From versions 1.4.2 to before 1.4.5, and 1.5.0 to before 1.5.1, a signed fileStartPosition taken from AtomicReadFile and AtomicWriteFile stream-access requests is not validated tightly enough before it reaches the RAM file backends. Practical impact includes: reliable denial of service via process crash, out-of-bounds read that may expose adjacent memory contents, or out-of-bounds write that may corrupt heap memory and destabilize the process. This issue has been patched in versions 1.4.5 and 1.5.1.\nhttps://www.cve.org/CVERecord?id=CVE-2026-49990https://github.com/bacnet-stack/bacnet-stack/security/advisories/GHSA-8759-hx7g-94qxhttps://github.com/bacnet-stack/bacnet-stack/pull/1362#bacnet-stack#CVE_2026_49990#bot", "url": "https://infosec.exchange/users/cve/statuses/117609975924686355"}, {"timestamp": "2026-11-13T16:43:55.470Z", "date_only": false, "value": "2026-11-13T16:43:55.470366Z", "kind": "sighting", "label": "Seen", "source": "https://bsky.app/profile/cve.skyfleet.blue/post/fcerxfc2pe26e", "record": "CVE-2026-49990", "field": "creation_timestamp", "uuid": "766b0178-4f28-4ffa-b974-6fa945e2bbc2", "content": "CVE-2026-49990 - BACnet Stack: AtomicReadFile/AtomicWriteFile stream fileStartPosition validation flaw causes out-of-bounds read/write in RAM file backends\nCVE ID : CVE-2026-49990\n \n Published : Nov. 13, 2026, 3:54 p.m. | 20\u00a0minutes ago\n \n Description : BACnet Stack is a BACne...", "url": "https://bsky.app/profile/cve.skyfleet.blue/post/fcerxfc2pe26e"}], "metrics": {"as_of": "2026-11-13T21:18:41.775Z", "anchors": {"origin": {"timestamp": "2026-11-13T15:54:22.681Z", "date_only": false, "value": "2026-11-13T15:54:22.681Z", "kind": "milestone", "label": "Published", "source": "cvelistv5", "record": "CVE-2026-49990", "field": "cveMetadata.datePublished", "metric_role": "disclosure", "metric_basis": "recorded_event"}, "discovery": null, "report": null, "acknowledgement": null, "disclosure": {"timestamp": "2026-11-13T15:54:22.681Z", "date_only": false, "value": "2026-11-13T15:54:22.681Z", "kind": "milestone", "label": "Published", "source": "cvelistv5", "record": "CVE-2026-49990", "field": "cveMetadata.datePublished", "metric_role": "disclosure", "metric_basis": "recorded_event"}, "exploit_publication": null, "exploitation": null, "patch": null}, "vendor_response_time": {"available": false, "missing": ["start", "end"]}, "time_to_exploit": {"available": false, "missing": ["end"]}, "disclosure_to_exploit": {"available": false, "missing": ["end"]}, "disclosure_to_exploit_publication": {"available": false, "missing": ["end"]}, "time_to_patch": {"available": false, "missing": ["start", "end"]}, "total_time_to_patch": {"available": false, "missing": ["start", "end"]}, "disclosure_to_patch": {"available": false, "missing": ["end"]}, "time_unpatched": {"available": true, "seconds": 19459.094405, "hours": 5.405304001388889, "days": 0.22522100005787038, "min_seconds": 19459.094405, "max_seconds": 19459.094405, "approximate": false, "ongoing": true, "order_known": true, "batch_listing": false, "end_before_start": false, "start": {"timestamp": "2026-11-13T15:54:22.681Z", "date_only": false, "value": "2026-11-13T15:54:22.681Z", "kind": "milestone", "label": "Published", "source": "cvelistv5", "record": "CVE-2026-49990", "field": "cveMetadata.datePublished", "metric_role": "disclosure", "metric_basis": "recorded_event"}, "end": {"timestamp": "2026-11-13T21:18:41.775Z", "date_only": false, "label": "As of", "source": "Calculation clock"}}, "exploitation_to_patch": {"available": false, "missing": ["start"]}, "exploit_publication_to_patch": {"available": false, "missing": ["start"]}}}
