This link is maintained to preserve external references.\n\n### Original Description\nGrav 2.0.1 contains a decompression-bomb size-cap bypass in ZipArchiver and GPM\\Installer. 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.","public_affected_ranges":[]}],"null_published_at":"2026-10-31T22:12:38.460Z","source_updated_at":"2026-09-17T15:00:05.906Z","source_disclosed_at":"2026-07-15T12:32:04.000Z","is_synthetic_fixture":false,"null_last_reviewed_at":null,"public_change_summary":"First indexed by Null; source disclosure date is shown separately.","null_first_observed_at":"2026-10-31T21:42:41.370Z"}],"next_cursor":null,"snapshot_revision":"42594"}
