A sandboxed plugin without the READ_FILES permission could read or write another plugin's directory that merely shares a name prefix (e.g., .../plugins/foobar matching allowed .../plugins/foo), breaking per-plugin isolation within the same user. Fixed by matching each allowed directory exactly or with a trailing path separator.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N","score":8.7},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N","score":5.2},"cwes":["CWE-22"],"references":["https://github.com/jahlives/openssl_encrypt/security/advisories/GHSA-vr4h-5xqv-xxxf","https://www.vulncheck.com/advisories/openssl-encrypt-before-1.4.9-plugin-sandbox-path-traversal"],"products":["jahlives:openssl_encrypt"],"source":"nvd","synced_at":"2026-10-19T22:50:17.453294893+00:00"},"epss":{"cve":"CVE-2026-81716","score":0.00261,"percentile":0.17928,"date":"2026-11-01"},"kev":null,"osv":[{"id":"PYSEC-2026-3800","url":"https://osv.dev/vulnerability/PYSEC-2026-3800","summary":"","modified":"2026-09-03T11:00:03.941389688Z","packages":[{"ecosystem":"PyPI","name":"openssl-encrypt","purl":"pkg:pypi/openssl-encrypt","ranges":["<1.4.9"],"fixed":["1.4.9"]}]}],"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).
