Title

Twig: PHP code injection via `{% use %}` template name

Summary

Twig is a template language for PHP. Starting in 1.15.1 and prior to 3.26.0, Compiler::string() does not escape single quotes when a template name from a {% use %} tag is placed inside a PHP single-quoted string literal, allowing a crafted template name to terminate the string and inject arbitrary PHP expressions into the compiled cache file. This issue is fixed in version 3.26.0.

Severity

GHSA-7P85-W9PX-JPJP

Vulnerability from github – Published: 2026-05-21 21:24 – Updated: 2026-11-04 00:00

Summary

Twig: PHP code injection via `{% use %}` template name

Details

Description

Compiler::string() escapes ", $, \, NUL and TAB when generating PHP double-quoted string literals, but does not escape single quotes. In ModuleNode::compileConstructor(), the template name from a {% use %} tag is compiled via subcompile() -> string() and placed inside a surrounding PHP single-quoted string literal. A template name containing a single quote terminates that surrounding string early, allowing arbitrary PHP expressions to be injected into the compiled cache file.

The injected code executes within the PHP process when the cache file is first loaded, bypassing the Twig sandbox entirely and achieving remote code execution. SecurityPolicy unconditionally allows {% use %} regardless of the configured allowedTags, so this primitive is reachable from sandboxed templates as well.

Resolution

Compiler::string() now also escapes single quotes so that template names placed inside single-quoted PHP literals can no longer break out of the surrounding context.

Credits

Twig would like to thank Anvil Secure in collaboration with Claude and Anthropic Research for reporting the issue and providing the fix.

How durations are calculated

Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.

Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
