Jul 15, 2026Grav 2.0.1 contains a decompression-bomb size-cap bypass in ZipArchiver and GPM\Installer.CVE-2026-61449 · Other software · getgrav · reported by VulnCheckHigh 7.1
Grav 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.

Where this comes from: the exploited list is CISA’s Known Exploited Vulnerabilities catalog. Everything else is the whole National Vulnerability Database, where each record is published by the team that found the bug (Wordfence, Patchstack, WPScan, the vendors themselves and others); we show who. Exploit odds are FIRST’s EPSS, updated daily. Titles and categories are ours, so check the linked record before acting on a detail. For a write-up of the big ones, see our advisories. Every vendor, and every WordPress plugin and theme with a recorded flaw, also has its own page. All of it is free to reuse as JSON, CSV or RSS.
