In versions 5.0.0 through 5.0.22, 6.0.0 through 6.0.18, 7.0.0 through 7.0.18, and 8.0.0 through 8.0.8, bad clients that always send a fixed batch value when the server is using the acknowledgement extension may cause the unacknowledged message queue to grow indefinitely, eventually causing an `OutOfMemoryError`. Versions 5.0.23, 6.0.19, 7.0.19, and 8.0.9 patch the issue. As a workaround, disable the acknowledgement extension.","published_at":"2026-06-18T16:25:47.388000Z","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":null,"ssvc_automatable":null,"ssvc_technical_impact":null,"cwes":["CWE-400"],"nvd_references":["https://github.com/cometd/cometd/security/advisories/GHSA-cqgj-h8vf-4w59","https://github.com/cometd/cometd/issues/2117","https://github.com/cometd/cometd/pull/2118","https://github.com/cometd/cometd/pull/2168","https://github.com/cometd/cometd/pull/2169","https://github.com/cometd/cometd/discussions/2116"],"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":"2026-06-28T23:27:28.114987Z"},"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":"cometd","vendor_name":"cometd","product_slug":"cometd","product_name":"cometd","version_start":">= 5.0.0, < 5.0.23","version_start_inclusive":true,"version_end":">= 5.0.0, < 5.0.23","version_end_inclusive":true,"cpe23_uri":"cve5:cometd:cometd:>= 5.0.0, < 5.0.23:>= 5.0.0, < 5.0.23"},{"vendor_slug":"cometd","vendor_name":"cometd","product_slug":"cometd","product_name":"cometd","version_start":">= 6.0.0, < 6.0.19","version_start_inclusive":true,"version_end":">= 6.0.0, < 6.0.19","version_end_inclusive":true,"cpe23_uri":"cve5:cometd:cometd:>= 6.0.0, < 6.0.19:>= 6.0.0, < 6.0.19"},{"vendor_slug":"cometd","vendor_name":"cometd","product_slug":"cometd","product_name":"cometd","version_start":">= 7.0.0, < 7.0.19","version_start_inclusive":true,"version_end":">= 7.0.0, < 7.0.19","version_end_inclusive":true,"cpe23_uri":"cve5:cometd:cometd:>= 7.0.0, < 7.0.19:>= 7.0.0, < 7.0.19"},{"vendor_slug":"cometd","vendor_name":"cometd","product_slug":"cometd","product_name":"cometd","version_start":">= 8.0.0, < 8.0.9","version_start_inclusive":true,"version_end":">= 8.0.0, < 8.0.9","version_end_inclusive":true,"cpe23_uri":"cve5:cometd:cometd:>= 8.0.0, < 8.0.9:>= 8.0.0, < 8.0.9"}],"exploit_refs":[],"news":[],"references":[{"url":"https://github.com/cometd/cometd/security/advisories/GHSA-cqgj-h8vf-4w59","source_type":"VENDOR_ADVISORY","tags":["advisory"]},{"url":"https://github.com/cometd/cometd/issues/2117","source_type":"MISC","tags":[]},{"url":"https://github.com/cometd/cometd/pull/2118","source_type":"PATCH","tags":["patch"]},{"url":"https://github.com/cometd/cometd/pull/2168","source_type":"PATCH","tags":["patch"]},{"url":"https://github.com/cometd/cometd/pull/2169","source_type":"PATCH","tags":["patch"]},{"url":"https://github.com/cometd/cometd/discussions/2116","source_type":"MISC","tags":[]}],"timeline":[{"type":"published","at":"2026-06-18T16:25:47.388000Z","label":"CVE published","source":null},{"type":"cvss_changed","at":"2026-06-28T17:47:31.968567Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:47:31.968567Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:47:31.968567Z","label":"CVSS score revised","source":"cvelistv5"}]}
