Project: Digital Signage Framework [1]
Date: 2026-August-26
Security risk: *Moderately critical* 13 ∕ 25
AC:Basic/A:None/CI:Some/II:None/E:Theoretical/TD:All [2]
Vulnerability: Access bypass

Affected versions: <2.6.1
CVE IDs: CVE-2026-81166
Description: 
The Digital Signage Framework module provides a route that signage devices
can call to refresh dynamic blocks on a display.

The route did not check whether the requester was a signage device, nor
whether the requested block was one that the module delivers to displays. As
a result, an anonymous visitor could read the rendered content of blocks they
were not meant to see.

This vulnerability is mitigated by the fact that many block plugins perform
their own access checks on the content they display, which limits what can be
disclosed through this route.

Solution: 
Install the latest version:

 * If you use Digital Signage Framework 2.6.x, update to 2.6.1 [3].

 * Marcus Johansson (marcus_johansson) [4]
