From 1.3.0 until 9.0.0, ZipArchive::extract in src/read/mod.rs calls Vec::with_capacity for a symbolic link target using the attacker-controlled ZIP64 uncompressed_size before reading entry data. A small archive can request an impossible capacity, causing the infallible allocation path to abort the process before the entry is validated. The failure cannot be contained with catch_unwind or a worker thread, allowing repeated denial of service in archive-processing applications. This issue is fixed in version 9.0.0."}],"affected":[{"source":"security-advisories@github.com","affectedData":[{"vendor":"zip-rs","product":"zip2","versions":[{"version":">= 1.3.0, < 9.0.0","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:H","baseScore":7.5,"baseSeverity":"HIGH","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"NONE","integrityImpact":"NONE","availabilityImpact":"HIGH"},"exploitabilityScore":3.9,"impactScore":3.6}],"ssvcV203":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","ssvcData":{"timestamp":"2026-10-26T19:30:13.578600Z","id":"CVE-2026-115909","options":[{"exploitation":"none"},{"automatable":"yes"},{"technicalImpact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}]},"weaknesses":[{"source":"security-advisories@github.com","type":"Secondary","description":[{"lang":"en","value":"CWE-400"},{"lang":"en","value":"CWE-789"}]}],"references":[{"url":"https://github.com/zip-rs/zip2/commit/a543a1fc8f3f3eef36f27bb137230295284cdb98","source":"security-advisories@github.com"},{"url":"https://github.com/zip-rs/zip2/pull/984","source":"security-advisories@github.com"},{"url":"https://github.com/zip-rs/zip2/releases/tag/v9.0.0","source":"security-advisories@github.com"},{"url":"https://github.com/zip-rs/zip2/security/advisories/GHSA-q7v9-x93c-xqv3","source":"security-advisories@github.com"}]}
