The size bound introduced in 2.0.1 sums the uncompressed size declared in each entry's ZIP central-directory header (ZipArchive::statIndex()['size']) and rejects archives exceeding system.gpm.archive.max_uncompressed_size before extraction. Because this declared size is attacker-forgeable and is not cross-checked against the actual inflated stream, a crafted archive declaring tiny per-entry sizes passes the cap while extractTo() writes the real, much larger content, filling disk or exhausting inodes. The archive must be supplied by a package source or admin upload (admin/operator trust). Fixed in 2.0.2. This is an incomplete fix for GHSA-928x-9mpw-8h56.","state":0,"publishedAt":"2026-07-15T11:25:43.802+00:00","modifiedAt":"2026-10-08T15:23:32.555+00:00","affected":[{"ecosystem":"Vendor product","name":"grav","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"getgrav\",\n                    \"product\": \"grav\",\n                    \"defaultStatus\": \"unaffected\",\n                    \"versions\": [\n                        {\n                            \"version\": \"0\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"semver\",\n                            \"lessThan\": \"2.0.2\"\n                        },\n                        {\n                            \"version\": \"2.0.2\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        }\n                    ],\n                    \"packageURL\": \"pkg:composer/getgrav/grav\"\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","score":7.1,"severity":"HIGH"},{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H","score":6.5,"severity":"MEDIUM"}],"references":["https://github.com/getgrav/grav/security/advisories/GHSA-8h9x-89f2-m7x3","https://www.vulncheck.com/advisories/grav-before-decompression-bomb-via-forged-zip-size"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-61449","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-61449","identifiers":["CVE-2026-61449"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
