In versions prior to 1.22.1 secompressors accumulate decompressed data into an intermediate buffer before overwriting the body in the decode/encodeBody. This may allow an attacker to zip bomb the decompressor by sending a small highly compressed payload. Maliciously constructed zip files may exhaust system memory and cause a denial of service. Users are advised to upgrade. Users unable to upgrade may consider disabling decompression.","published_at":"2022-06-09T19:15:14Z","last_modified_at":null,"cvss_v3_score":7.5,"cvss_v3_vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","cvss_v3_severity":"HIGH","cvss_v4_score":null,"cvss_v4_vector":null,"cvss_v4_severity":null,"ssvc_decision":null,"ssvc_exploitation":"poc","ssvc_automatable":true,"ssvc_technical_impact":"partial","cwes":["CWE-400","CWE-409"],"nvd_references":["https://github.com/envoyproxy/envoy/security/advisories/GHSA-75hv-2jjj-89hh","https://github.com/envoyproxy/envoy/commit/cb4ef0b09200c720dfdb07e097092dd105450343"],"vuln_status":null,"trending_score":null,"is_trending":false,"has_trended":false,"trended_number_one":false,"trending_peak_score":null,"trending_peak_rank":null,"started_trending_at":null,"trended_number_one_at":null,"summary_generated":null,"summary_generated_at":null,"summary_model":null,"created_at":"2026-06-24T00:09:39.878444Z","updated_at":"2026-06-29T01:03:11.180710Z"},"effective_severity":"HIGH","badges":[],"impact_analysis":[],"cvss_v3_decoded":{"version":"3.1","metrics":[{"metric":"AV","name":"Attack Vector","value":"N","value_label":"Network"},{"metric":"AC","name":"Attack Complexity","value":"L","value_label":"Low"},{"metric":"PR","name":"Privileges Required","value":"N","value_label":"None"},{"metric":"UI","name":"User Interaction","value":"N","value_label":"None"},{"metric":"S","name":"Scope","value":"U","value_label":"Unchanged"},{"metric":"C","name":"Confidentiality","value":"N","value_label":"None"},{"metric":"I","name":"Integrity","value":"N","value_label":"None"},{"metric":"A","name":"Availability","value":"H","value_label":"High"}]},"cvss_v4_decoded":{"version":null,"metrics":[]},"affected":[{"vendor_slug":"envoyproxy","vendor_name":"envoyproxy","product_slug":"envoy","product_name":"envoy","version_start":"< 1.22.1","version_start_inclusive":true,"version_end":"< 1.22.1","version_end_inclusive":true,"cpe23_uri":"cve5:envoyproxy:envoy:< 1.22.1:< 1.22.1"}],"exploit_refs":[],"news":[],"references":[{"url":"https://github.com/envoyproxy/envoy/security/advisories/GHSA-75hv-2jjj-89hh","source_type":"VENDOR_ADVISORY","tags":["advisory"]},{"url":"https://github.com/envoyproxy/envoy/commit/cb4ef0b09200c720dfdb07e097092dd105450343","source_type":"PATCH","tags":["patch"]}],"timeline":[{"type":"published","at":"2022-06-09T19:15:14Z","label":"CVE published","source":null},{"type":"cvss_changed","at":"2026-06-28T17:22:08.449389Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:22:08.449389Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:22:08.449389Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"ssvc_changed","at":"2026-06-29T01:03:11.180710Z","label":"SSVC decision revised","source":"vulnrichment"},{"type":"ssvc_changed","at":"2026-06-29T01:03:11.180710Z","label":"SSVC decision revised","source":"vulnrichment"},{"type":"ssvc_changed","at":"2026-06-29T01:03:11.180710Z","label":"SSVC decision revised","source":"vulnrichment"}]}
