Prior to 0.11.10, the apps/readest-app/src/pages/api/storage/upload.ts route constructed an object key from the authenticated user's identifier and a client-controlled fileName without rejecting path separators or parent-directory traversal. In the R2 backend, apps/readest-app/src/utils/r2.ts placed that key into a new Request URL before signing it, and URL normalization collapsed parent-directory components so the resulting presigned PUT could escape the caller's namespace. An authenticated attacker who knew a target user identifier and book hash could overwrite or poison that user's stored book object and corrupt the associated file_key metadata; the exact cross-tenant escape was verified for the R2 backend. This issue is fixed in version 0.11.10.\nhttps://www.cve.org/CVERecord?id=CVE-2026-57565https://github.com/readest/readest/security/advisories/GHSA-mfmj-2frf-vhgwhttps://github.com/readest/readest/pull/4638https://github.com/readest/readest/commit/495783d04516d05b2eb10f8f8bad297d436b36dehttps://github.com/readest/readest/releases/tag/v0.11.10#readest#CVE_2026_57565#bot", "url": "https://infosec.exchange/users/cve/statuses/117560386018714667"}, {"timestamp": "2026-11-04T22:18:06.680Z", "date_only": false, "value": "2026-11-04T22:18:06.680", "kind": "milestone", "label": "Published", "source": "fkie_nvd \u00b7 FKIE_CVE-2026-57565", "record": "FKIE_CVE-2026-57565", "field": "published", "metric_role": "disclosure", "metric_basis": "recorded_event", "linked_record": true}, {"timestamp": "2026-11-05T20:05:26.746Z", "date_only": false, "value": "2026-11-05T20:05:26.746679Z", "kind": "other", "label": "Recorded", "source": "cvelistv5 / CISA-ADP", "record": "CVE-2026-57565", "field": "containers.adp.0.metrics.0.other.content.timestamp"}, {"timestamp": "2026-11-05T20:05:26.746Z", "date_only": false, "value": "2026-11-05T20:05:26.746679Z", "kind": "other", "label": "Recorded", "source": "fkie_nvd \u00b7 FKIE_CVE-2026-57565", "record": "FKIE_CVE-2026-57565", "field": "metrics.ssvcV203.0.ssvcData.timestamp", "linked_record": true}, {"timestamp": "2026-11-05T20:11:46.274Z", "date_only": false, "value": "2026-11-05T20:11:46.274Z", "kind": "other", "label": "Updated", "source": "cvelistv5", "record": "CVE-2026-57565", "field": "cveMetadata.dateUpdated"}, {"timestamp": "2026-11-05T20:11:46.274Z", "date_only": false, "value": "2026-11-05T20:11:46.274Z", "kind": "other", "label": "Updated", "source": "cvelistv5 / CISA-ADP", "record": "CVE-2026-57565", "field": "containers.adp.0.providerMetadata.dateUpdated"}, {"timestamp": "2026-11-05T20:17:58.740Z", "date_only": false, "value": "2026-11-05T20:17:58.740", "kind": "other", "label": "Updated", "source": "fkie_nvd \u00b7 FKIE_CVE-2026-57565", "record": "FKIE_CVE-2026-57565", "field": "lastModified", "linked_record": true}], "metrics": {"as_of": "2026-11-08T14:49:54.558Z", "anchors": {"origin": {"timestamp": "2026-11-04T21:45:21.130Z", "date_only": false, "value": "2026-11-04T21:45:21.130Z", "kind": "milestone", "label": "Published", "source": "cvelistv5", "record": "CVE-2026-57565", "field": "cveMetadata.datePublished", "metric_role": "disclosure", "metric_basis": "recorded_event"}, "discovery": null, "report": null, "acknowledgement": null, "disclosure": {"timestamp": "2026-11-04T21:45:21.130Z", "date_only": false, "value": "2026-11-04T21:45:21.130Z", "kind": "milestone", "label": "Published", "source": "cvelistv5", "record": "CVE-2026-57565", "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": 320673.42886, "hours": 89.0759524611111, "days": 3.711498019212963, "min_seconds": 320673.42886, "max_seconds": 320673.42886, "approximate": false, "ongoing": true, "order_known": true, "batch_listing": false, "end_before_start": false, "start": {"timestamp": "2026-11-04T21:45:21.130Z", "date_only": false, "value": "2026-11-04T21:45:21.130Z", "kind": "milestone", "label": "Published", "source": "cvelistv5", "record": "CVE-2026-57565", "field": "cveMetadata.datePublished", "metric_role": "disclosure", "metric_basis": "recorded_event"}, "end": {"timestamp": "2026-11-08T14:49:54.558Z", "date_only": false, "label": "As of", "source": "Calculation clock"}}, "exploitation_to_patch": {"available": false, "missing": ["start"]}, "exploit_publication_to_patch": {"available": false, "missing": ["start"]}}}
