Summary

CVE-2026-27747 is a high-severity SQL Injection (CWE-89) vulnerability in Spip Interface Traduction Objets. Its CVSS base score is 8.8 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 14.0th 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 RA-5 (Vulnerability Monitoring and Scanning) and SI-10 (Information Input Validation).

Threat & Defense at a Glance

What attackers do: exploitation maps to Exploit Public-Facing Application (T1190) and 1 other technique. What defenders deploy: see the NIST 800-53 controls recommended below.

Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

SI-10 Information Input Validation good match

prevent

SI-10 directly prevents SQL injection by requiring validation and sanitization of user-supplied inputs like the id_parent parameter before concatenation into SQL queries.

SI-2 Flaw Remediation good match

prevent

SI-2 ensures timely patching of known flaws, such as updating the SPIP interface_traduction_objets plugin to version 2.2.2 to remediate the SQL injection vulnerability.

RA-5 Vulnerability Monitoring and Scanning good match

detect

RA-5 requires vulnerability scanning that identifies SQL injection flaws like CVE-2026-27747 in plugins, enabling proactive remediation.

Why these techniques?

Authenticated SQL injection in SPIP CMS plugin directly enables T1190 (exploiting the public-facing web app with crafted id_parent input) and facilitates T1213.006 (arbitrary database queries for data collection/modification).

NVD Description

The SPIP interface_traduction_objets plugin versions prior to 2.2.2 contain an authenticated SQL injection vulnerability in interface_traduction_objets_pipelines.php. When handling translation requests, the plugin reads the id_parent parameter from user-supplied input and concatenates it directly into a SQL WHERE clause in a…

call to sql_getfetsel() without input validation or parameterization. An authenticated attacker with editor-level privileges can inject crafted SQL expressions into the id_parent parameter to manipulate the backend query. Successful exploitation can result in disclosure or modification of database contents and may lead to denial of service depending on the database configuration and privileges.

Deeper analysisAI

CVE-2026-27747 is an authenticated SQL injection vulnerability affecting the SPIP interface_traduction_objets plugin in versions prior to 2.2.2. The flaw resides in the interface_traduction_objets_pipelines.php file, where the plugin processes translation requests by reading the id_parent parameter from user-supplied input and directly concatenating it into a SQL WHERE clause within a sql_getfetsel() function call, without any input validation or parameterization. This violates CWE-89 (SQL Injection) and 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).

An authenticated attacker with editor-level privileges can exploit this vulnerability by injecting crafted SQL expressions into the id_parent parameter during translation requests. Successful exploitation allows manipulation of the backend SQL query, potentially resulting in the disclosure or modification of database contents. Depending on the database configuration and attacker privileges, it may also lead to denial of service.

Advisories recommend updating the interface_traduction_objets plugin to version 2.2.2 or later to mitigate the issue, as detailed in the SPIP security blog post announcing SPIP 4.4.10, the plugin's git commit db3417b7811774f04c3ff191ca1737fe660ef0be implementing the fix, and analyses from VulnCheck and Chocapikk. The plugin page on plugins.spip.net provides download access for patched versions.
