AV:N/AC:H/PR:H/UI:R/S:U/C:H/I:H/A:H
Table owner is a low-privilege PostgreSQL role (PR:L not PR:H); escalation to superuser crosses a trust boundary warranting S:C; UI:R and AC:H preserved per vendor.

Lifecycle Timeline
2DescriptionCVE.org
PostgreSQL Anonymizer contains a vulnerability in the anon.anonymize_database_parallel() function that allows the owner of a table to run arbitrary code with superuser privilege. The issue is fixed in PostgreSQL Anonymizer 3.2.0 and later versions
AnalysisAI
Privilege escalation in PostgreSQL Anonymizer (Dalibo) prior to 3.2.0 allows a table owner to execute arbitrary code with full superuser privileges via the anon.anonymize_database_parallel() function. The vulnerability (CWE-250, Execution with Unnecessary Privileges) enables a low-to-high privilege escalation within the database server, granting complete C:H/I:H/A:H impact. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the attacker to hold table-owner privilege within a PostgreSQL instance where PostgreSQL Anonymizer prior to 3.2.0 is installed and `anon.anonymize_database_parallel()` is in use. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The vendor-supplied CVSS 3.1 score of 6.4 (AV:N/AC:H/PR:H/UI:R/S:U) reflects tightly constrained exploitation: the attacker must already hold high privileges (PR:H per vendor), attack complexity is high, and user interaction is required - factors that significantly reduce practical exploitability versus the C:H/I:H/A:H impact metrics alone. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Upgrade PostgreSQL Anonymizer to version 3.2.0 or later, which contains the vendor-released patch (see https://gitlab.com/dalibo/postgresql_anonymizer/-/issues/666). … Detailed patch versions, workarounds, and compensating controls in full report. |
