Prior to 0.7.2, packages/oci/src/registry.ts contains a RegistryClient.signIn() method that stores registry Authorization and Docker configuration headers as defaults on a shared HTTP client, while RegistryClient.uploadBlob() sends a fresh PUT to an absolute blob-upload Location supplied by the registry without checking that its origin or scheme matches the registry. A malicious or compromised registry can therefore direct a user pushing an artifact through attachArtifactToImage() to an attacker-controlled host and receive the registry bearer token, Basic credentials, or custom authentication headers. Redirect-time header stripping does not prevent the leak because the cross-host PUT is a new explicit request rather than a followed redirect. This is a residual of CVE-2026-59891, whose fix changed credential selection in credentials.ts but did not constrain where credentials are sent from registry.ts. Version 0.7.2 fixes the issue by separating registry credentials from client-wide defaults and sending them only to the registry origin.\nhttps://www.cve.org/CVERecord?id=CVE-2026-118763https://github.com/sigstore/sigstore-js/security/advisories/GHSA-j63v-mwhm-56jxhttps://github.com/sigstore/sigstore-js/pull/1762https://github.com/sigstore/sigstore-js/commit/b855f46cfe81f26481c6d3f4b333dfd00f2fd1b1https://github.com/sigstore/sigstore-js/commit/e4ca65c3ab3c675456ab9b0bd04217ceccad3558https://github.com/sigstore/sigstore-js/releases/tag/@sigstore/oci@0.7.2#sigstore #sigstore-js#CVE_2026_118763#bot", "url": "https://infosec.exchange/users/cve/statuses/117525507307450927"}], "metrics": {"as_of": "2026-11-01T01:02:38.633Z", "anchors": {"origin": {"timestamp": "2026-07-14T16:54:50.608Z", "date_only": false, "value": "2026-07-14T16:54:50.608Z", "kind": "milestone", "label": "Published", "source": "cvelistv5", "record": "CVE-2026-59891", "field": "cveMetadata.datePublished", "metric_role": "disclosure", "metric_basis": "recorded_event"}, "discovery": null, "report": null, "acknowledgement": null, "disclosure": {"timestamp": "2026-07-14T16:54:50.608Z", "date_only": false, "value": "2026-07-14T16:54:50.608Z", "kind": "milestone", "label": "Published", "source": "cvelistv5", "record": "CVE-2026-59891", "field": "cveMetadata.datePublished", "metric_role": "disclosure", "metric_basis": "recorded_event"}, "exploit_publication": {"timestamp": "2026-07-29T00:00:13.180Z", "date_only": false, "value": "2026-07-29T00:00:13.180715Z", "kind": "sighting", "label": "Published proof of concept", "source": "Telegram/h1j6Jl6m2npLlEniyRpMllHKNmi9d2U9i1x7gM3I-76diKo", "record": "CVE-2026-59891", "field": "creation_timestamp", "uuid": "d51a9edb-def3-4f48-9a67-c4f72ceee00e", "metric_role": "exploit_publication", "metric_basis": "sighting_report"}, "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": true, "seconds": 1235122.572, "hours": 343.0896033333333, "days": 14.295400138888889, "min_seconds": 1235122.572, "max_seconds": 1235122.572, "approximate": false, "ongoing": false, "order_known": true, "batch_listing": false, "end_before_start": false, "start": {"timestamp": "2026-07-14T16:54:50.608Z", "date_only": false, "value": "2026-07-14T16:54:50.608Z", "kind": "milestone", "label": "Published", "source": "cvelistv5", "record": "CVE-2026-59891", "field": "cveMetadata.datePublished", "metric_role": "disclosure", "metric_basis": "recorded_event"}, "end": {"timestamp": "2026-07-29T00:00:13.180Z", "date_only": false, "value": "2026-07-29T00:00:13.180715Z", "kind": "sighting", "label": "Published proof of concept", "source": "Telegram/h1j6Jl6m2npLlEniyRpMllHKNmi9d2U9i1x7gM3I-76diKo", "record": "CVE-2026-59891", "field": "creation_timestamp", "uuid": "d51a9edb-def3-4f48-9a67-c4f72ceee00e", "metric_role": "exploit_publication", "metric_basis": "sighting_report"}}, "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": 9446868.025223, "hours": 2624.130007006389, "days": 109.33875029193287, "min_seconds": 9446868.025223, "max_seconds": 9446868.025223, "approximate": false, "ongoing": true, "order_known": true, "batch_listing": false, "end_before_start": false, "start": {"timestamp": "2026-07-14T16:54:50.608Z", "date_only": false, "value": "2026-07-14T16:54:50.608Z", "kind": "milestone", "label": "Published", "source": "cvelistv5", "record": "CVE-2026-59891", "field": "cveMetadata.datePublished", "metric_role": "disclosure", "metric_basis": "recorded_event"}, "end": {"timestamp": "2026-11-01T01:02:38.633Z", "date_only": false, "label": "As of", "source": "Calculation clock"}}, "exploitation_to_patch": {"available": false, "missing": ["start"]}, "exploit_publication_to_patch": {"available": true, "seconds": 8211745.453223, "hours": 2281.0404036730556, "days": 95.04335015304399, "min_seconds": 8211745.453223, "max_seconds": 8211745.453223, "approximate": false, "ongoing": true, "order_known": true, "batch_listing": false, "end_before_start": false, "start": {"timestamp": "2026-07-29T00:00:13.180Z", "date_only": false, "value": "2026-07-29T00:00:13.180715Z", "kind": "sighting", "label": "Published proof of concept", "source": "Telegram/h1j6Jl6m2npLlEniyRpMllHKNmi9d2U9i1x7gM3I-76diKo", "record": "CVE-2026-59891", "field": "creation_timestamp", "uuid": "d51a9edb-def3-4f48-9a67-c4f72ceee00e", "metric_role": "exploit_publication", "metric_basis": "sighting_report"}, "end": {"timestamp": "2026-11-01T01:02:38.633Z", "date_only": false, "label": "As of", "source": "Calculation clock"}}}}
