CVE-2026-32763 is a high-severity flaw (CVSS 8.2) affecting kysely. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

Kysely is a type-safe TypeScript SQL query builder. Versions up to and including 0.28.11 has a SQL injection vulnerability in JSON path compilation for MySQL and SQLite dialects. The `visitJSONPathLeg()` function appends user-controlled values from `.key()` and `.at()` directly into single-quoted JSON path string literals (`'$.key'`) without escaping single quotes. An attacker can break out of the JSON path string context and inject arbitrary SQL

Affected: >= 0.26.0 and < 0.28.12

Fixed in: 0.28.12

Safe to downgrade to: a release before 0.26.0

1. Check installed version

npm ls kysely

2. UPGRADE to 0.28.12

npm install kysely@">=0.28.12"

3. If no update is available yet, DOWNGRADE to a release before 0.26.0

npm view kysely versions npm install kysely@"<0.26.0"

Downgrading can break dependent software and may reopen older bugs. Read the distro advisory first and test on a non-production host.

After downgrade

Restart the service, and keep the package held until a fixed release ships.
