Prior to 0.1.9, bincookie_init_file() in bincookie.h allocates a buffer using the actual .binarycookies file length but trusts the file-controlled num_pages field as the loop bound for byte-swapping page_sizes entries. A crafted file can make the loop read and write beyond the heap allocation, and related unvalidated page sizes and cookie_offsets can drive additional out-of-bounds accesses in page and cookie iteration. Applications that parse an attacker-supplied binarycookies file may crash or suffer heap corruption that can potentially enable code execution. This issue is fixed in version 0.1.9.\nhttps://www.cve.org/CVERecord?id=CVE-2026-55246https://github.com/Tatsh/bincookie/security/advisories/GHSA-22pc-xxw4-q849https://github.com/Tatsh/bincookie/commit/bc1433c1ee4d0284750ff85c8437f1b8df91ab3bhttps://github.com/Tatsh/bincookie/releases/tag/v0.1.9#Tatsh #bincookie#CVE_2026_55246#bot", "url": "https://infosec.exchange/users/cve/statuses/117446089733911408"}, {"timestamp": "2026-10-15T18:17:27.317Z", "date_only": false, "value": "2026-10-15T18:17:27.317", "kind": "milestone", "label": "Published", "source": "fkie_nvd \u00b7 FKIE_CVE-2026-55246", "record": "FKIE_CVE-2026-55246", "field": "published", "metric_role": "disclosure", "metric_basis": "recorded_event", "linked_record": true}, {"timestamp": "2026-10-15T18:27:22.750Z", "date_only": false, "value": "2026-10-15T18:27:22.750510Z", "kind": "other", "label": "Recorded", "source": "cvelistv5 / CISA-ADP", "record": "CVE-2026-55246", "field": "containers.adp.0.metrics.0.other.content.timestamp"}, {"timestamp": "2026-10-15T18:27:22.750Z", "date_only": false, "value": "2026-10-15T18:27:22.750510Z", "kind": "other", "label": "Recorded", "source": "fkie_nvd \u00b7 FKIE_CVE-2026-55246", "record": "FKIE_CVE-2026-55246", "field": "metrics.ssvcV203.0.ssvcData.timestamp", "linked_record": true}, {"timestamp": "2026-10-15T18:27:40.897Z", "date_only": false, "value": "2026-10-15T18:27:40.897Z", "kind": "other", "label": "Updated", "source": "cvelistv5", "record": "CVE-2026-55246", "field": "cveMetadata.dateUpdated"}, {"timestamp": "2026-10-15T18:27:40.897Z", "date_only": false, "value": "2026-10-15T18:27:40.897Z", "kind": "other", "label": "Updated", "source": "cvelistv5 / CISA-ADP", "record": "CVE-2026-55246", "field": "containers.adp.0.providerMetadata.dateUpdated"}, {"timestamp": "2026-10-15T18:46:45.585Z", "date_only": false, "value": "2026-10-15T18:46:45.585106Z", "kind": "sighting", "label": "Seen", "source": "https://bsky.app/profile/thehackerwire.bsky.social/post/3mxwpw3jm472e", "record": "CVE-2026-55246", "field": "creation_timestamp", "uuid": "874d35f5-16c3-4d0b-a5cd-80831bbeb9a8", "content": "\ud83d\udfe0 CVE-2026-55246 - High (7.8)\n\nbincookie is a header-only binarycookies parser.
