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.","published":"2026-08-27T17:21:01.877","modified":"2026-08-27T17:21:01.877","cvss":{"score":5.2,"severity":"MEDIUM","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://github.com/jahlives/openssl_encrypt/security/advisories/GHSA-vr4h-5xqv-xxxf"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/openssl-encrypt-before-1.4.9-plugin-sandbox-path-traversal"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-08-27T17:21:01.877"}}
