From 2.0.0 until 4.1.2, ExifReader.ReadValues64 trusts the 64-bit BigTIFF IFD entry count and iterates once per declared entry. When fewer than 20 bytes remain, ExifReader.ReadValue64 returns without advancing the stream or terminating the outer loop, so a small malformed BigTIFF can keep one decoder thread executing for an attacker-controlled duration. This report does not claim worker-pool exhaustion. This issue is fixed in version 4.1.2."}],"affected":[{"source":"security-advisories@github.com","affectedData":[{"vendor":"SixLabors","product":"ImageSharp","versions":[{"version":">= 2.0.0, < 4.1.2","status":"affected"}]}]}],"metrics":{"cvssMetricV31":[{"source":"security-advisories@github.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L","baseScore":5.3,"baseSeverity":"MEDIUM","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"NONE","integrityImpact":"NONE","availabilityImpact":"LOW"},"exploitabilityScore":3.9,"impactScore":1.4}],"ssvcV203":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","ssvcData":{"timestamp":"2026-10-06T18:21:43.778832Z","id":"CVE-2026-106116","options":[{"exploitation":"poc"},{"automatable":"yes"},{"technicalImpact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}]},"weaknesses":[{"source":"security-advisories@github.com","type":"Secondary","description":[{"lang":"en","value":"CWE-835"}]}],"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:a:sixlabors:imagesharp:*:*:*:*:*:*:*:*","versionStartIncluding":"2.0.0","versionEndExcluding":"3.2.0","matchCriteriaId":"FA378490-EF2F-4A3F-B62B-188E95240AC8"},{"vulnerable":true,"criteria":"cpe:2.3:a:sixlabors:imagesharp:*:*:*:*:*:*:*:*","versionStartIncluding":"4.0.0","versionEndExcluding":"4.1.2","matchCriteriaId":"F920B012-BBFB-40DB-B201-165EBA6645D7"}]}]}],"references":[{"url":"https://github.com/SixLabors/ImageSharp/commit/92b12d72550ebb6be5b1e22e559c361fd863a6ec","source":"security-advisories@github.com","tags":["Patch"]},{"url":"https://github.com/SixLabors/ImageSharp/pull/3187","source":"security-advisories@github.com","tags":["Issue Tracking","Patch"]},{"url":"https://github.com/SixLabors/ImageSharp/releases/tag/v4.1.2","source":"security-advisories@github.com","tags":["Release Notes"]},{"url":"https://github.com/SixLabors/ImageSharp/security/advisories/GHSA-wmxv-xphr-5c9g","source":"security-advisories@github.com","tags":["Exploit","Vendor Advisory"]},{"url":"https://github.com/SixLabors/ImageSharp/security/advisories/GHSA-wmxv-xphr-5c9g","source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","tags":["Exploit","Vendor Advisory"]}]}
