CVE-2026-88028: MongoDB Laravel MongoDB

Medium severity, CVSS 6.5. EPSS: 0.4% chance of exploitation in the next 30 days.

Improper neutralization of special elements in data query logic in the polymorphic relation handling of the MongoDB integration for Laravel can cause a caller-supplied relation identifier to be interpreted as a query condition rather than as a literal identifier. An authenticated user who can influence a stored relation identifier may cause an affected application to return a document other than the intended relation target.

Affected products

• MongoDB Laravel MongoDB: from 1.2.0, before 5.11.0 (fixed in 5.11.0)
