GHSA-7p85-w9px-jpjp: twig/twig (CVE-2026-46633)

Package	Ecosystem	Affected	Fixed in
twig/twig	Packagist	>=1.15.1, <3.26.0	3.26.0

Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Twig (twig/twig, Packagist) versions before 3.26.0 are affected. A template name in a {% use %} tag can contain a single quote that breaks out of a PHP string in the compiled cache file, so a template author who can supply that name can inject PHP code that runs when the cache file is loaded, even inside the Twig sandbox because {% use %} is always allowed. Upgrade to twig/twig 3.26.0, which escapes single quotes in compiled string literals.
