Impact
A bug in EspoCRM’s PDF Rendering Pipeline in versions up to 9.3.10 and 10.0.10 allows a remote attacker to manipulate the ID argument passed to ImageSourceProvider::get. This results in an authorization bypass, letting the attacker retrieve image data that should be protected. The flaw is a classic authorization flaw (CWE‑285) combined with user‑controlled key misuse (CWE‑639).
