CVE-2022-41343
Published: 25 September 2022
registerFont in FontMetrics.php in Dompdf before 2.0.1 allows remote file inclusion because a URI validation failure does not halt font registration, as demonstrated by a @font-face rule.
Notes
| Author | Note |
|---|---|
| ccdm94 | the code is not present in version 0.6.2, even though there is a register_font function in include/font_metrics.cls.php which seems to contain similar code as the registerFont function being patched in the fix commit. |
