CVE-2026-88027 — Mass deletion and overwrite of embedded documents via query-operator injection in embedded record keys in MongoDB integration for Laravel
Improper neutralization of special elements in data query logic in the embedded-document relation handling of the MongoDB integration for Laravel can cause a caller-supplied embedded record identifier to be interpreted as a query condition rather than as a literal identifier. An authenticated user who can influence such an identifier may delete all embedded documents in a targeted record or overwrite an embedded document other than the intended target.
Who exploits it and how urgent it is
A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.
How the score was calculated
- EPSS 0.3% (30-day exploitation probability)+3
- Technical severity (high)+6
The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).
Triage
Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.
CISA SSVC assessment CISA
Three decision points CISA publishes for the CVEs it assesses (SSVC 2.0.3). A stakeholder decision, not a severity score.
Remediation
Fixes and mitigations documented by the sources — linked to the original advisory.
No fix documented by the sources we poll. That does not mean none exists: check the vendor advisory.
First 24 hours
Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.
- Identify exposed assets running the affected vendor/product/version combinations (Mongodb Laravel Mongodb, Mongodb Laravel MongoDB (PHP)).
- No fix documented in the sources: reduce exposure and monitor the vendor advisory.
- Search available logs for exploit probes, errors and authentication anomalies.
Affected scope
Vendor, product and versions as the sources word them.
| Vendor | Product | Versions | Status | Source |
|---|---|---|---|---|
| Mongodb | Laravel Mongodb | ≥ 4.0.0 and < 5.11.0 | Vulnerable | NIST National Vulnerability Database |
| Mongodb | Laravel MongoDB (PHP) | ≥ 4.0.0 and < 5.11.0 | Vulnerable | CVE Program (cve.org) e CISA ADP |

What should defenders know first?
CVE-2026-88027 is "Mass deletion and overwrite of embedded documents via query-operator injection in embedded record keys in MongoDB integration for Laravel", rated High. It affects Laravel Mongodb (Mongodb); versions are in the scope table. It is not in CISA KEV, which does not rule out exploitation. CVSS 8.1 describes technical severity. EPSS 0.27% estimates the probability of exploitation in 30 days; neither replaces your asset context. First verify whether exposed or business-critical assets run the affected versions, apply vendor fixes or mitigations, and preserve logs for review.
