TYPO3 CMS - Open Redirect in Core Utilities

Applications that use GeneralUtility::sanitizeLocalUrl to allow only local URLs are vulnerable to open redirect attacks if the URL is used after it has passed the aforementioned sanitization checks. This enables attackers to redirect users to external content and carry out phishing attacks. This issue affects TYPO3 CMS versions before 10.4.57, 11.0.0-11.5.50, 12.0.0-12.4.45, 13.0.0-13.4.30 and 14.0.0-14.3.2.

TYPO3 CMS - Broken Access Control in Clipboard

Backend users were able to insert arbitrary records and files into the TYPO3 clipboard without proper read permission checks, which allowed users to gather information about records and files they were not authorized to view. This issue affects TYPO3 CMS versions 10.4.0-13.4.30 and 14.0.0-14.3.2.

TYPO3 CMS - Broken Access Control in Media Module

Backend users with file download permissions were able to download files from the fallback storage of the file abstraction layer (FAL) via the Media Module. Since the fallback storage resolves paths relative to the server's document root, this could expose sensitive files such as log files. This issue affects TYPO3 CMS versions 11.0.0-11.5.50, 12.0.0-12.4.45, 13.0.0-13.4.30 and 14.0.0-14.3.2.

TYPO3 CMS - Destructive Actions on File Mount Folders

Non-privileged backend users with file mount access were able to perform write operations (move, delete, rename) on folders representing the root of an active file mount due to missing authorization restrictions. This issue affects TYPO3 CMS versions before 10.4.57, 11.0.0 through 11.5.50, 12.0.0 through 12.4.45, 13.0.0 through 13.4.30, and 14.0.0 through 14.3.2.

TYPO3 CMS - Broken Access Control in Form Framework

Backend users with file write permissions were able to upload form definition files with mixed-case extensions (e.g., .FORM.YAML) to bypass the Form Framework's upload restriction. Maliciously crafted form definition files can be used to execute arbitrary SQL statements, allowing attackers to escalate privileges by creating administrative backend user accounts. This issue affects TYPO3 CMS versions before 10.4.57, 11.0.0-11.5.50, 12.0.0-12.4.45, 13.0.0-13.4.30 and 14.0.0-14.3.2.

TYPO3 HTML Sanitizer allows Cross-Site Scripting

Namespace attributes are not encoded correctly during HTML serialization. This allows bypassing the cross-site scripting prevention mechanism of typo3/html-sanitizer before version 2.3.2.

TYPO3 HTML Sanitizer allows Cross-Site Scripting

When ALLOW_INSECURE_RAW_TEXT is enabled, whitespace-variant closing tags (e.g., </style\t>) are not recognized by the sanitizer but accepted by browsers as valid end tags, allowing subsequent content to escape sanitization. This allows bypassing the cross-site scripting prevention mechanism of typo3/html-sanitizer before version 2.3.2.

Remote Code Execution in extension "Site Crawler" (crawler)

The Crawler extension passes the X-T3Crawler-Meta response header from crawled URLs directly to PHP's unserialize(). An attacker controlling a crawled endpoint can inject arbitrary serialized PHP objects, leading to Remote Code Execution on the TYPO3 server. Exploitation requires administrative privileges to configure a crawler-enabled page and trigger the crawl via a Scheduler task.

Broken Access Control in extension "Frontend User Registration" (sf_register)

The create and edit flows do not restrict which user properties may be submitted and do not enforce access control on the frontend user group assignment. As a result, an attacker can assign an arbitrary frontend user group to a newly registered or edited account, gaining unauthorized access to content and functionality restricted to privileged frontend user groups.

SQL Injection in extension "News system" (news)

The extension fails to properly sanitize user input before using it in a database query. As a result, an unauthenticated attacker can inject arbitrary SQL through a URL parameter on pages using the "Date Menu of news articles" plugin. Exploitation requires the "Date Menu of news articles" plugin to be in use and the TypoScript/Plugin setting disableOverrideDemand not to be enabled.

XML External Entity Injection in extension "Faceted Search" (ke_search)

The OOXML parsing of the file indexer does not disable external entity resolution. A crafted xlsx or pptx document placed in an indexed directory can cause local files to be read or outbound HTTP requests to be performed, with the retrieved content being written to the search index.

Information Disclosure in extension "Faceted Search" (ke_search)

The additional_tables configuration of the page and tt_content indexers accepts arbitrary table and field names. A backend user with permission to edit indexer configurations can copy sensitive data from internal TYPO3 tables into the search index.

Path Traversal in extension "Faceted Search" (ke_search)

The file indexer does not normalize the configured directory path. A backend user with permission to edit indexer configurations can index documents from arbitrary locations on the server file system through path traversal sequences.

SQL Injection in extension "Address List" (tt_address)

The AddressRepository::getSqlQuery() method constructs a database query without properly sanitizing user input, leading to SQL Injection. The method is not invoked anywhere within the extension itself and therefore poses no direct risk in a default installation. However, custom extensions that call this method with untrusted input would expose the site to SQL injection.

Remote Code Execution in extension "Content Element Selector" (ceselector)

The extension passes an attacker-controlled cookie directly to PHP's unserialize() without safely processing the input. A remote, unauthenticated attacker can supply a crafted serialized payload to trigger PHP Object Injection, leading to Remote Code Execution on the TYPO3 server. Exploitation requires the content element to be configured with "Persistent Mode: Static" in the plugin settings.

TYPO3 CMS Stores Cleartext Password in User Settings Module

Changing backend users' passwords via the user settings module results in storing the cleartext password in the uc and user_settings fields of the be_users database table. This issue affects TYPO3 CMS version 14.2.0.

Authentication Bypass in extension "E-Mail MFA Provider" (mfa_email)

The extension fails to properly reset the generated MFA code after successful authentication. This leads to a possible MFA bypass for future login attempts by providing an empty string as MFA code to the extensions MFA provider.

Broken Access Control in extension "Redirect Tab"

The extension fails to verify, if an authenticated user has permissions to access to redirects resulting in exposure of redirect records when editing a page.

Insecure Deserialization in extension "Mailqueue" (mailqueue)

The extension fails to properly define allowed classes used when deserializing transport failure metadata. An attacker may exploit this to execute untrusted serialized code. Note that an active exploit requires write access to the directory configured at $GLOBALS['TYPO3_CONF_VARS']['MAIL']['transport_spool_filepath'].

SQL injection vulnerability in the WEBERkommunal Facilities (wes_facilities) extension 2.0 for TYPO3 allows remote attackers to execute arbitrary SQL commands via unspecified vectors.
