{"id":"CVE-2025-59334","summary":"Linkr allows manifest tampering leading to arbitrary file injection","details":"Linkr is a lightweight file delivery system that downloads files from a webserver. Linkr versions through 2.0.0 do not verify the integrity or authenticity of .linkr manifest files before using their contents, allowing a tampered manifest to inject arbitrary file entries into a package distribution. An attacker can modify a generated .linkr manifest (for example by adding a new entry with a malicious URL) and when a user runs the extract command the client downloads the attacker-supplied file without verification. This enables arbitrary file injection and creates a potential path to remote code execution if a downloaded malicious binary or script is later executed. Version 2.0.1 adds a manifest integrity check that compares the checksum of the original author-created manifest to the one being extracted and aborts on mismatch, warning if no original manifest is hosted. Users should update to 2.0.1 or later. As a workaround prior to updating, use only trusted .linkr manifests, manually verify manifest integrity, and host manifests on trusted servers.","aliases":["GHSA-6wph-mpv2-29xv"],"modified":"2026-04-02T12:56:48.570125Z","published":"2025-09-16T16:48:34.887Z","database_specific":{"cwe_ids":["CWE-347"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/59xxx/CVE-2025-59334.json","cna_assigner":"GitHub_M"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/59xxx/CVE-2025-59334.json"},{"type":"ADVISORY","url":"https://github.com/mohammadzain2008/Linkr/security/advisories/GHSA-6wph-mpv2-29xv"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-59334"},{"type":"FIX","url":"https://github.com/mohammadzain2008/Linkr/commit/182e5ddaa51972e144005b500c4bcebf2fd1a6c0"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/mohammadzain2008/linkr","events":[{"introduced":"0"},{"fixed":"b9dd61181303985f1a514beb8c4eeaaf019b9897"}]}],"versions":["v0.1.0-alpha","v1.0.0","v2.0.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2025-59334.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H"}]}
