Risk Analysis

Parse Server versions prior to 5.5.2 and 6.2.1 are vulnerable to remote code execution via a prototype pollution sink in the MongoDB BSON parser. This critical flaw has a CVSS score of 9.8 and is remotely exploitable. It allows attackers to execute arbitrary code on the host.

No public exploit is known, and it is not in the CISA KEV.

Recommended Action

Upgrade Parse Server to version 5.5.2 or 6.2.1 immediately.

Generated by the CTIWATCH analysis pipeline from this CVE's metadata (CVSS, EPSS, KEV status, exploit intelligence). Verify against vendor advisories before acting.

Technical Analysis

CVE-2023-36475 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.

A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 9.8.
