In version 3.6.1 and earlier, HttpGet() in src/base/Http_win.cpp unconditionally passes INTERNET_FLAG_IGNORE_CERT_CN_INVALID to WinINet, disabling hostname matching for HTTPS update metadata and crash-symbol requests while retaining certificate-chain validation. A network-positioned attacker with a Windows-trusted certificate for an attacker-controlled domain can impersonate the project's update host, inject promo text and a clickable URL before update metadata validation, and provide an attacker-controlled archive to ExtractSymbols(). Installer replacement is not directly possible because HttpGetToFile() validates TLS and MaybeStartUpdateDownload() restricts the download host. No fixed version is available as of this review.\nhttps://www.cve.org/CVERecord?id=CVE-2026-115758https://github.com/sumatrapdfreader/sumatrapdf/security/advisories/GHSA-mjwr-9w29-jp96https://github.com/sumatrapdfreader/sumatrapdf/commit/bd30134175e897dd5ed0d7fd14acce52eeca7183#sumatrapdfreader #sumatrapdf#CVE_2026_115758#bot", "url": "https://infosec.exchange/users/cve/statuses/117560179586384243"}, {"timestamp": "2026-11-04T21:17:52.130Z", "date_only": false, "value": "2026-11-04T21:17:52.130", "kind": "milestone", "label": "Published", "source": "fkie_nvd \u00b7 FKIE_CVE-2026-115758", "record": "FKIE_CVE-2026-115758", "field": "published", "metric_role": "disclosure", "metric_basis": "recorded_event", "linked_record": true}, {"timestamp": "2026-11-09T16:09:29.752Z", "date_only": false, "value": "2026-11-09T16:09:29.752036Z", "kind": "other", "label": "Recorded", "source": "cvelistv5 / CISA-ADP", "record": "CVE-2026-115758", "field": "containers.adp.0.metrics.0.other.content.timestamp"}, {"timestamp": "2026-11-09T16:09:29.752Z", "date_only": false, "value": "2026-11-09T16:09:29.752036Z", "kind": "other", "label": "Recorded", "source": "fkie_nvd \u00b7 FKIE_CVE-2026-115758", "record": "FKIE_CVE-2026-115758", "field": "metrics.ssvcV203.0.ssvcData.timestamp", "linked_record": true}, {"timestamp": "2026-11-09T16:58:23.858Z", "date_only": false, "value": "2026-11-09T16:58:23.858Z", "kind": "other", "label": "Updated", "source": "cvelistv5", "record": "CVE-2026-115758", "field": "cveMetadata.dateUpdated"}, {"timestamp": "2026-11-09T16:58:23.858Z", "date_only": false, "value": "2026-11-09T16:58:23.858Z", "kind": "other", "label": "Updated", "source": "cvelistv5 / CISA-ADP", "record": "CVE-2026-115758", "field": "containers.adp.0.providerMetadata.dateUpdated"}, {"timestamp": "2026-11-09T17:17:11.807Z", "date_only": false, "value": "2026-11-09T17:17:11.807", "kind": "other", "label": "Updated", "source": "fkie_nvd \u00b7 FKIE_CVE-2026-115758", "record": "FKIE_CVE-2026-115758", "field": "lastModified", "linked_record": true}], "metrics": {"as_of": "2026-11-10T16:20:45.801Z", "anchors": {"origin": {"timestamp": "2026-11-04T20:44:55.316Z", "date_only": false, "value": "2026-11-04T20:44:55.316Z", "kind": "milestone", "label": "Published", "source": "cvelistv5", "record": "CVE-2026-115758", "field": "cveMetadata.datePublished", "metric_role": "disclosure", "metric_basis": "recorded_event"}, "discovery": null, "report": null, "acknowledgement": null, "disclosure": {"timestamp": "2026-11-04T20:44:55.316Z", "date_only": false, "value": "2026-11-04T20:44:55.316Z", "kind": "milestone", "label": "Published", "source": "cvelistv5", "record": "CVE-2026-115758", "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": 502550.485447, "hours": 139.5973570686111, "days": 5.816556544525463, "min_seconds": 502550.485447, "max_seconds": 502550.485447, "approximate": false, "ongoing": true, "order_known": true, "batch_listing": false, "end_before_start": false, "start": {"timestamp": "2026-11-04T20:44:55.316Z", "date_only": false, "value": "2026-11-04T20:44:55.316Z", "kind": "milestone", "label": "Published", "source": "cvelistv5", "record": "CVE-2026-115758", "field": "cveMetadata.datePublished", "metric_role": "disclosure", "metric_basis": "recorded_event"}, "end": {"timestamp": "2026-11-10T16:20:45.801Z", "date_only": false, "label": "As of", "source": "Calculation clock"}}, "exploitation_to_patch": {"available": false, "missing": ["start"]}, "exploit_publication_to_patch": {"available": false, "missing": ["start"]}}}
