How severe is CVE-2026-82039?

No CVSS score has been assigned to CVE-2026-82039 yet. Review the advisory details and affected package list to assess your exposure.

Which packages are affected by CVE-2026-82039?

Affected package information for CVE-2026-82039 is not yet fully mapped. Check the official advisory links for details.

How do I fix CVE-2026-82039?

Upgrade the affected component to the fixed release for CVE-2026-82039, or apply your distribution's backported patch — distro builds are often patched at an older version number, so check your vendor's advisory rather than the upstream version alone.

How do I detect CVE-2026-82039 in my code and dependencies?

Identify every host running the affected component and compare the installed build against the fixed version below — for source-built or distro-packaged software the version string, not a lockfile, is the source of truth (`dpkg -l`, `rpm -q`, or the binary's own `--version`).

How do I mitigate CVE-2026-82039 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-2026-82039 actively exploited in the wild?

No public exploit code has been indexed for CVE-2026-82039 yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

What is the EPSS score for CVE-2026-82039?

CVE-2026-82039 has an EPSS (Exploit Prediction Scoring System) score of 0.3%, placing it in the 25th 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. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

What type of vulnerability is CVE-2026-82039?

CVE-2026-82039 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.

When was CVE-2026-82039 published, and has it been updated?

CVE-2026-82039 was published on October 2, 2026 and was last updated on October 6, 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

UTMStack before 11.2.16 contains a SQL injection vulnerability in UtmAssetGroupService.searchQueryBuilder() that allows authenticated attackers to inject arbitrary SQL by supplying malicious assetType and groupName values that are inserted unsanitized into a native PostgreSQL query via String.format(). Attackers can exploit the GET /api/utm-asset-groups/searchGroupsByFilter endpoint to execute arbitrary SQL with DBA privileges, enabling full database read, data modification, and potential filesystem access.
