In version 0.1.1, 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 a maliciously crafted blurhashes over the network. These may include UTF-8 compliant strings containing multi-byte UTF-8 characters. A patch is available in version 0.2.0, which requires user intervention because of slight API churn. No known workarounds are available.","state":0,"publishedAt":"2023-09-19T15:15:57.27+00:00","modifiedAt":"2026-06-17T06:23:50.947+00:00","affected":[],"metrics":[{"system":"CVSS 3.1 · security-advisories@github.com · Secondary","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:N/A:H","score":8.6,"severity":"HIGH"},{"system":"CVSS 3.1 · nvd@nist.gov · Primary","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5,"severity":"HIGH"}],"references":["https://github.com/whisperfish/blurhash-rs/security/advisories/GHSA-cxvp-82cq-57h2"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2023-42447","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Modified","weaknesses":["CWE-248","CWE-392","CWE-1284"],"productCriteria":["cpe:2.3:a:whisperfish:blurhash-rs:0.1.1:*:*:*:*:rust:*:*"],"sourceDates":{"published":"2023-09-19T15:15:57.270","lastModified":"2026-06-17T06:23:50.947"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
