{"id":"GHSA-h64w-w9pr-82m4","summary":"ExifReader is vulnerable to denial of service via crafted ICC `mluc` tag","details":"### Impact\n\nWhen parsing an image with an embedded ICC profile that contains a crafted `multiLocalizedUnicodeType` (`mluc`) tag, ExifReader can be made to allocate memory proportional to attacker-controlled fields in the tag rather than to\nthe actual size of the input. Processing such an image causes excessive memory consumption and can terminate the host process (out-of-memory).\n\nAny application that calls `ExifReader.load()` on untrusted images, for example, user uploads in a web service, is affected. ICC profiles are carried in JPEG, TIFF, PNG, HEIC, AVIF, JPEG XL, and WebP, so the issue is reachable from any of those formats.\n\n### Patches\n\nFixed in `exifreader@4.39.0`. Upgrade with:\n\n    npm install exifreader@latest\n\nBower users consume the bundled `dist/` files from this repository, and the same fix is committed there.\n\n### Workarounds\n\nIf upgrading is not immediately possible, configure a [custom build](https://github.com/mattiasw/ExifReader#configure-a-custom-build) that excludes the `icc` module so that ICC parsing (and therefore this code path) is skipped entirely.\n\n### Resources\n\n- Patch: https://github.com/mattiasw/ExifReader/commit/c9d88b67e127b2dcc7b46e328df468257fb2dc30","aliases":["CVE-2026-8813"],"modified":"2026-07-17T17:00:52.076721049Z","published":"2026-05-29T17:58:37Z","database_specific":{"github_reviewed":true,"github_reviewed_at":"2026-05-29T17:58:37Z","nvd_published_at":"2026-05-19T07:16:30Z","cwe_ids":["CWE-1284"],"severity":"HIGH"},"references":[{"type":"WEB","url":"https://github.com/mattiasw/ExifReader/security/advisories/GHSA-h64w-w9pr-82m4"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-8813"},{"type":"WEB","url":"https://github.com/mattiasw/ExifReader/commit/c9d88b67e127b2dcc7b46e328df468257fb2dc30"},{"type":"PACKAGE","url":"https://github.com/mattiasw/ExifReader"},{"type":"WEB","url":"https://security.snyk.io/vuln/SNYK-JS-EXIFREADER-16689335"}],"affected":[{"package":{"name":"exifreader","ecosystem":"npm","purl":"pkg:npm/exifreader"},"ranges":[{"type":"SEMVER","events":[{"introduced":"2.10.0"},{"fixed":"4.39.0"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/05/GHSA-h64w-w9pr-82m4/GHSA-h64w-w9pr-82m4.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"},{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:P"}]}
