SCA: security update for contao/contao, contao/core-bundle (GHSA-87mg-5grr-rhwh)

low Tenable Cloud Security Plugin ID 448343

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Contao is an Open Source CMS. From 5.3.35 through 5.3.47 and from 5.7.0-RC1 through 5.7.8, the Feed Reader
 front-end module passes configured RSS feed URLs from FeedReaderController::getResponse() to
 feedIo->read() without scheme or private-address validation, allowing a backend user with module-edit
 permissions to make the server request internal network services, loopback addresses, or cloud metadata
 endpoints. In core-bundle/src/Controller/FrontendModule/FeedReaderController.php, the getResponse()
 function iterates over the configured feed URLs and passes each one directly to the HTTP client (via
 $this->feedIo->read($url, new Feed())) with no validation, while the DCA field definition for rss_feed in
 tl_module.php carries no URL scheme or host validation and the HTTP client is wired as @psr18.http_client
 (Symfony HttpClient) with no SSRF protection configured, since NoPrivateNetworkHttpClient is not used.
 This issue is fixed in versions 5.3.48. (CVE-2026-57232)

Solution

Update the contao/contao library and its related packages to version 5.3.48 or later.
