CVE-2026-76902

Name of the Vulnerable Software and Affected Versions CordysCRM versions prior to 1.7.4

Description ShiroFilter configures the endpoints '/attachment/preview/{id}' and '/pic/preview/{id}' as anonymous. Both routes call the getResource() function in AttachmentService, which performs a primary-key lookup without verifying ownership, organization, or permissions. An unauthenticated caller can download files uploaded by users from other organizations by guessing or observing an id generated by IDGenerator.nextStr, as the stored organization id is used only for file location rather than caller authorization.

Recommendations Update to version 1.7.4.
