Short explanation
Grav Lightbox Gallery plugin versions 1.1.0 through 1.3.2 contain an information disclosure vulnerability allowing server-readable YAML files to be read into a publicly viewable page via shortcode media actions.
This flaw allows an authenticated page editor to read and compromise sensitive information such as account password hashes, 2FA secrets, and API keys.
What should be done?
- Follow vendor security advisories
- Update the plugin to an unaffected version if available
- Restrict page editing privileges

Show the technical text from the sources
Grav Lightbox Gallery plugin 1.1.0 before 1.3.2 on Grav 2.x calls any medium method named in image, thumb or thumb_options shortcode values without core's allowed media action check. A page editor can chain addMetaFile with value, toYaml or toJson to read server-readable YAML files, such as account password hashes, 2FA secrets and API keys, into a publicly viewable page.
