An authenticated remote attacker with low privileges can cause a server failure due to an incorrect evaluation of the number of files during their batch deletion [1].

The vulnerability is present in product:

• MongoDB Server; >=7.0, <7.0.26; >=8.0, <8.0.13; >=8.1, <8.1.2;

An authenticated remote attacker with low privileges can exploit a faulty object size check when processing time series in MongoDB Server and send an oversized BSON document, which may cause the process to terminate [2].

The vulnerability is present in product:

• MongoDB Server; >=7.0, <7.0.26; >=8.0, <8.0.16; >=8.2, <8.2.1;

CVSS: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N

More information:

• CVE-2025-13507 at cve.org, NVD
• CWE-1284: Improper Validation of Specified Quantity in Input at cwe.mitre.org

The vulnerability was publicly disclosed 25. 11. 2025.

An authenticated local attacker who can send bulk operations to mongodb/mongodb-extension (an extension used by MongoDB C Driver and MongoDB PHP Driver) can exploit improper handling of excessively large parameters (mongoc_bulk_operation_t), which may cause reading of invalid memory and thus an application failure or potential disclosure of sensitive data [3].

The vulnerability is present in products:

• mongo-c-driver; >=1.9.0, <=1.30.5; >=2.0.0, <=2.1.1;
• mongodb-php-driver; >=0, <=2.1.2;
