By bypassing the intended access restrictions, an attacker could read or alter theme\u2011related configuration files, potentially revealing sensitive information tied to the service. The core weakness is a lack of proper privilege checks, aligning with CWE\u2011275. Consequently, the primary impact is a compromise of confidentiality, allowing disclosure of configuration details that may be used for further attacks.", "risk_and_exploitability": "The assigned CVSS score of 6.9 reflects a Moderate severity level, but the vulnerability is neither listed in CISA\u2019s KEV catalog nor associated with a known exploit probability metric. Based on the description, it is inferred that the attack vector requires local interaction with the theme manager or exploitation of unprotected API endpoints exposed to the user interface. Because no remote exploitation mechanism is expressly documented, the exploitation likelihood may be moderate. Prompt patching remains the most effective countermeasure."}}}}, "created": "2026-04-13T12:37:39.351943+00:00", "title": "Improper Permission Control in Huawei EMUI and HarmonyOS Theme Setting Module", "updated": "2026-04-13T12:53:26.801088+00:00", "vendors": ["huawei", "huawei$PRODUCT$emui", "huawei$PRODUCT$harmonyos"]}
