Detailsinfo

A vulnerability classified as critical has been found in SPIP up to 4.4.13. Affected is some unknown processing. The manipulation with an unknown input leads to a code injection vulnerability. CWE is classifying the issue as CWE-94. The product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

SPIP versions prior to 4.4.14 contain a remote code execution vulnerability in the private space that allows attackers to execute arbitrary code in the context of the web server. Attackers can exploit this vulnerability to achieve code execution that bypasses the SPIP security screen protections.

The weakness was presented by Louka Jacques-Chevallier. This vulnerability is traded as CVE-2026-8429 since 05/12/2026. The exploitability is told to be easy. It is possible to launch the attack remotely. There are neither technical details nor an exploit publicly available. The MITRE ATT&CK project declares the attack technique as T1059.

The vulnerability scanner Nessus provides a plugin with the ID 316828 (Debian dsa-6296 : spip - security update), which helps to determine the existence of the flaw in a target environment.

Upgrading to version 4.4.14 eliminates this vulnerability.
