Improper Validation of Unsafe Equivalence in Input

Overview fastify is an overhead web framework, for Node.js. Affected versions of this package are vulnerable to Improper Validation of Unsafe Equivalence in Input due to incomplete schema case normalization in lib/validation.js when compiling header schemas. An attacker can bypass schema-enforced...

CVE-2026-84428

fastify versions before 5.12.2 are vulnerable to a header validation bypass caused by incomplete case normalization in the JSON Schema Draft 7 dependencies keyword. While the library lowercases property keys and the root-level required array to accommodate HTTP's case-insensitive headers, it fail...

CVE-2026-84469

fastify versions before 5.12.2 decide whether to compile a request schema based on JavaScript truthiness, but JSON Schema Draft 7 defines the boolean false as a valid schema that rejects every instance. When an application assigns false to a route's body, querystring, params, or headers schema to...

CVE-2026-84469

fastify versions before 5.12.2 use JavaScript truthiness to decide whether to compile a request schema. Because JSON Schema Draft 7 defines the boolean false as a valid schema that rejects every instance, an application that assigns false to a route's body, querystring, params, or headers schema ...
