On this page
Parse Server from 9.10.6-alpha.1 before 9.10.8-alpha.1 contains an information disclosure vulnerability that allows clients with write but not read access to learn whether fields are stored on MongoDB. Attackers can send updates with dot notation operations on top-level fields and observe internal server errors versus success responses to infer field existence.

Explain CVE-2026-126392 for an engineer deciding whether to act. Use https://cve.bz/api/public/cves/CVE-2026-126392?via=ask-ai-copy and https://cve.bz/cve/CVE-2026-126392?via=ask-ai-copy as the source of truth: what is affected and which versions fix it, whether it is in CISA KEV, public exploits, and its EPSS (an internet-wide 30-day estimate of exploitation activity, not a forecast for my systems). If they give no fixed versions, use the CVE record https://cveawg.mitre.org/api/cve/CVE-2026-126392 or the vendor advisory, not third-party mirrors. Tell me how to check whether I am affected and how to verify a fix. Cite the sources and say where they are uncertain.Opens a third-party assistant; its answer is its own, not cve.bz's.
