Summary

CVE-2023-51784 is a critical-severity Code Injection (CWE-94) vulnerability in Apache Inlong. Its CVSS base score is 9.8 (Critical).

Operationally, ranked in the top 8.3% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.

Deeper analysis

CVE-2023-51784 is a code injection vulnerability, tracked under CWE-94, that affects Apache InLong versions 1.5.0 through 1.9.0. The flaw stems from improper control over code generation and carries a CVSS 3.1 score of 9.8, indicating that unauthenticated network attackers can achieve full remote code execution on affected instances.

An attacker with no credentials or user interaction can send specially crafted requests to an exposed InLong deployment and execute arbitrary code on the underlying server, potentially compromising data confidentiality, integrity, and availability.

Apache has published mitigation guidance directing users to upgrade to version 1.10.0; for environments that cannot perform a full upgrade, the project recommends applying the fix from pull request 9329.

The associated EPSS score has remained flat at 0.0708 with no material increase after disclosure, and no public reports of active exploitation have appeared in the referenced advisories.
