Prior to 0.18.1, when pattern-based ACL rules are configured, AuthorizationsCollector.canDoOperation substitutes client ID and username values directly into rules containing %c or %u and then treats the result as an MQTT topic filter. A client that uses + or # in either identity can broaden the substituted filter and gain cross-tenant read and write access. A # identity can also produce an invalid filter that triggers a NullPointerException in Topic.match and disrupts session processing. This issue is fixed in version 0.18.1."}], "lastModified": "2026-09-25T13:34:57.140", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:moquette:moquette:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "3C13C0A2-7D78-4742-8861-54D487319A82", "versionEndExcluding": "0.18.1"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
