CVE-2025-6713: MongoDB Server may be susceptible to privilege escalation due to $mergeCursors stage

Noroxi assessment

Priority: Monitor (action score 26/100)

  • Public proof-of-concept code exists (GitHub); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.46% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • According to the record, no fixed version is available yet.

Low priority for now. Update when a fix is released; follow the vendor's advisory.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

An unauthorized user may leverage a specially crafted aggregation pipeline to access data without proper authorization due to improper handling of the $mergeCursors stage in MongoDB Server. This may lead to access to data without further authorisation. This issue affects MongoDB Server MongoDB Server v8.0 versions prior to 8.0.7, MongoDB Server v7.0 versions prior to 7.0.19 and MongoDB Server v6.0 versions prior to 6.0.22
