When asynchronous parsing is enabled, a crafted PNG file containing a highly compressed zTXt chunk can cause ExifReader to materialize a disproportionately large Comment value in memory.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:P","score":5.5},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L","score":5.3},"cwes":["CWE-409"],"references":["https://gist.github.com/yuki-matsuhashi/cad1a45d936062438b4ab24613c34c55","https://github.com/mattiasw/ExifReader/commit/5f116128adc19f674902f8bf582bfe7dd0a36375","https://security.snyk.io/vuln/SNYK-JS-EXIFREADER-16689340","https://security.snyk.io/vuln/SNYK-JS-EXIFREADER-16689340"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:35:16.954578616+00:00"},"epss":{"cve":"CVE-2026-8814","score":0.00465,"percentile":0.4028,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-rr89-w3h9-m66j","url":"https://osv.dev/vulnerability/GHSA-rr89-w3h9-m66j","summary":"ExifReader is vulnerable to denial of service via unbounded decompression of image metadata","modified":"2026-07-17T17:00:52.238236387Z","packages":[{"ecosystem":"npm","name":"exifreader","purl":"pkg:npm/exifreader","ranges":[">=4.20.0 <4.39.0"],"fixed":["4.39.0"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
