CVE-2026-120060
psqlODBC trusts counts and lengths in server data in three places. SQLBulkOperations uses a server-supplied row count in a size subtraction that can underflow. SQLStatistics iterates index keys using a server-supplied key count without bounding it to the fixed storage. Bytea octal decoding reads up to two bytes past the end of a truncated escape sequence. A server not trusted under current SSL settings can crash the client or make it read out of bounds. Versions before psqlODBC 18.00.0006 are affected.
Executive briefing
This record describes a reported software or hardware weakness. The description and CVSS rating are source metadata; practical risk depends on whether your environment uses an affected product/version and whether the vulnerable component is reachable and configured in an exploitable way.
Severity & exploitability
CVSS vector: CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:L/I:N/A:H
Impacted products and platforms
Specific affected product configurations are not currently available in the NVD record. Review vendor advisories and validate applicability against your asset inventory.
How it works and what it could affect
The NVD description is the authoritative short summary currently available for this record. A detailed technical mechanism is not inferred when the source record does not provide one.
Weakness classification: CWE-125CWE-191
Review the CVSS attack characteristics above to understand whether exploitation is network/local, whether privileges or user interaction are required, and which confidentiality, integrity or availability impacts are scored.
Remediation and recommended response
- Identify exposure: compare the affected product and version ranges below with your asset inventory, software bill of materials, endpoint inventory and externally exposed services.
- Remediate: review the linked vendor security advisory or patch notes, upgrade to a fixed release, or apply the vendor-provided workaround if an upgrade cannot be completed.
- Mitigate while patching: restrict network access to the vulnerable service, disable the affected feature where operationally safe, and monitor vendor/CERT advisories for updated guidance.
- Validate: confirm the fixed version or mitigation on representative systems, run a vulnerability rescan, and retain change evidence.
