CallBackery versions before 0.60.1 for Perl let unauthenticated clients read the POD of any file via path traversal in the /doc route

Impact

CallBackery for Perl, versions before 0.60.1, allows unauthenticated clients to read the POD of any file via path traversal in the /doc route. The vulnerability occurs due to a lack of validation in the documentation plugin. Any file the server process can read is potentially reachable.

Summarized by @cf/meta/llama-3.3-70b-instruct-fp8-fast. Verify details against the original sources.

What to do

Upgrade to CallBackery 0.60.1 or later.

Original source description

CallBackery versions before 0.60.1 for Perl let unauthenticated clients read the POD of any file via path traversal in the /doc route.

Every CallBackery application mounts its documentation plugin at /doc, ahead of any session check. The route passes the requested name to Pod::Simple::Search->find without validation. find splits the name on "::" and joins the parts into a file path, so a name such as "..::..::..::etc::motd" escapes @INC.

Any file the server process can read is reachable. Only POD is rendered, but a file with a POD directive and no "=cut" is POD to the end of the file.
