Prior to version 1.30.0, the mailpit dump --http <base-url> <out-dir> sub-command downloads every message from a remote Mailpit instance and writes each one as <id>.eml inside the user-supplied output directory. The message ID field is taken verbatim from the JSON response of the remote server and concatenated into the output path with path.Join, which silently normalizes `..` segments. A malicious HTTP server impersonating Mailpit can therefore make mailpit dump write attacker-controlled bytes to any path the running user can write, fully outside the intended output directory. Version 1.30.0 contains a patch."}], "lastModified": "2026-07-28T15:30:44.933", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:axllent:mailpit:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "3ECED29B-387E-4170-B0E7-1818C63ADB60", "versionEndExcluding": "1.30.0"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
