SPIP < 4.4.8 Cross-Site Scripting via Iframe Tags in Private Area

SPIP before 4.4.8 allows cross-site scripting (XSS) in the private area via malicious iframe tags. The application does not properly sandbox or escape iframe content in the back-office, allowing an attacker to inject and execute malicious scripts. The fix adds a sandbox attribute to iframe tags in the private area. This vulnerability is not mitigated by the SPIP security screen.

SPIP < 4.4.9 Blind Server-Side Request Forgery via Syndicated Sites

SPIP before 4.4.9 allows Blind Server-Side Request Forgery (SSRF) via syndicated sites in the private area. When editing a syndicated site, the application does not verify that the syndication URL is a valid remote URL, allowing an authenticated attacker to make the server issue requests to arbitrary internal or external destinations. This vulnerability is not mitigated by the SPIP security screen.

SPIP < 4.4.9 Cross-Site Scripting in Private Area (Incomplete Fix)

SPIP before 4.4.9 allows Cross-Site Scripting (XSS) in the private area, complementing an incomplete fix from SPIP 4.4.8. The echappe_anti_xss() function was not systematically applied to input, form, button, and anchor (a) HTML tags, allowing an attacker to inject malicious scripts through these elements. This vulnerability is not mitigated by the SPIP security screen.

SPIP < 4.4.9 Insecure Deserialization

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.

SPIP interface_traduction_objets < 2.2.2 Authenticated SQL Injection

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.

SPIP jeux < 4.1.1 Reflected XSS via index Parameters

The SPIP jeux plugin versions prior to 4.1.1 contain a reflected cross-site scripting (XSS) vulnerability in the pre_propre pipeline. The plugin incorporates untrusted request parameters into HTML output without proper output encoding, allowing attackers to inject arbitrary script content into pages that render a jeux block. When a victim is induced to visit a crafted URL, the injected content is reflected into the response and executed in the victim's browser context.

SPIP interface_traduction_objets < 2.2.2 Authenticated RCE

The SPIP interface_traduction_objets plugin versions prior to 2.2.2 contain an authenticated remote code execution vulnerability in the translation interface workflow. The plugin incorporates untrusted request data into a hidden form field that is rendered without SPIP output filtering. Because fields prefixed with an underscore bypass protection mechanisms and the hidden content is rendered with filtering disabled, an authenticated attacker with editor-level privileges can inject crafted content that is evaluated through SPIP's template processing chain, resulting in execution of code in the context of the web server.

SPIP < 4.4.10 SQL Injection RCE via Union & PHP Tags

SPIP versions prior to 4.4.10 contain a SQL injection vulnerability that allows authenticated low-privilege users to execute arbitrary SQL queries by manipulating union-based injection techniques. Attackers can exploit this SQL injection flaw combined with PHP tag processing to achieve remote code execution on the server.

SPIP < 4.4.10 Authentication Bypass via PHP Type Juggling

SPIP versions prior to 4.4.10 contain an authentication bypass vulnerability caused by PHP type juggling that allows unauthenticated attackers to access protected information. Attackers can exploit loose type comparisons in authentication logic to bypass login verification and retrieve sensitive internal data.

Cross-site scripting (XSS) vulnerability in SPIP 1.8.2 and earlier allows remote attackers to inject arbitrary web script or HTML via unspecified parameters to (1) spip_login.php3 and (2) spip_pass.php3.

Cross-site scripting (XSS) vulnerability in recherche.php3 in SPIP 1.8.2-g allows remote attackers to inject arbitrary web script or HTML via the recherche parameter.

SQL injection vulnerability in spip_acces_doc.php3 in SPIP 1.8.2g and earlier allows remote attackers to execute arbitrary SQL commands via the file parameter.

Cross-site scripting (XSS) vulnerability in index.php3 in SPIP 1.8.2-e and earlier and 1.9 Alpha 2 (5539) and earlier allows remote attackers to inject arbitrary web script or HTML via the lang parameter.

Directory traversal vulnerability in Spip_RSS.PHP in SPIP 1.8.2g and earlier allows remote attackers to read or include arbitrary files via ".." sequences in the GLOBALS[type_urls] parameter, which could then be used to execute arbitrary code via resultant direct static code injection in the file parameter to spip_acces_doc.php3.

SPIP 1.8.2-e and earlier and 1.9 Alpha 2 (5539) and earlier allows remote attackers to obtain sensitive information via a direct request to inc-messforum.php3, which reveals the path in an error message.

Multiple SQL injection vulnerabilities in formulaires/inc-formulaire_forum.php3 in SPIP 1.8.2-e and earlier and 1.9 Alpha 2 (5539) and earlier allow remote attackers to execute arbitrary SQL commands via the (1) id_forum, (2) id_article, or (3) id_breve parameters to forum.php3; (4) unspecified vectors related to "session handling"; and (5) when posting "petitions".

PHP remote file inclusion vulnerability in spip_login.php3 in SPIP 1.8.3 allows remote attackers to execute arbitrary PHP code via a URL in the url parameter.

SPIP porte_plume Plugin Arbitrary PHP Execution

The porte_plume plugin used by SPIP before 4.30-alpha2, 4.2.13, and 4.1.16 is vulnerable to an arbitrary code execution vulnerability. A remote and unauthenticated attacker can execute arbitrary PHP as the SPIP user by sending a crafted HTTP request.

Spip 4.1.10 Admin Account Spoofing via Malicious SVG Upload

Spip 4.1.10 contains a file upload vulnerability that allows attackers to upload malicious SVG files with embedded external links. Attackers can trick administrators into clicking a crafted SVG logo that redirects to a potentially dangerous URL through improper file upload filtering.

SPIP < 4.4.5 Open Redirect via Login Form

SPIP before 4.4.5 and 4.3.9 allows an Open Redirect via the login form when used in AJAX mode. An attacker can craft a malicious URL that, when visited by a victim, redirects them to an arbitrary external site after login. This vulnerability only affects sites where the login page has been overridden to function in AJAX mode. It is not mitigated by the SPIP security screen.
