Prior to 2.0.0-alpha.4, a path traversal vulnerability in Ferret's IO::FS::WRITE standard library function allows a malicious website to write arbitrary files to the filesystem of the machine running Ferret. When an operator scrapes a website that returns filenames containing ../ sequences, and uses those filenames to construct output paths (a standard scraping pattern), the attacker controls both the destination path and the file content. This can lead to remote code execution via cron jobs, SSH authorized_keys, shell profiles, or web shells. This vulnerability is fixed in 2.0.0-alpha.4.","state":0,"publishedAt":"2026-04-06T17:17:10.43+00:00","modifiedAt":"2026-10-23T23:10:00.157+00:00","affected":[],"metrics":[{"system":"CVSS 3.1 · security-advisories@github.com · Secondary","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:H","score":8.1,"severity":"HIGH"}],"references":["https://github.com/MontFerret/ferret/commit/160ebad6bd50f153453e120f6d909f5b83322917","https://github.com/MontFerret/ferret/security/advisories/GHSA-j6v5-g24h-vg4j"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-34783","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Analyzed","weaknesses":["CWE-22","CWE-73"],"productCriteria":["cpe:2.3:a:montferret:ferret:*:*:*:*:*:go:*:*","cpe:2.3:a:montferret:ferret:2.0.0:alpha1:*:*:*:go:*:*","cpe:2.3:a:montferret:ferret:2.0.0:alpha2:*:*:*:go:*:*","cpe:2.3:a:montferret:ferret:2.0.0:alpha3:*:*:*:go:*:*"],"sourceDates":{"published":"2026-04-06T17:17:10.430","lastModified":"2026-10-23T23:10:00.157"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
