Detailsinfo

A vulnerability, which was classified as critical, has been found in SPIP tickets up to 4.3.2. Affected by this issue is an unknown functionality. The manipulation with an unknown input leads to a code injection vulnerability. Using CWE to declare the problem leads to 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. Impacted is confidentiality, integrity, and availability. CVE summarizes:

The SPIP tickets plugin versions prior to 4.3.3 contain an unauthenticated remote code execution vulnerability in the forum preview handling for public ticket pages. The plugin appends untrusted request parameters into HTML that is later rendered by a template using unfiltered environment rendering (#ENV**), which disables SPIP output filtering. As a result, an unauthenticated attacker can inject crafted content that is evaluated through SPIP's template processing chain, leading to execution of code in the context of the web server.

The weakness was released by Valentin Lobstein. This vulnerability is handled as CVE-2026-27744 since 02/23/2026. The exploitation is known to be easy. The attack may be launched remotely. No form of authentication is required for exploitation. The technical details are unknown and an exploit is not available. This vulnerability is assigned to T1059 by the MITRE ATT&CK project.

Upgrading to version 4.3.3 eliminates this vulnerability. Applying the patch 869935b6687822ed79ad5477626a664d8ea6dcf7 is able to eliminate this problem. The bugfix is ready for download at git.spip.net. The best possible mitigation is suggested to be upgrading to the latest version.
