{"id":"CVE-2026-8813","aliases":["GHSA-h64w-w9pr-82m4"],"url":"https://o3.security/vulnerability/CVE-2026-8813","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","published":"2026-05-19T05:00:04.103Z","modified":"2026-08-15T04:07:04.766842745Z","cvss":null,"epss":{"score":0.00522,"percentile":0.42154,"asOf":"2026-08-20"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"exifreader","fixedVersion":"4.39.0"}],"fix":{"url":"https://github.com/mattiasw/ExifReader/commit/c9d88b67e127b2dcc7b46e328df468257fb2dc30","label":"mattiasw/ExifReader@c9d88b6"},"references":[{"type":"WEB","url":"https://gist.github.com/yuki-matsuhashi/3243ea38e5fbf8cfe19b624f04c9f4b4"},{"type":"WEB","url":"https://security.snyk.io/vuln/SNYK-JS-EXIFREADER-16689335"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/8xxx/CVE-2026-8813.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-8813"},{"type":"FIX","url":"https://github.com/mattiasw/ExifReader/commit/c9d88b67e127b2dcc7b46e328df468257fb2dc30"},{"type":"WEB","url":"https://github.com/mattiasw/ExifReader/security/advisories/GHSA-h64w-w9pr-82m4"},{"type":"PACKAGE","url":"https://github.com/mattiasw/ExifReader"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-15T04:07:04.766842745Z"}}
