GHSA-36g8-62qv-5957
TYPO3 vulnerable to an Uncontrolled Resource Consumption in the ShowImageController
Quick fix
GHSA-36g8-62qv-5957 — typo3/cms-core: upgrade to the fixed version with the command below.
composer require typo3/cms-core:^9.5.48Details
### Problem The `ShowImageController` (_eID tx_cms_showpic_) lacks a cryptographic HMAC-signature on the `frame` HTTP query parameter (e.g. `/index.php?eID=tx_cms_showpic?file=3&...&frame=12345`). This allows adversaries to instruct the system to produce an arbitrary number of thumbnail images on the server side.
### Solution Update to TYPO3 versions 9.5.48 ELTS, 10.4.45 ELTS, 11.5.37 LTS, 12.4.15 LTS, 13.1.1 that fix the problem described.
#### ℹ️ **Strong security defaults - Manual actions required**
The `frame` HTTP query parameter is now ignored, since it could not be used by core APIs.
The new feature flag `security.frontend.allowInsecureFrameOptionInShowImageController` – which is disabled per default – can be used to reactivate the previous behavior.
### Credits Thanks to TYPO3 security team member Torben Hansen who reported this issue and to TYPO3 core & security team members Benjamin Mack and Benjamin Franzke who fixed the issue.
