CVE-2024-23833 is a high-severity (CVSS 7.5) Path Traversal vulnerability in org.openrefine:database. 1 public exploit reference exists, so weaponization risk is real. A fix is available for org.openrefine:database — see the affected versions and patch details below.
OpenRefine JDBC Attack Vulnerability
Exploitation Status
No confirmed exploitation observed yet
- CISA assesses this as automatable — exploitation doesn’t require manual, per-target effort, which raises the odds of mass scanning and opportunistic attacks.
- CISA’s own triage has not observed active exploitation or public proof-of-concept code for this CVE as of its last assessment.

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-2024-23833 plotted by exploitation likelihood (EPSS) against impact (CVSS). The shaded corner — EPSS 50%+ and CVSS 7.0+ — is where this CVE doesn't sit, though severity or exploitability alone can still warrant action.
Where this sits among everything scored
Of 377,636 CVEs with a current EPSS score, this one falls in the < 10% band (highlighted). Real counts from FIRST.org, not a sample — log-scaled since the landscape is heavily right-skewed.

Description
Summary
A jdbc attack vulnerability exists in OpenRefine(version<=3.7.7)
Details
Vulnerability Recurrence
Start by constructing a malicious MySQL Server (using the open source project MySQL_Fake_Server here).
Then go to the Jdbc connection trigger vulnerability
Vulnerability Analysis
This vulnerability is the bypass of CVE-2023-41887 vulnerability repair, the main vulnerability principle is actually the use of official syntax features, as shown in the following figure, when the connection we can perform parameter configuration in the Host part
In com.google.refine.extension.database.mysql.MySQLConnectionManager#getConnection method in the final JdbcUrl structure
That is, in the toURI method call here, you can see that the Host part is directly concatenated for any verification, which can be bypassed using the address feature of mysql

PoC
Complete instructions, including specific configuration details, to reproduce the vulnerability.
Type: MySQL
Host: 127.0.0.1:3306,(host=127.0.0.1,port=3306,autoDeserialize=true,allowLoadLocalInfile=true,allowUrlInLocalInfile=true,allowLoadLocalInfileInPath=true),127.0.0.1
Port: 3306
User: win_hosts
Database: test
Impact
Due to the newer MySQL driver library in the latest version of OpenRefine (8.0.30), there is no associated deserialization utilization point, so original code execution cannot be achieved, but attackers can use this vulnerability to read sensitive files on the target server.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.openrefine:database, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update org.openrefine:database to 3.7.8 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2024-23833 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-2024-23833 can be triaged on real exposure rather than presence alone.
Tailored to CVE-2024-23833. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Fixing This On Your OS
If you run this on a Linux distribution, patch through your package manager against the distro's own security advisory below — it tracks the exact backported fix for your release, which can ship on a different timeline (and sometimes a different severity) than the upstream project.
Frequently Asked Questions
Is CVE-2024-23833 in your dependencies?
O3 Security finds CVE-2024-23833 across Maven dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
