typo3/cms-core
source listedECOSYSTEM: introduced 9.0.0; fixed 9.5.48
### 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. ### References * TYPO3-CORE-SA-2024-010

A fixed release is not deployment evidence.
Check current vendor support and compatibility. After making a change, verify the deployed build and relevant runtime conditions. Keep the evidence, owner and time. An updated lockfile alone does not prove what is running.
