{"id":"CVE-2026-34586","summary":"PdfDing: Shared PDF Expiration, Max Views, and Deletion Bypass via Serve/Download Endpoints","details":"PdfDing is a selfhosted PDF manager, viewer and editor offering a seamless user experience on multiple devices. Prior to version 1.7.1, check_shared_access_allowed() validates only session existence — it does not check SharedPdf.inactive (expiration / max views) or SharedPdf.deleted. The Serve and Download endpoints rely solely on this function, allowing previously-authorized users to access shared PDF content after expiration, view limit, or soft-deletion. This issue has been patched in version 1.7.1.","aliases":["GHSA-vfqx-2464-38wf"],"modified":"2026-04-02T13:41:32.952244Z","published":"2026-03-31T20:27:50.597Z","database_specific":{"cwe_ids":["CWE-863"],"cna_assigner":"GitHub_M","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/34xxx/CVE-2026-34586.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/34xxx/CVE-2026-34586.json"},{"type":"FIX","url":"https://github.com/mrmn2/PdfDing/commit/a6783b259b25c839c52c6f2380333827a52e89eb"},{"type":"WEB","url":"https://github.com/mrmn2/PdfDing/releases/tag/v1.7.1"},{"type":"ADVISORY","url":"https://github.com/mrmn2/PdfDing/security/advisories/GHSA-vfqx-2464-38wf"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-34586"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/mrmn2/pdfding","events":[{"introduced":"0"},{"fixed":"66ffaf03db66f78b1af8f40c5c4d901ff9c560ec"}],"database_specific":{"versions":[{"introduced":"0"},{"fixed":"1.7.1"}]}}],"versions":["0.1.0","0.1.1","0.1.2","0.10.0","0.2.0","0.3.0","0.3.1","0.3.2","0.3.3","0.3.4","0.4.0","0.4.1","0.4.2","0.5.0","0.6.0","0.6.1","0.6.2","0.7.0","0.8.0","0.9.0","0.9.1","v0.11.0","v0.12.0","v0.12.1","v0.12.2","v0.12.3","v1.0.0","v1.1.0","v1.2.0","v1.2.1","v1.3.0","v1.3.1","v1.3.2","v1.3.3","v1.4.0","v1.4.1","v1.5.0","v1.5.1","v1.6.0","v1.6.1","v1.6.2","v1.6.3","v1.7.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-34586.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N"}]}
