CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:HCVSS and EPSS are reproduced from their sources (NVD, FIRST EPSS). Risk Priority is our own derived reading, not an NVD score.
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, exploitation aligns with the MITRE ATT&CK technique Junk Data (T1001.001); ranked in the top 24% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SI-10 (Information Input Validation) — see the control section below for these in your framework.
Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
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.

Mitigating Controls (NIST 800-53 r5) AI
Developer testing and evaluation finds code paths that accept and execute externally influenced strings.
Input validation directly stops untrusted data from being used to construct executable code without neutralization.
Least privilege limits the damage an injected code fragment can perform once executed.
Requiring documented secure development standards and tools enforces use of safe code-generation APIs and escaping.

PR.PS-06's SDLC practices directly target injection flaws via secure coding and testing (mostly), yet as a single broad outcome it leaves many code-generation specifics unaddressed (partial).
PR.DS-10 protects runtime data confidentiality/integrity but has no bearing on neutralizing externally influenced input during code generation, so neither direction shows any preventive effect.
