GHSA-v383-3rw5-q8rf: enshrined/svg-sanitize (CVE-2026-107379)

Package	Ecosystem	Affected	Fixed in
enshrined/svg-sanitize	Packagist	<1.0.0	1.0.0

Machine-written summary

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

The enshrined/svg-sanitize PHP package, versions before 1.0.0, crashes the PHP process when it sanitizes a specially crafted SVG file that includes a DTD attribute declaration. An attacker who can get such a file processed, for example by uploading it through an application that uses the sanitizer, can cause a denial of service by killing PHP workers. The fix is to upgrade to version 1.0.0.
