CVE-2025-61027
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedAn issue in the t_set_push component of openlink virtuoso-opensource v7.2.11 allows attackers to cause a Denial of Service (DoS) via crafted SQL statements.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceA denial-of-service vulnerability exists in the t_set_push component of OpenLink Virtuoso Open-Source Edition version 7.2.11. Attackers can cause the database service to become unavailable by submitting specially crafted SQL statements to the affected component.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify Virtuoso installationLocate the Virtuoso executable (isql-vt, virtuoso-t, or virtuoso.exe) or check for Virtuoso processes running on the system. Common paths include /usr/bin/virtuoso*, /opt/virtuoso/, or C:\Program Files\OpenLink Software\Virtuoso\Affected if Virtuoso Open-Source Edition is not installed or running
-
Confirm installed versionRun 'virtuoso-t --version' or 'isql-vt -?' to retrieve the version number, or check the Virtuoso console/web interface for version informationAffected if The installed version is 7.2.11 (the affected version)
-
Check t_set_push component accessibilityAttempt to connect to the Virtuoso instance via isql-vt or ODBC/JDBC and verify the t_set_push component is accessible. This may require checking SQL permissions or examining available stored proceduresAffected if t_set_push component is exposed and callable by the connecting user
-
Audit recent SQL activityReview Virtuoso server logs and audit trails for SQL statements involving t_set_push. Check logs in the Virtuoso database directory (typically logs/ subfolder) for t_set_push callsAffected if There are recent t_set_push calls from untrusted sources or anomalous patterns
A user is affected if they are running Virtuoso Open-Source Edition version 7.2.11 and the t_set_push component is accessible to untrusted users or showing anomalous SQL activity.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply the vendor-provided patch or upgrade to a patched version of Virtuoso. Until a patch is available, restrict database access to trusted personnel and monitor for anomalous SQL activity.
