CVE-2026-30941
Published: 10 March 2026
Summary
CVE-2026-30941 is a high-severity Improper Neutralization of Special Elements in Data Query Logic (CWE-943) vulnerability in Parseplatform Parse-Server. Its CVSS base score is 8.7 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 36.1th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified are NIST 800-53 RA-5 (Vulnerability Monitoring and Scanning) and SI-10 (Information Input Validation).
Deeper analysis
CVE-2026-30941 is a NoSQL injection vulnerability in Parse Server, an open source backend deployable on any Node.js infrastructure. It affects versions prior to 8.6.14 and 9.5.2-alpha.1, specifically in the password reset and email verification resend endpoints where the token field is passed to MongoDB queries without type validation. This allows injection of MongoDB query operators. Deployments using MongoDB with email verification or password reset enabled are vulnerable, with a CVSS v3.1 base score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N) and mapped to CWE-943 (Improper Neutralization of Special Elements in Data Query Logic).
An unauthenticated attacker can exploit this vulnerability remotely with low complexity by submitting crafted token values to the affected endpoints. Successful exploitation enables extraction of password reset and email verification tokens from the database. If the emailVerifyTokenReuseIfValid configuration is enabled, attackers can fully retrieve and reuse an email verification token to verify a user's email address without accessing their inbox.
The Parse Server security advisory (GHSA-vgjh-hmwf-c588) and release notes for versions 8.6.14 and 9.5.2-alpha.1 detail the fix, recommending immediate upgrades to these patched versions for all affected deployments.

Vulnerability details
Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to 8.6.14 and 9.5.2-alpha.1, NoSQL injection vulnerability allows an unauthenticated attacker to inject MongoDB query operators via the token field in…
more
the password reset and email verification resend endpoints. The token value is passed to database queries without type validation and can be used to extract password reset and email verification tokens. Any Parse Server deployment using MongoDB with email verification or password reset enabled is affected. When emailVerifyTokenReuseIfValid is configured, the email verification token can be fully extracted and used to verify a user's email address without inbox access. This vulnerability is fixed in 8.6.14 and 9.5.2-alpha.1.
