CVE-2026-118988 Details
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.
A path traversal vulnerability has been identified in CallBackery versions prior to 0.60.1 for Perl. This vulnerability allows unauthenticated clients to read the Plain Old Documentation (POD) of any file through the '/doc' route. Each CallBackery application loads its documentation plugin at '/doc', before any session checks are applied. The route improperly validates the requested file name, which is then passed to 'Pod::Simple::Search->find'. This function treats '::' as a path separator, enabling traversal out of the '@INC' directory. As a result, files readable by the server process can be accessed. Although only POD is rendered, files with a POD directive lacking a '=cut' will have POD content displayed up to the end of the file.
Upgrade to CallBackery version 0.60.1 or later.
