Summary

CVE-2023-26750 is a critical-severity SQL Injection (CWE-89) vulnerability in Yiiframework Yii. Its CVSS base score is 9.8 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique Protocol or Service Impersonation (T1001.003); ranked in the top 22% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

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-2023-26750 is a SQL injection vulnerability in the Yii 2 Framework prior to version 2.0.47 that permits remote code execution through the runAction function. The issue is tracked under CWE-89 and CWE-79 and carries a CVSS 3.1 base score of 9.8. The framework maintainers have stated that the flaw resides in third-party code rather than the Yii codebase itself.

An unauthenticated remote attacker can invoke runAction over the network to inject SQL and achieve arbitrary code execution, resulting in full confidentiality, integrity, and availability impact on affected installations.

Public discussion of the issue is contained in the referenced GitHub issue thread, which includes maintainer comments reiterating that the root cause lies outside the framework and providing guidance on responsible disclosure and patching of the implicated third-party component. The associated EPSS score reached a peak of 0.1364 and currently stands at 0.1102.

Likely Mitigating Controls AI

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.

CA-8 Penetration Testing
addresses: CWE-79 CWE-89

Penetration testing submits XSS payloads to web applications, detecting cross-site scripting flaws for subsequent remediation.

SI-10 Information Input Validation
addresses: CWE-79 CWE-89

Validates web inputs to reject script-related content that could produce XSS.

SI-15 Information Output Filtering
addresses: CWE-79

Output validation against expected content can reject or sanitize script content in generated web pages, reducing XSS exploitability.

PR.PS-06 mostly match
blocks

Secure SDLC practices directly target injection flaws during coding and review so largely prevent CWE-89 introduction, yet the single broad outcome leaves residual risk from incomplete neutralization techniques or missed edge cases.

PR.AT-02 partial match
blocks

Training raises developer awareness of SQLi risks and can reduce introduction likelihood (partial) but removes none of the actual coding flaw's risk by itself since technical neutralization is still required.

PR.PS-02 partial match
blocks

Patching and EOL replacement can remediate known XSS instances in libraries or frameworks (partial) but do nothing to enforce input neutralization in application code (none).
