{"id":"CVE-2026-8814","details":"Versions of the package exifreader before 4.39.0 are vulnerable to Improper Handling of Highly Compressed Data (Data Amplification) due to decompressing PNG zTXt metadata without enforcing a built-in maximum decompressed output size. 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.","aliases":["GHSA-rr89-w3h9-m66j"],"modified":"2026-08-12T03:51:30.414814372Z","published":"2026-05-19T05:00:09.223Z","database_specific":{"cwe_ids":["CWE-409"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/8xxx/CVE-2026-8814.json","cna_assigner":"snyk"},"references":[{"type":"WEB","url":"https://gist.github.com/yuki-matsuhashi/cad1a45d936062438b4ab24613c34c55"},{"type":"WEB","url":"https://security.snyk.io/vuln/SNYK-JS-EXIFREADER-16689340"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/8xxx/CVE-2026-8814.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-8814"},{"type":"FIX","url":"https://github.com/mattiasw/ExifReader/commit/5f116128adc19f674902f8bf582bfe7dd0a36375"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/mattiasw/exifreader","events":[{"introduced":"0"},{"fixed":"fa7815bc95a67771244fa00a068718a52c02ca2e"},{"fixed":"5f116128adc19f674902f8bf582bfe7dd0a36375"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"4.39.0"}],"source":["DESCRIPTION","REFERENCES"]}}],"versions":["v4.38.1","v4.38.0","v4.37.1","v4.37.0","v4.36.2","v4.36.1","v4.36.0","v4.35.0","v4.34.0","v4.33.1","v4.33.0","v4.32.0","v4.31.2","v4.31.1","v4.31.0","v4.30.1","v4.30.0","v4.29.0","v4.28.1","v4.28.0","v4.27.0","v4.26.2","v4.26.1","v4.26.0","v4.25.0","v4.24.0","v4.23.7","v4.23.6","v4.23.5","v4.23.4","v4.23.3","v4.23.2","v4.23.1","v4.23.0","v4.22.1","v4.22.0","v4.21.1","v4.21.0","v4.20.0","v4.19.1","v4.19.0","v4.18.0","v4.16.0","v4.15.0","v4.14.1","v4.14.0","4.14.0","4.13.2","4.13.1","v4.13.0","4.13.0","4.12.1","v4.12.0","4.12.0","v4.11.1","4.11.1","v4.11.0","4.11.0","v4.10.0","4.10.0","v4.9.2","4.9.2","v4.9.1","4.9.1","v4.9.0","4.9.0","v4.8.1","4.8.1","v4.8.0","4.8.0","v4.7.0","4.7.0","v4.6.0","4.6.0","v4.5.1","4.5.1","v4.5.0","4.5.0","v4.4.0","4.4.0","v4.3.1","4.3.1","v4.3.0","4.3.0","v4.2.0","4.2.0","v4.1.1","4.1.1","v4.1.0","4.1.0","v4.0.0","4.0.0","v3.16.0","3.16.0","v3.15.0","3.15.0","v3.14.1","3.14.1","v3.14.0","3.14.0","v3.13.0","3.13.0","v3.12.6","3.12.6","v3.12.5","3.12.5","v3.12.4","3.12.4","v3.12.3","3.12.3","v3.12.2","3.12.2","3.12.1","v3.12.0","3.12.0","v3.11.2","3.11.2","v3.11.1","3.11.1","v3.11.0","3.11.0","v3.10.0","3.10.0","v3.9.0","3.9.0","v3.8.0","3.8.0","v3.7.0","3.7.0","v3.6.1","3.6.1","3.6.0","3.4.0","3.3.0","3.2.0","3.1.0","3.0.0","2.13.1","2.13.0","2.12.0","2.11.0","2.10.0","2.9.0","2.8.5","2.8.4","2.8.3","2.8.2","2.8.1","2.7.0","2.6.0","2.5.0","2.4.0","2.3.0","2.2.0","2.1.2","2.1.1","2.1.0","2.0.2","v1.1.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-8814.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"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"}]}
