CVE-2026-118988
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.
Executive briefing
The source record describes: 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. The practical risk depends on whether an affected product/version is present, reachable and configured in an exploitable way. Review the affected-product evidence and linked vendor advisories before assigning exposure status.

Severity & attack characteristics
CVSS vector:CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N
Technical explanation & impact
The technical mechanism is not expanded beyond the source description unless a referenced advisory supplies additional evidence. Read the linked vendor/CERT advisories for root-cause detail.
Potential impact must be interpreted from the published CVSS impact metrics and the affected component. A CVSS impact score is not proof that a particular asset is exploitable.
Weakness classification
CWE-22Affected products and versions
NVD has not supplied machine-readable vulnerable CPE product/version entries for this CVE. This is an information gap, not proof that no products are affected. Check the vendor advisory references below.
Remediation & validation
- Identify exposure by comparing the affected product and version ranges with your asset inventory, SBOM and externally exposed services.
- Review the linked vendor security advisory or patch notes. Upgrade to a vendor-confirmed fixed release; do not infer a fixed version from the CVE description.
- Until patched, consider restricting network access or disabling the affected feature where operationally safe. These are temporary controls, not a substitute for a vendor fix.
- Validate the remediation with a version check and vulnerability rescan, then retain change evidence.
No fixed version is displayed unless it is explicitly established by a vendor advisory. Follow the vendor's release notes for exact product and branch applicability.
