{"id":"CVE-2023-42447","aliases":["GHSA-cxvp-82cq-57h2","RUSTSEC-2023-0083"],"url":"https://o3.security/vulnerability/CVE-2023-42447","summary":"blurhash panics on parsing crafted inputs","details":"blurhash-rs is a pure Rust implementation of Blurhash, software for encoding images into ASCII strings that can be turned into a gradient of colors representing the original image. 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.","published":"2023-09-19T14:57:16.784Z","modified":"2026-10-28T02:30:54.103710210Z","cvss":{"score":8.6,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:N/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"crates.io","name":"blurhash","fixedVersion":"0.2.0"}],"fix":null,"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/42xxx/CVE-2023-42447.json"},{"type":"ADVISORY","url":"https://github.com/whisperfish/blurhash-rs/security/advisories/GHSA-cxvp-82cq-57h2"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-42447"},{"type":"PACKAGE","url":"https://github.com/whisperfish/blurhash-rs"},{"type":"WEB","url":"https://github.com/whisperfish/blurhash-rs/releases/tag/v0.2.0"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-10-28T02:30:54.103710210Z"}}
