{"id":"CVE-2026-54448","summary":"Trivy: Helm chart tar bomb causes OOM via unbounded io.ReadAll in parser","details":"Trivy is a security scanner. Prior to 0.71.0, when Trivy scans a Helm chart archive (.tgz), its custom tar unpacker reads each entry with io.ReadAll(tr) and no size limit. An attacker who can place a malicious .tgz file in the scanned path can craft a small compressed archive that decompresses to gigabytes, causing the Trivy process to be killed by the OS OOM killer. This vulnerability is fixed in 0.71.0.","aliases":["GHSA-q3fv-x8vg-qqm4"],"modified":"2026-07-09T10:14:30.881661892Z","published":"2026-06-25T16:27:33.659Z","related":["openSUSE-SU-2026:11162-1","openSUSE-SU-2026:21249-1"],"database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-770","CWE-789"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/54xxx/CVE-2026-54448.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/54xxx/CVE-2026-54448.json"},{"type":"ADVISORY","url":"https://github.com/aquasecurity/trivy/security/advisories/GHSA-q3fv-x8vg-qqm4"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-54448"},{"type":"FIX","url":"https://github.com/aquasecurity/trivy/pull/10718"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/aquasecurity/trivy","events":[{"introduced":"0"},{"fixed":"9b49920eebb2bf648ba54211617d6078f6105594"}],"database_specific":{"cpe":"cpe:2.3:a:aquasec:trivy:*:*:*:*:*:go:*:*","extracted_events":[{"introduced":"0"},{"fixed":"0.71.0"}],"source":["AFFECTED_FIELD","CPE_RANGE"]}}],"versions":["v0.70.0","v0.69.0","v0.68.1","v0.68.0","v0.67.0","v0.66.0","v0.65.0","v0.64.0","v0.63.0","v0.62.0","v0.61.0","v0.60.0","v0.59.0","v0.58.0","v0.57.0","v0.56.0","v0.55.0","v0.54.0","v0.53.0","v0.52.0","v0.51.1","v0.51.0","v0.50.1","v0.50.0","v0.49.1","v0.49.0","v0.48.2","v0.48.1","v0.43.1","v0.48.0","v0.47.0","v0.46.0","v0.45.1","v0.45.0","v0.44.1","v0.44.0","v0.43.0","v0.42.1","v0.42.0","v0.41.0","v0.40.0","v0.39.1","v0.39.0","v0.38.3","v0.38.2","v0.38.1","v0.38.0","v0.37.3","v0.37.2","v0.37.1","v0.37.0","v0.36.1","v0.36.0","v0.35.0","v0.34.0","v0.33.0","v0.32.1","v0.32.0","v0.31.3","v0.31.2","v0.31.1","v0.31.0","v0.30.4","v0.30.3","v0.30.2","v0.30.1","v0.30.0","v0.29.2","v0.29.1","v0.29.0","v0.28.1","v0.28.0","v0.27.1","v0.27.0","v0.26.0","v0.25.4","v0.25.3","v0.25.2","v0.25.1","v0.25.0","v0.24.4","v0.24.3","v0.24.2","v0.24.1","v0.24.0","v0.23.0","v0.22.0","v0.21.3","v0.21.2","v0.21.1","v0.21.0","v0.20.2","v0.20.1","v0.20.0","v0.19.2","v0.19.1","v0.19.0","v0.18.3","v0.18.2","v0.18.1","v0.18.0","v0.17.2","v0.17.1","v0.17.0","v0.16.0","v0.15.0","v0.14.0","v0.13.0","v0.12.0","v0.11.0","v0.10.2","v0.10.1","v0.10.0","v0.9.2","v0.9.1","v0.9.0","v0.8.0","v0.7.0","v0.6.0","v0.5.4","v0.5.3","v0.5.2","v0.5.1","v0.5.0","v0.4.4","v0.4.3","v0.4.2","v0.4.1","v0.4.0","v0.3.1","v0.3.0","v0.2.1","v0.2.0","v0.1.7","v0.1.6","v0.1.5","v0.1.4","v0.1.3","v0.1.2","v0.1.1","v0.1.0","v0.0.16","v0.0.15","v0.0.14","v0.0.13","v0.0.12","v0.0.11","v0.0.10","v0.0.9","v0.0.8","v0.0.7","v0.0.6","v0.0.5","v0.0.4","v0.0.3","v0.0.2"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-54448.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N"}]}
