This omission permits an attacker to terminate the JSON path string and injected malicious SQL into the query. The flaw is a classic SQL Injection (CWE\u201189) that can allow an attacker to read, modify or delete data in the database, thereby compromising confidentiality, integrity, and availability of the application\u2019s data.", "risk_and_exploitability": "The vulnerability carries a high severity with a CVSS score of 8.2. Its EPSS score is below 1% and it is not listed in the CISA KEV catalog, suggesting a low likelihood of widespread exploitation for the time being. However, the attack vector is straightforward: an attacker who can influence data passed to .key() or .at() can inject arbitrary SQL. This can provide the same level of access as the application, potentially leading to data exfiltration or modification."}}}}, "created": "2026-03-20T08:54:19.464725+00:00", "updated": "2026-04-09T08:29:44.124996+00:00", "vendors": ["kysely-org", "kysely-org$PRODUCT$kysely"]}
