CVE-2026-27475
Received Received - Intake
Insecure Deserialization in SPIP Public Area Enables Code Execution

Publication date: 2026-02-19

Last updated on: 2026-02-24

Assigner: VulnCheck

Description
SPIP before 4.4.9 allows Insecure Deserialization in the public area through the table_valeur filter and the DATA iterator, which accept serialized data. An attacker who can place malicious serialized content (a pre-condition requiring prior access or another vulnerability) can trigger arbitrary object instantiation and potentially achieve code execution. The use of serialized data in these components has been deprecated and will be removed in SPIP 5. This vulnerability is not mitigated by the SPIP security screen.

Executive Summary

This vulnerability affects SPIP versions before 4.4.9 and involves insecure deserialization in the public area through the table_valeur filter and the DATA iterator, which accept serialized data.

An attacker who can place malicious serialized content (which requires prior access or another vulnerability) can trigger arbitrary object instantiation, potentially leading to code execution.

The use of serialized data in these components has been deprecated and will be removed in SPIP 5.

This vulnerability is not mitigated by the SPIP security screen.

Impact Analysis

If exploited, this vulnerability can allow an attacker to execute arbitrary code on the affected system.
