# CVE-2024-39309: ZDI-CAN-23894: Parse Server literalizeRegexPart SQL Injection Authentication Bypass Vulnerability

**Signal:** High exploit likelihood. EPSS ranks it in the top 5% of all CVEs for likely exploitation in the next 30 days. (Computed from CISA KEV, EPSS and CVSS; not an editorial verdict.)

## Should you act?

- No confirmed exploitation. It is not in CISA’s KEV catalog and CISA’s SSVC assessment records no known exploitation. That can change quickly after a public write-up; re-check if you are affected.
- EPSS 20.2% , percentile 97: FIRST’s model estimates a 20.2% chance of exploitation activity in the next 30 days, higher than 97% of all scored CVEs (very high). EPSS is a probability, not a verdict.
- Remotely reachable with no login and no user interaction. If the vulnerable service is exposed to the internet, prioritize it.
- Only applies if your dependency tree includes parse-server (npm) < 6.5.7, fixed in 6.5.7 ; parse-server (npm) >= 7.0.0, < 7.1.0, fixed in 7.1.0 . Check your lockfile, including transitive dependencies.

## What it is

Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. A vulnerability in versions prior to 6.5.7 and 7.1.0 allows SQL injection when Parse Server is configured to use the PostgreSQL database. The algorithm to detect SQL injection has been improved in versions 6.5.7 and 7.1.0. No known workarounds are available.

## Affected packages

- npm `parse-server` < 6.5.7 → fixed: 6.5.7
- npm `parse-server` >= 7.0.0, < 7.1.0 → fixed: 7.1.0

## Affected products (CVE record)

- parse-community parse-server: < 6.5.7, >= 7.0.0, < 7.1.0

## Severity

- GitHub_M CVSS 3.1: 9.8 `CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H`
- GitHub CVSS 3.1: 9.8 `CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H`

## Exploitation

- CISA KEV: not listed (no confirmed in-the-wild exploitation known to CISA).
- CISA SSVC assessment: exploitation none , automatable no , technical impact total .
- FIRST EPSS (model of 2026-10-21): 20.17% probability of exploitation activity in the next 30 days; percentile 97.
