Prior to 0.1.1, Pulpy injects a pulpy.fs JavaScript API into every packaged web application, giving it access to the host filesystem. A validateFsPath() function is supposed to sandbox this access, but its blocklist is incomplete. Any web app packaged with Pulpy can read and write arbitrary files in the user's home directory — including ~/.ssh/id_rsa, ~/.aws/credentials, and ~/Library/Keychains/. This vulnerability is fixed in 0.1.1.","published":"2026-05-12T20:16:43.000Z","lastModified":"2026-10-26T18:10:00.000Z","status":"Deferred","sourceIdentifier":"security-advisories@github.com","cvss":{"version":"3.1","score":9.3,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:N"},"cwe":["CWE-22","CWE-284"],"affected":[],"epss":{"score":0.01536,"percentile":0.74722,"date":"2026-10-27","history":[]},"kev":{"listed":false},"exploits":{"count":1,"verified":false,"firstPublished":"2026-07-06","source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[{"edbId":52616,"kind":"exploit","title":"Pulpy 0.1.1-Beta - Filesystem Sandbox Bypass","url":"https://www.exploit-db.com/exploits/52616","sourceUrl":"https://gitlab.com/exploit-database/exploitdb/-/blob/main/exploits/multiple/webapps/52616.txt","file":"exploits/multiple/webapps/52616.txt","published":"2026-07-06","added":"2026-07-06","updated":"2026-07-06","author":"Onur BILICI","type":"webapps","platform":"multiple","port":null,"verified":false,"codes":["CVE-2026-44225"],"tags":null,"aliases":null,"applicationUrl":null,"screenshotUrl":null,"referenceUrl":null}]},"verdict":{"level":"urgent","text":"A public exploit is published in Exploit-DB and the impact is critical, while EPSS rates exploitation at 1.5%.
