In cases where PDF text objects are present it is possible to copy-paste redacted information into the system clipboard. Once a document is \"locked\" and marked for redaction once, all redactions performed after this feature is triggered are vulnerable.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","score":7.5},"cwes":["CWE-116","CWE-1116"],"references":["https://arxiv.org/pdf/2206.02285.pdf","https://www.pdfzorro.com/pdf-edit/","https://arxiv.org/pdf/2206.02285.pdf","https://www.pdfzorro.com/pdf-edit/"],"products":["pdfzorro:pdfzorro"],"source":"nvd","synced_at":"2026-10-19T21:37:48.383111019+00:00"},"epss":{"cve":"CVE-2022-30351","score":0.00565,"percentile":0.46953,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
