CVE-2026-22206
Published: 26 February 2026
Summary
CVE-2026-22206 is a high-severity SQL Injection (CWE-89) vulnerability in Spip Spip. Its CVSS base score is 8.7 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 42.2th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-2 (Flaw Remediation).
Deeper analysis
SPIP versions prior to 4.4.10 are affected by CVE-2026-22206, a SQL injection vulnerability (CWE-89) that enables authenticated low-privilege users to execute arbitrary SQL queries through union-based injection techniques. This flaw, published on 2026-02-26, carries a CVSS v3.1 base score of 8.8 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H). The vulnerability arises in the context of SPIP, an open-source content management system, and can be chained with PHP tag processing to escalate to remote code execution on the server.
Low-privilege authenticated users, such as contributors or authors with minimal permissions, can exploit this vulnerability over the network with low complexity and no user interaction required. Successful exploitation allows attackers to execute arbitrary SQL queries, potentially extracting sensitive data, modifying database contents, or achieving full remote code execution by leveraging PHP tag processing mechanisms.
Advisories recommend updating to SPIP 4.4.10, as detailed in the official SPIP security blog post announcing the release. The SPIP Git repository provides the patched source code, while the VulnCheck advisory elaborates on the SQL injection leading to RCE via union-based techniques and PHP tags.

Why these techniques?
SQL injection in public-facing SPIP CMS (T1190) allows low-privilege authenticated users to execute arbitrary SQL for data collection from databases (T1213.006) and chain to RCE for privilege escalation (T1068).
