Summary

CVE-2026-4594 is a medium-severity SQL Injection (CWE-89) vulnerability in Feishu (inferred from references). Its CVSS base score is 6.9 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 13.1th 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 SI-10 (Information Input Validation) and SI-2 (Flaw Remediation).

Deeper analysis

CVE-2026-4594 is a SQL injection vulnerability in the Erupt framework, versions up to 1.13.3. The issue affects the geneEruptHqlOrderBy function in the file erupt-data/erupt-jpa/src/main/java/xyz/erupt/jpa/dao/EruptJpaUtils.java, where manipulation of the sort.field argument leads to SQL injection in Hibernate.

The vulnerability can be exploited remotely by unauthenticated attackers with low attack complexity and no user interaction required, as indicated by its CVSS 3.1 base score of 7.3 (AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L). Successful exploitation allows limited impacts on confidentiality, integrity, and availability through SQL injection.

Advisories from VulDB note that the exploit has been publicly disclosed and may be used, with the vendor contacted early but providing no response. No patches or specific mitigations are mentioned in the available references.

The vulnerability is associated with CWE-89 (SQL Injection) and CWE-564 (SQL Injection: Hibernate).
