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."}], "lastModified": "2025-10-08T19:16:13.530", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:mohammadzain2008:linkr:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "4DDC1998-F0FD-4AD3-B04A-6BB45FC84728", "versionEndExcluding": "2.0.1"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
