CWE-200: Exposure of Sensitive Information to an Unauthorized Actor
Reaching this weakness in article2pdf 0.24 – 0.27 · 4 branches takes a caller who can reach the endpoint. Sensitive information exposure means data the application intended to keep internal is returned to a caller who should not be able to see it.
The disclosed data — credentials, tokens, customer records or internal paths — is usually worth more as material for a follow-up attack than as an end in itself. No fixed build of this plugin is recorded for article2pdf yet, so installs running 0.24 – 0.27 · 4 branches stay exposed until the vendor ships one.
