Name of the Vulnerable Software and Affected Versions blurhash-rs version 0.1.1

Description The blurhash parsing code may panic due to multiple panic-guarded out-of-bounds accesses on untrusted input. In a typical deployment, this may get triggered by feeding maliciously crafted blurhashes over the network, including UTF-8 compliant strings containing multi-byte UTF-8 characters.

Recommendations For version 0.1.1, update to version 0.2.0, which includes a patch for this issue, noting that it may require user intervention due to slight API churn. As a temporary workaround, consider restricting the input of blurhashes to trusted sources until the update can be applied.
