EchelonGraph scoreMEDIUM confidence

This medium-severity CVE scores 5.3 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.4%, top 67% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

A typo in the MISP ACLComponent access control configuration caused the ACL rule for the previewEventAttributes action to reference the permission string 'theming_enabled*' (with a trailing asterisk) instead of the correct 'theming_enabled'. In the MISP ACL system, the array values define which role or permission grants access to a given controller action. The adjacent entry previewEventObjects correctly uses ['theming_enabled'], confirming the intended restriction. The malformed key 'theming_enabled*' does not match any valid permission identifier, causing the access control check for previewEventAttributes to malfunction. Depending on the ACL evaluation logic, this could result in either unauthorized users gaining access to the previewEventAttributes endpoint (authorization bypass) or legitimate users being denied access (availability impact). 

The previewEventAttributes endpoint exposes event attribute data within MISP so an authorization bypass could expose sensitive indicator and attribute data to users who should not have access.
