Summary

Twig is a template language for PHP. Prior to 3.27.0, the column filter passes the active sandbox state as a boolean but does not forward the current Source to SandboxExtension::checkPropertyAllowed(), so SourcePolicyInterface decisions are lost and a template author can read public or magic properties not allowed by the sandbox policy. This issue is fixed in version 3.27.0.

Fencer Vulns keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.

CPEs and fixed versions use Anchore's correction of NVD's data: Added CPE configurations because not yet analyzed by NVD.
