{"id":"CVE-2026-82068","summary":"Persistent Fatal Assertion Crash in MongoDB Server via Crafted Retryable Write Commands Leads to Denial of Service","details":"A security issue in MongoDB Server allows an authenticated user with write privileges to trigger a persistent fatal assertion crash by sending specially crafted retryable write commands. The crash state is durably persisted, causing the server process to repeatedly crash on restart and potentially propagating to additional nodes in a sharded cluster. Manual intervention is required to restore service availability.","aliases":["BIT-mongodb-2026-82068"],"modified":"2026-09-18T08:11:08.881230Z","published":"2026-09-08T16:12:27.566Z","database_specific":{"cna_assigner":"mongodb","cwe_ids":["CWE-617"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/82xxx/CVE-2026-82068.json","unresolved_ranges":[{"source":"AFFECTED_FIELD","extracted_events":[{"introduced":"8.3.0"},{"fixed":"8.3.9"},{"introduced":"8.0.0"},{"fixed":"8.0.30"},{"introduced":"7.0.0"},{"fixed":"7.0.41"}]}]},"references":[{"type":"WEB","url":"https://jira.mongodb.org/browse/SERVER-131326"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/82xxx/CVE-2026-82068.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-82068"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/mongodb/mongo","events":[{"introduced":"37d84072b5c5b9fd723db5fa133fb202ad2317f1"},{"fixed":"6df23543fc9e7ee456ff05ed726b22865ea753e7"},{"introduced":"b41cda4fe697dce6fd9b83b3805362ccc02fbeb3"},{"fixed":"11c3ed7c274d5fb7149e498323bd0377c3a2876e"},{"introduced":"0f29b043a58fdd251ce0a0b32754b8459613c933"},{"fixed":"1dc3d60c3237b53589325474c668e849ecec3bae"}],"database_specific":{"cpe":"cpe:2.3:a:mongodb:mongodb:*:*:*:*:-:*:*:*","extracted_events":[{"introduced":"7.0.0"},{"fixed":"7.0.41"},{"introduced":"8.0.0"},{"fixed":"8.0.30"},{"introduced":"8.3.0"},{"fixed":"8.3.9"}],"source":"CPE_RANGE"}}],"versions":["r7.0.35","r8.0.24","r8.3.3","r8.3.0","r7.0.27-rc0","r7.0.27","r8.0.17-alpha0","r8.0.16-rc1","r8.0.16","r7.0.27-alpha0","r7.0.26-rc0","r7.0.26","r8.0.16-rc0","r8.0.14-rc1","r8.0.14","r7.0.24-rc0","r7.0.24","r7.0.25-alpha0","r8.0.14-rc0","r8.0.13-rc2","r8.0.13","r8.0.13-rc1","r8.0.13-rc0","r7.0.23-rc1","r7.0.23","r7.0.23-rc0","r7.0.22-rc0","r7.0.22","r8.0.12-rc0","r8.0.12","r8.0.10-rc0","r8.0.10","r7.0.21-rc0","r7.0.21","r7.0.21-alpha0","r7.0.18","r8.0.6","r7.0.17","r8.0.5-rc2","r8.0.5","r8.0.5-rc1","r8.0.5-rc0","r7.0.16-rc1","r7.0.16-rc0","r7.0.16","r8.0.4-rc0","r8.0.4","r7.0.15","r8.0.3","r8.0.2","r7.0.15-rc1","r7.0.15-rc0","r8.0.1-rc0","r8.0.1","r8.0.0","r7.0.14-rc0","r7.0.14","r7.0.13-rc1","r7.0.13","r7.0.13-rc0","r7.0.12-rc1","r7.0.12","r7.0.12-rc0","r7.0.11-rc2","r7.0.11","r7.0.11-rc1","r7.0.11-rc0","r7.0.10-rc0","r7.0.10","r7.0.9-rc1","r7.0.9","r7.0.9-rc0","r7.0.8-rc0","r7.0.8","r7.0.7-rc2","r7.0.7","r7.0.7-rc1","r7.0.7-rc0","r7.0.6-rc0","r7.0.6","r7.0.5-rc0","r7.0.5","r7.0.4-rc0","r7.0.4","r7.0.3-rc1","r7.0.3","r7.0.3-rc0","r7.0.2-rc2","r7.0.2","r7.0.2-rc1","r7.0.2-rc0","r7.0.1-rc0","r7.0.1","r7.0.0"],"database_specific":{"vanir_signatures_modified":"2026-09-18T08:11:08Z","vanir_signatures":[{"id":"CVE-2026-82068-7518edcc","signature_type":"Line","signature_version":"v1","source":"https://github.com/mongodb/mongo/commit/11c3ed7c274d5fb7149e498323bd0377c3a2876e","target":{"file":"src/mongo/util/observable_mutex_registry.cpp"},"deprecated":false,"digest":{"line_hashes":["66908565863182878949263117251652046873","81045179624099588995371526936867447218","40887363166120728720864979839570738440","256732394880312722171336173841003327192","189479856184880563329078480903896694545","175148206283301428432002867622286913085","305665546638865113923099657246304323513"],"threshold":0.9}},{"digest":{"function_hash":"97328004591881352222915931748724594831","length":772},"id":"CVE-2026-82068-77577a26","signature_type":"Function","signature_version":"v1","source":"https://github.com/mongodb/mongo/commit/6df23543fc9e7ee456ff05ed726b22865ea753e7","target":{"file":"src/mongo/db/pipeline/document_source_list_catalog.cpp","function":"DocumentSourceListCatalog::createFromBson"},"deprecated":false},{"digest":{"line_hashes":["165410231648936824589980198196954162537","136501663843339022690751043996234207290","285354211900527027711069075030245862327","118881528740665335694743800161340085998","36266064472550105418329813861525007356","16931947150780577515020757191522828473"],"threshold":0.9},"id":"CVE-2026-82068-ba1994eb","signature_type":"Line","signature_version":"v1","source":"https://github.com/mongodb/mongo/commit/6df23543fc9e7ee456ff05ed726b22865ea753e7","target":{"file":"src/mongo/db/pipeline/document_source_list_catalog.h"},"deprecated":false},{"target":{"file":"src/mongo/db/pipeline/document_source_list_catalog.cpp"},"deprecated":false,"digest":{"threshold":0.9,"line_hashes":["15118513725026685067664956440423785894","4881464334735159279508803095757659276","266758334235923098891166228361922998690","287039910505335082692569496912566155170","215343628858689419312915919625353446408","80950900741330922061414046051663341667","48699755411854371597904640594615452680","299434378678909034395123214857676742507","320443038501231526517453934170620795671","37185450870766536639064978090208934675","330071214781083562802997609052830790317","112905490564973162584994830096370086935"]},"id":"CVE-2026-82068-c539edfe","signature_type":"Line","signature_version":"v1","source":"https://github.com/mongodb/mongo/commit/6
