  1. CVE-2026-104085 8.8 Élevée

    odt2spip

    odt2spip plugin for SPIP before 4.4.0 contains an OS command injection vulnerability that allows authenticated authors to execute arbitrary commands by uploading a document with a maliciously crafted filename through the document import form. Attackers can embed shell metacharacters such as $(id) in a non-.odt filename, which survives insufficient sanitization in odt2spip_deplacer_fichier_upload() and LibreOffice::createCommand(), to achieve remote code execution as the web-server user during the LibreOffice conversion process.

  2. CVE-2026-109378 4.3 Moyenne

    SPIP

    SPIP before 4.4.18 contains a server-side request forgery vulnerability in recuperer_url() in ecrire/inc/distant.php that follows up to 10 redirects without re-validating targets with valider_url_distante(). Authenticated attackers can supply a remote URL, such as a syndicated site feed or remote document, that redirects to internal or link-local addresses including cloud metadata endpoints.

  3. CVE-2026-104070 9.8 Critique

    SPIP Crayons Plugin

    The Crayons plugin for SPIP before 3.5.0 contains a missing authorization vulnerability that allows unauthenticated attackers to modify arbitrary editable object fields by omitting the secu_ anti-forgery parameter in crayons_store.php, causing the authorization dispatcher to resolve an unconditionally-true handler instead of the proper modification check. Attackers can chain this flaw to write a malicious .html skeleton file, disclose sensitive configuration files containing the site secret, and forge a signed ajax context to execute the uploaded skeleton, achieving arbitrary PHP code execution as the web-server user.
