TYPO3 is an open source web content management system. Prior to versions 7.6.57 ELTS, 8.7.47 ELTS, 9.5.34 ELTS, 10.4.29, and 11.5.11, system internal credentials or keys (e.g. database credentials) can be logged as plaintext in exception handlers, when logging the complete exception stack trace. TYPO3 versions 7.6.57 ELTS, 8.7.47 ELTS, 9.5.34 ELTS, 10.4.29, 11.5.11 contain a fix for the problem.

TYPO3 is an open source web content management system. Prior to versions 7.6.57 ELTS, 8.7.47 ELTS, 9.5.34 ELTS, 10.4.29, and 11.5.11, the export functionality fails to limit the result set to allowed columns of a particular database table. This way, authenticated users can export internal details of database tables they already have access to. TYPO3 versions 7.6.57 ELTS, 8.7.47 ELTS, 9.5.34 ELTS, 10.4.29, 11.5.11 fix the problem described above. In order to address this issue, access to mentioned export functionality is completely denied for regular backend users.

TYPO3 is an open source PHP based web content management system released under the GNU GPL. It has been discovered that the new TYPO3 v11 feature that allows users to create and share deep links in the backend user interface is vulnerable to cross-site-request-forgery. The impact is the same as described in TYPO3-CORE-SA-2020-006 (CVE-2020-11069). However, it is not limited to the same site context and does not require the attacker to be authenticated. In a worst case scenario, the attacker could create a new admin user account to compromise the system. To successfully carry out an attack, an attacker must trick his victim to access a compromised system. The victim must have an active session in the TYPO3 backend at that time. The following Same-Site cookie settings in $GLOBALS[TYPO3_CONF_VARS][BE][cookieSameSite] are required for an attack to be successful: SameSite=strict: malicious evil.example.org invoking TYPO3 application at good.example.org and SameSite=lax or none: malicious e…

TYPO3 is an open source PHP based web content management system released under the GNU GPL. It has been discovered that TYPO3 CMS is susceptible to host spoofing due to improper validation of the HTTP Host header. TYPO3 uses the HTTP Host header, for example, to generate absolute URLs during the frontend rendering process. Since the host header itself is provided by the client, it can be forged to any value, even in a name-based virtual hosts environment. This vulnerability is the same as described in TYPO3-CORE-SA-2014-001 (CVE-2014-3941). A regression, introduced during TYPO3 v11 development, led to this situation. The already existing setting $GLOBALS['TYPO3_CONF_VARS']['SYS']['trustedHostsPattern'] (used as an effective mitigation strategy in previous TYPO3 versions) was not evaluated anymore, and reintroduced the vulnerability.

TYPO3 is an open source PHP based web content management system released under the GNU GPL. In affected versions failing to properly parse, sanitize and encode malicious rich-text content, the content rendering process in the website frontend is vulnerable to cross-site scripting. Corresponding rendering instructions via TypoScript functionality HTMLparser does not consider all potentially malicious HTML tag & attribute combinations per default. In default scenarios, a valid backend user account is needed to exploit this vulnerability. In case custom plugins used in the website frontend accept and reflect rich-text content submitted by users, no authentication is required. Update to TYPO3 versions 7.6.53 ELTS, 8.7.42 ELTS, 9.5.29, 10.4.19, 11.3.2 that fix the problem described.

TYPO3 is an open source PHP based web content management system. Versions 9.0.0 through 9.5.28, 10.0.0 through 10.4.17, and 11.0.0 through 11.3.0 have a cross-site scripting vulnerability. When settings for _backend layouts_ are not properly encoded, the corresponding grid view is vulnerable to persistent cross-site scripting. A valid backend user account is needed to exploit this vulnerability. TYPO3 versions 9.5.29, 10.4.18, 11.3.1 contain a patch for this vulnerability.

TYPO3 is an open source PHP based web content management system. In versions 9.0.0 through 9.5.27, 10.0.0 through 10.4.17, and 11.0.0 through 11.3.0, user credentials may been logged as plain-text. This occurs when explicitly using log level debug, which is not the default configuration. TYPO3 versions 9.5.28, 10.4.18, 11.3.1 contain a patch for this vulnerability.

TYPO3 is an open source PHP based web content management system. Versions 9.0.0 through 9.5.28, 10.0.0 through 10.4.17, and 11.0.0 through 11.3.0 have a cross-site scripting vulnerability. When _Page TSconfig_ settings are not properly encoded, corresponding page preview module (_Web>View_) is vulnerable to persistent cross-site scripting. A valid backend user account is needed to exploit this vulnerability. TYPO3 versions 9.5.29, 10.4.18, 11.3.1 contain a patch for this issue.

TYPO3 is an open source PHP based web content management system. Versions 9.0.0 through 9.5.28, 10.0.0 through 10.4.17, and 11.0.0 through 11.3.0 have a cross-site scripting vulnerability. When error messages are not properly encoded, the components _QueryGenerator_ and _QueryView_ are vulnerable to both reflected and persistent cross-site scripting. A valid backend user account having administrator privileges is needed to exploit this vulnerability. TYPO3 versions 9.5.29, 10.4.18, 11.3.1 contain a patch for this issue.

Bootstrap Package is a theme for TYPO3. It has been discovered that rendering content in the website frontend is vulnerable to cross-site scripting. A valid backend user account is needed to exploit this vulnerability. Users of the extension, who have overwritten the affected templates with custom code must manually apply the security fix. Update to version 7.1.2, 8.0.8, 9.1.4, 10.0.10 or 11.0.3 of the Bootstrap Package that fix the problem described. Updated version are available from the TYPO3 extension manager, Packagist and at https://extensions.typo3.org/extension/download/bootstrap_package/.
