Name of the Vulnerable Software and Affected Versions php-svg-lib versions prior to 0.5.1

Description The issue arises when handling <use> tags that reference <image> tags, as it merges attributes from the <use> tag to the <image> tag. This is particularly problematic when the href attribute from the <use> tag has not been sanitized, leading to an unsafe file read. This can cause a PHAR Deserialization issue in PHP prior to version 8.

Recommendations For versions prior to 0.5.1, update to version 0.5.1 to resolve the issue. As a temporary workaround, consider sanitizing the href attribute from the <use> tag to prevent unsafe file reads.
