{"apiVersion":"1.0","identifier":"CVE-2026-78680","description":"NLTK versions before 3.10.3 fail to use validated absolute paths when invoking the Graphviz dot binary in dependencygraph.dot2img and AlignedSent._repr_svg_, allowing attackers to execute arbitrary code by placing a malicious dot binary in the search path or current working directory. Attackers can exploit bare-name binary resolution on Windows via the current working directory or on Unix-like systems via relative PATH entries to execute their binary instead of the legitimate Graphviz tool.","publishedAt":"2026-08-25T02:16:52","lastModifiedAt":"2026-08-25T13:19:31","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-78680","cvssScore":7.8,"cvssVector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","epssProbability":0.0012,"riskScore":0.79,"affectedProduct":"NLTK","affectedVersions":"<3.10.3","vulnerabilityType":"Library","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-78680","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-78680","en":"https://www.redsauce.net/en/cves/CVE-2026-78680","fr":"https://www.redsauce.net/fr/cves/CVE-2026-78680","pt":"https://www.redsauce.net/pt/cves/CVE-2026-78680","de":"https://www.redsauce.net/de/cves/CVE-2026-78680","sk":"https://www.redsauce.net/sk/cves/CVE-2026-78680","el":"https://www.redsauce.net/el/cves/CVE-2026-78680"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-78680"}}
