GHSA-5FW2-8JCV-XH87 Parse Server: Account takeover via operator injection in authentication data identifier

Impact An unauthenticated attacker can take over any user account that was created with an authentication provider that does not validate the format of the user identifier e.g. anonymous authentication. By sending a crafted login request, the attacker can cause the server to perform a...

GHSA-2CJM-2GWV-M892 Parse Server's OAuth2 adapter shares mutable state across providers via singleton instance

Impact Parse Server's built-in OAuth2 auth adapter exports a singleton instance that is reused directly across all OAuth2 provider configurations. Under concurrent authentication requests for different OAuth2 providers, one provider's token validation may execute using another provider's...

Race Condition

Overview parse-server is a version of the Parse backend that can be deployed to any infrastructure that can run Node.js. Affected versions of this package are vulnerable to Race Condition in the OAuth2 auth adapter. An attacker can gain unauthorized access by exploiting a race condition that caus...

GHSA-MWV9-GP5H-FRR4 Sveltejs devalue's `devalue.parse` and `devalue.unflatten` emit objects with `__proto__` own properties

In some circumstances, devalue.parse and devalue.unflatten could emit objects with proto own properties. This in and of itself is not a security vulnerability and is possible with, for example, JSON.parse as well, but it can result in prototype injection if downstream code handles it incorrectly:...

Parse Server has a SQL injection via query field name when using PostgreSQL

Impact An attacker with access to the master key can inject malicious SQL via crafted field names used in query constraints when Parse Server is configured with PostgreSQL as the database. The field name in a $regex query operator is passed to PostgreSQL using unparameterized string interpolation...

BIT-PARSE-2026-31828 Parse Server has an LDAP injection via unsanitized user input in DN and group filter construction

Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to 9.5.2 and 8.6.26, the LDAP authentication adapter is vulnerable to LDAP injection. User-supplied input authData.id is interpolated directly into LDAP Distinguished Names DN and group...

BIT-PARSE-2026-31800 Parse Server: Classes `_GraphQLConfig` and `_Audience` master key bypass via generic class routes

Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to 9.5.2 and 8.6.25, the GraphQLConfig and Audience internal classes can be read, modified, and deleted via the generic /classes/GraphQLConfig and /classes/Audience REST API routes withou...
