Description of CVE-2026-22599
A database-query injection vulnerability existed in the Strapi Content-Type Builder write API. An authenticated administrator could inject arbitrary database statements through the column.defaultTo attribute when creating or modifying a content type. Setting defaultTo as a tuple [value, { isRaw: true }] caused the value to be passed directly into Knex's db.connection.raw() during schema migration without sanitization, allowing arbitrary statement execution at the database layer. Depending on the database engine, this enabled arbitrary file read via database utility functions, denial of service via forced server crash on schema-migration error, and on engines that permit external program execution, remote code execution against the database server.
The patch addresses this by restricting all Content-Type Builder write APIs to development mode only. Production deployments running v5.33.2 or later return 404 for requests against /content-type-builder/content-types and related endpoints, removing the network-reachable attack surface entirely.
IoC's for CVE-2026-22599
Indicators that an instance running an unpatched version may have been exploited:
- HTTP access logs containing POST or PUT requests to
/content-type-builder/content-typesfrom a non-internal source. Regex pattern:(POST|PUT)\s+/content-type-builder/ - Database server logs containing unexpected DEFAULT clause values that reference filesystem-access or program-execution helper functions of your database engine
- Strapi server crashes immediately following a content-type creation or update, observed as the Node process exiting during the schema-migration step
- Files appearing under unexpected paths on the database host that match content-type DEFAULT values from the application
- Newly-created content-types named or shaped to extract specific data (attribute names like
passwd,etc,env,config)

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for @strapi/content-type-builder, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update @strapi/content-type-builder to 5.33.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2026-22599 is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like CVE-2026-22599 can be triaged on real exposure rather than presence alone.
Tailored to CVE-2026-22599. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
