{"id":"CVE-2026-106111","summary":"ImageSharp: EXR ZIP decoder can expose stale allocator data after a short inflate","details":"ImageSharp is a 2D graphics library. From 4.0.0 until 4.1.2, ExrBaseDecompressor.UndoZipCompression accepts a nonempty ZIP or ZIPS inflate result that is shorter than the EXR block's required size. ZipExrCompression.Decompress reconstructs the returned prefix while ExrDecoderCore processes the full expected block from a buffer obtained through Configuration.Default, allowing bytes retained from a completed prior ImageSharp operation to appear in decoded pixels. Applications that expose pixels or output from the later attacker-controlled EXR decode can disclose process-local image data. This issue is fixed in version 4.1.2.","aliases":["GHSA-4q3p-rj5x-xv7p"],"modified":"2026-10-22T10:36:22.372789585Z","published":"2026-10-06T17:44:24.782Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-226"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/106xxx/CVE-2026-106111.json"},"references":[{"type":"WEB","url":"https://github.com/SixLabors/ImageSharp/releases/tag/v4.1.2"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/106xxx/CVE-2026-106111.json"},{"type":"ADVISORY","url":"https://github.com/SixLabors/ImageSharp/security/advisories/GHSA-4q3p-rj5x-xv7p"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-106111"},{"type":"FIX","url":"https://github.com/SixLabors/ImageSharp/commit/3c43cf583fdd98eff0f451397affaa31c6a2e6b1"},{"type":"FIX","url":"https://github.com/SixLabors/ImageSharp/commit/6ed2a275217d39301e76df42acec2a9533b39d2b"},{"type":"FIX","url":"https://github.com/SixLabors/ImageSharp/pull/3187"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/sixlabors/imagesharp","events":[{"introduced":"ff36e83c740e8049574eb468798151e96a176f12"},{"fixed":"dee414097e4be7bb35ef0209cf96bd0b61a7133a"},{"fixed":"3c43cf583fdd98eff0f451397affaa31c6a2e6b1"},{"fixed":"6ed2a275217d39301e76df42acec2a9533b39d2b"}],"database_specific":{"extracted_events":[{"strategy":"StringRangeExpression","range":[{"introduced":"4.0.0"},{"fixed":"4.1.2"}],"source":"AFFECTED_FIELD"},{"source":"REFERENCES_COMMIT","range":[{"fixed":"3c43cf583fdd98eff0f451397affaa31c6a2e6b1"}]},{"range":[{"fixed":"6ed2a275217d39301e76df42acec2a9533b39d2b"}],"source":"REFERENCES_COMMIT"},{"source":"REFERENCES_TAG","original_tag":"v4.1.2","range":[{"fixed":"dee414097e4be7bb35ef0209cf96bd0b61a7133a"}]}]}}],"versions":["v4.1.1","v4.1.0","v4.0.0"],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-106111.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N"}]}
