MongoDB

Alienbin is an anonymous code and text sharing web service. In 1.0.0 and earlier, the /save endpoint in server.js drops and recreates the MongoDB TTL index on the entire post collection for every new paste submission.

Feathersjs is a framework for creating web APIs and real-time applications with TypeScript or JavaScript. From 5.0.0 to before 5.0.42, Socket.IO clients can send arbitrary JavaScript objects as the id argument to any service method (get, patch, update, remove). The transport layer performs no type checking on this argument. When the service uses the MongoDB adapter, these objects pass through getObjectId() and land directly in the MongoDB query as operators. Sending {$ne: null} as the id mat...

NoSQL injection in Parse Server's password reset and email verification endpoints allows unauthenticated attackers to extract authentication tokens by injecting MongoDB query operators through the unvalidated token parameter. Affected deployments running MongoDB with these features enabled are vulnerable to email verification bypass and password reset token theft. The vulnerability is fixed in versions 8.6.14 and 9.5.2-alpha.1.

MongoDB server crashes when an authenticated user executes a $geoNear aggregation pipeline with malformed index hints, enabling denial of service attacks by any user with database access. This medium-severity vulnerability requires valid credentials and does not affect confidentiality or integrity, only availability. No patch is currently available.

An authenticated attacker could exploit this to modify database filters without proper access restrictions, potentially altering query behavior and data visibility. No patch is currently available.

MongoDB's Query Planner can be exhausted of available memory when processing specially crafted complex queries, leading to service denial through out-of-memory crashes. Authenticated users can trigger this condition without user interaction, affecting availability of MongoDB instances. No patch is currently available to address this vulnerability.

MongoDB Server can be crashed via denial of service by authenticated users who craft expressions that generate deeply nested documents, exploiting missing recursion depth validation that causes out-of-memory failures. This vulnerability affects deployments where database access is granted to untrusted users and requires valid credentials to exploit. No patch is currently available.

MongoDB proxy port connections bypass connection accounting mechanisms, allowing unauthenticated remote attackers to exhaust server resources and trigger denial of service without authentication. Servers relying on connection limits for resource management are vulnerable to crashes when connection counts are artificially inflated through the proxy protocol. No patch is currently available for this high-severity issue affecting MongoDB deployments.

MongoDB replica set replication can be disrupted when oversized documents are inserted, preventing secondaries from synchronizing oplog entries with the primary and potentially causing server crashes. Authenticated users with write access can trigger this denial of service condition to destabilize replica set availability. No patch is currently available for this vulnerability.

MongoDB server's resource locking mechanism can cause unintended collisions between collections due to improper internal encoding, leading to service denial of availability. Authenticated users can trigger this condition to disrupt database operations across affected collections without requiring user interaction. No patch is currently available to remediate this vulnerability.

MongoDB instances are vulnerable to denial of service attacks when processing specially crafted unauthenticated messages that trigger memory exhaustion and server crashes. An unauthenticated remote attacker can exploit this vulnerability to disable MongoDB availability without requiring valid credentials or user interaction. No patch is currently available for this vulnerability.

User-controlled chunkSize metadata from MongoDB lacks appropriate validation allowing malformed GridFS metadata to overflow the bounding container. [CVSS 6.5 MEDIUM]

Packetbeat's MongoDB protocol parser fails to properly validate array indices, enabling attackers to trigger buffer overflows via malformed network packets sent to monitored interfaces. Organizations running Packetbeat with MongoDB protocol parsing enabled could experience denial of service conditions when processing specially crafted traffic. No patch is currently available for this vulnerability.

Flagforge versions 2.3.2 and earlier suffer from a Regular Expression Denial of Service (ReDoS) vulnerability in the user profile API endpoint that accepts unvalidated usernames containing regex metacharacters, allowing unauthenticated remote attackers to trigger excessive CPU consumption and deny service to legitimate users. The MongoDB regex engine processes these malicious patterns inefficiently, making the platform unavailable without administrator intervention. No patch is currently available; users should implement WAF rules to filter regex metacharacters from username inputs as a temporary mitigation.

MongoDB Server may be susceptible to stack overflow due to JSON parsing mechanism, where specifically crafted JSON inputs may induce unwarranted levels of recursion, resulting in excessive stack space consumption. Such inputs can lead to a stack overflow that causes the server to crash which could occur pre-authorisation. This issue affects MongoDB Server v7.0 versions prior to 7.0.17 and MongoDB Server v8.0 versions prior to 8.0.5. The same issue affects MongoDB Server v6.0 versions prior to 6.0.21, but an attacker can only induce denial of service after authenticating.
