In affected versions, a low-privileged authenticated `NETCONF` user can remotely crash `netopeer2-server` by sending a `get RPC` with an invalid `subtree filter` whose text contains format specifiers. In `src/netconf.c`, `np2srv_rpc_get_cb()` sends the invalid value through `ERR()` to `np2log_printf()`, where `vsnprintf()` first formats the message safely. In `src/log.c`, that already formatted buffer is subsequently passed to `np2log()` as the format string itself, causing `vsyslog()` to interpret attacker-controlled percent sequences and read invalid pointer arguments. The reported denial of service was confirmed on version 2.8.7 using `NETCONF`-over-SSH and AddressSanitizer; reliable remote code execution was not confirmed. `The advisory identifies 2.8.8 as patched`; repository comparisons verify the fix in public release 2.8.21. The affected/fixed boundary remains unresolved because no public 2.8.8 tag was located, which does not establish the status of an untagged 2.8.8 build.\nhttps://www.cve.org/CVERecord?id=CVE-2026-63201https://github.com/CESNET/netopeer2/security/advisories/GHSA-25gm-4x89-7r2qhttps://github.com/CESNET/netopeer2/commit/e98beb2d4d8cc82875208bccb8e1348a8e9e95b3https://github.com/CESNET/netopeer2/releases/tag/2.8.21#CESNET #netopeer2#CVE_2026_63201#bot", "url": "https://infosec.exchange/users/cve/statuses/117532165984690107"}, {"timestamp": "2026-10-30T22:16:58.637Z", "date_only": false, "value": "2026-10-30T22:16:58.637", "kind": "milestone", "label": "Published", "source": "fkie_nvd \u00b7 FKIE_CVE-2026-63201", "record": "FKIE_CVE-2026-63201", "field": "published", "metric_role": "disclosure", "metric_basis": "recorded_event", "linked_record": true}, {"timestamp": "2026-11-02T17:03:24.936Z", "date_only": false, "value": "2026-11-02T17:03:24.936130Z", "kind": "other", "label": "Recorded", "source": "cvelistv5 / CISA-ADP", "record": "CVE-2026-63201", "field": "containers.adp.0.metrics.0.other.content.timestamp"}, {"timestamp": "2026-11-02T17:03:24.936Z", "date_only": false, "value": "2026-11-02T17:03:24.936130Z", "kind": "other", "label": "Recorded", "source": "fkie_nvd \u00b7 FKIE_CVE-2026-63201", "record": "FKIE_CVE-2026-63201", "field": "metrics.ssvcV203.0.ssvcData.timestamp", "linked_record": true}, {"timestamp": "2026-11-02T18:08:38.871Z", "date_only": false, "value": "2026-11-02T18:08:38.871Z", "kind": "other", "label": "Updated", "source": "cvelistv5", "record": "CVE-2026-63201", "field": "cveMetadata.dateUpdated"}, {"timestamp": "2026-11-02T18:08:38.871Z", "date_only": false, "value": "2026-11-02T18:08:38.871Z", "kind": "other", "label": "Updated", "source": "cvelistv5 / CISA-ADP", "record": "CVE-2026-63201", "field": "containers.adp.0.providerMetadata.dateUpdated"}, {"timestamp": "2026-11-02T19:35:33.347Z", "date_only": false, "value": "2026-11-02T19:35:33.347", "kind": "other", "label": "Updated", "source": "fkie_nvd \u00b7 FKIE_CVE-2026-63201", "record": "FKIE_CVE-2026-63201", "field": "lastModified", "linked_record": true}], "metrics": {"as_of": "2026-11-05T18:46:01.905Z", "anchors": {"origin": {"timestamp": "2026-10-30T22:03:18.551Z", "date_only": false, "value": "2026-10-30T22:03:18.551Z", "kind": "milestone", "label": "Published", "source": "cvelistv5", "record": "CVE-2026-63201", "field": "cveMetadata.datePublished", "metric_role": "disclosure", "metric_basis": "recorded_event"}, "discovery": null, "report": null, "acknowledgement": null, "disclosure": {"timestamp": "2026-10-30T22:03:18.551Z", "date_only": false, "value": "2026-10-30T22:03:18.551Z", "kind": "milestone", "label": "Published", "source": "cvelistv5", "record": "CVE-2026-63201", "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": 506563.354176, "hours": 140.71204282666667, "days": 5.863001784444444, "min_seconds": 506563.354176, "max_seconds": 506563.354176, "approximate": false, "ongoing": true, "order_known": true, "batch_listing": false, "end_before_start": false, "start": {"timestamp": "2026-10-30T22:03:18.551Z", "date_only": false, "value": "2026-10-30T22:03:18.551Z", "kind": "milestone", "label": "Published", "source": "cvelistv5", "record": "CVE-2026-63201", "field": "cveMetadata.datePublished", "metric_role": "disclosure", "metric_basis": "recorded_event"}, "end": {"timestamp": "2026-11-05T18:46:01.905Z", "date_only": false, "label": "As of", "source": "Calculation clock"}}, "exploitation_to_patch": {"available": false, "missing": ["start"]}, "exploit_publication_to_patch": {"available": false, "missing": ["start"]}}}
