silverstripe/framework is vulnerable to Remote Code Execution (RCE)
72
High Risk
This Affects:
silverstripe/frameworkTL;DR
The silverstripe/framework template compiler emits the default and context strings of a <%t %> translation block directly into the generated PHP template. Before the fix, SSTemplateParser pasted these author-controlled strings in verbatim as double-quoted literals, so a string containing PHP interpolation such as {${'shell_exec'('id')}} was evaluated when the compiled template ran. This allows arbitrary PHP to execute on the server wherever an attacker can influence a translation default or context string. The fix re-emits the value as a single-quoted PHP literal so it is treated as inert text.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range and your project renders <%t %> translation default or context strings that can contain attacker-influenced content.
