How do I detect CVE-2026-88027 in my code and dependencies?

Identify every host running the affected component and compare the installed build against the fixed version below — for source-built or distro-packaged software the version string, not a lockfile, is the source of truth (`dpkg -l`, `rpm -q`, or the binary's own `--version`).

How do I mitigate CVE-2026-88027 if there is no patch (or I can't update yet)?

If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.

Is CVE-2026-88027 actively exploited in the wild?

No public exploit code has been indexed for CVE-2026-88027 yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

Description

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.
