AI-Generated

The BSON encoder in the MongoDB PHP Driver is vulnerable due to insufficient validation of return values when handling documents that exceed libbson's size limit, potentially leading to an invalid encoder state. This flaw allows unauthenticated attackers to disrupt PHP workers or manipulate encoded documents by submitting excessively large data structures. Organizations utilizing the MongoDB PHP Driver should prioritize addressing this vulnerability to mitigate risks of service disruption and data integrity issues.

Original NVD Description

The BSON encoder in the MongoDB PHP Driver does not check some return values after a document exceeds libbson's size limit. This can leave the encoder in an invalid state. An unauthenticated actor who can cause an affected application to encode an unusually large data structure can terminate the PHP worker or cause the resulting document to omit fields. No MongoDB server connection or database authentication is required.
