{"id":"DEBIAN-CVE-2026-53505","details":"Thumbor is an open-source photo thumbnail service by globo.com. Prior to 7.8.0, Thumbor's filters:proportion(\u003cvalue\u003e) filter does not enforce an upper bound on \u003cvalue\u003e and runs in the post-transform phase. An attacker can trigger extremely large resizes (CPU/memory exhaustion) and cause denial of service. This issue is fixed in 7.8.0.","modified":"2026-09-09T08:47:34.649598893Z","published":"2026-07-31T19:17:10.123Z","upstream":["CVE-2026-53505"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-53505"}],"affected":[{"package":{"name":"thumbor","ecosystem":"Debian:14","purl":"pkg:deb/debian/thumbor?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"7.8.0-1"}]}],"versions":["6.3.2-3","6.3.2-4","6.5.1-1","6.5.1-2","6.5.1-3","6.5.1-4","6.5.1-5","6.5.1-6","6.5.1-7","6.7.0-1","7.7.7-1","7.7.7-2","7.7.7-3","7.7.7-4","7.7.7-5","7.7.7-6"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-53505.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
