AI Analysis

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).

Affected Systems

Affected product is EspoCRM, all releases up to 9.3.10 and 10.0.10. The vulnerability resides in the file application/Espo/Tools/Pdf/Dompdf/ImageSourceProvider.php. No other versions are presently identified as impacted.

Risk and Exploitability

The vulnerability carries a CVSS score of 5.3, indicating a medium severity. No EPSS data is reported, so exploit likelihood is unknown but not documented. The issue is not listed in CISA’s KEV catalog. The attack can be carried out remotely by sending crafted requests that manipulate the ID value; no privileged system access is required. The exploit path exposes an unsecured method that lacks proper permission checks.

OpenCVE Recommended Actions

  • Apply the vendor patch referenced by commit 91a9edbcedb9c7aa8e3d3ac81d8a7acccb99bca2 which removes the vulnerability.
  • Add or enforce an authorization check in ImageSourceProvider::get to confirm the current user has permission to access the image resource before returning data.
  • Validate and sanitize the ID parameter so that only legitimate identifiers are accepted and reject any malformed or unauthorized values.
  • If the patch cannot be applied immediately, block external access to the PDF rendering endpoint until a fix is in place.
