CVE-2025-52480
Registrator.jl Argument Injection Vulnerability
Registrator is a GitHub app that automates creation of registration pull requests for julia packages to the General registry. Prior to version 1.9.5, if the clone URL returned by GitHub is malicious (or can be injected using upstream vulnerabilities), an argument injection is possible in the gettreesha() function. This can then lead to a potential remote code execution. Users should upgrade immediately to v1.9.5 to receive a patch. All prior versions are vulnerable. No known workarounds are available.
