitigate CVE-2023-30625 if there is no patch (or I can't update yet)?

Until you can upgrade, make sure every query built from user input uses parameterised statements or a prepared-statement API rather than string concatenation, and reduce the database account's privileges so an injected query cannot read or alter data beyond what the feature needs.

Is CVE-2023-30625 actively exploited in the wild?

Yes. There are 2 known exploit references for CVE-2023-30625, including 2 in-the-wild exploitations observed on GitHub and other sources. Treat this as actively exploitable and prioritize patching immediately. All exploit code should only be run in an isolated sandbox environment for research or authorized testing — never against production systems without explicit written authorization.

What is the EPSS score for CVE-2023-30625?

CVE-2023-30625 has an EPSS (Exploit Prediction Scoring System) score of 85.8%, placing it in the 100th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. A score above 50% indicates significantly elevated exploitation risk — immediate patching is strongly recommended.

What type of vulnerability is CVE-2023-30625?

CVE-2023-30625 is classified as SQL Injection (CWE-89). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation. This is a high-impact weakness class that often enables remote code execution or data exposure.

Is there exploit tooling available for CVE-2023-30625?

A Nuclei detection template exists for CVE-2023-30625, meaning automated scanners can fingerprint it. Public exploit tooling significantly increases real-world risk — prioritize patching and ensure detection coverage. Exploit tooling should only ever be used in isolated, authorized testing environments.

When was CVE-2023-30625 published, and has it been updated?

CVE-2023-30625 was published on June 16, 2023 and was last updated on October 28, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

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.

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.
