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.

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. 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 org.openrefine:database to 3.7.8 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-6p92-qfqf-qwx4 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-6p92-qfqf-qwx4 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-6p92-qfqf-qwx4. 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-6p92-qfqf-qwx4 in your dependencies?
O3 detects GHSA-6p92-qfqf-qwx4 across Maven dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
