Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Reposilite versions 3.3.0 up to 3.5.12 are vulnerable to path traversal during javadoc archive expansion, where filenames inside the archive can point outside the target directory. An attacker who publishes a crafted javadoc archive to an upstream repository that Reposilite mirrors, such as Maven Central, can cause the server to overwrite arbitrary local files without credentials, potentially leading to code execution. Upgrade to Reposilite 3.5.12.
