The defect exists in the add_reply function where the description_attachments parameter is not validated against a user\u2011controlled key. An authenticated user with subscriber-level privileges or higher can supply arbitrary attachment IDs, causing the system to re\u2011associate those files with the attacker\u2019s tickets and revoke the original owners\u2019 access. This results in unauthorized disclosure or removal of user\u2011uploaded documents, compromising confidentiality and potentially availability of attachments.", "risk_and_exploitability": "The CVSS score of 5.4 classifies the issue as moderate severity, but the EPSS score of less than 1% indicates a low exploitation probability at present. The vulnerability is not listed in the CISA KEV catalog, suggesting it has not yet been leveraged by large\u2011scale attackers. Exploitation requires authenticated access to the WordPress site with at least subscriber privileges, so the potential impact is confined to users who already have login capabilities. Nonetheless, the ability to steal and reallocate sensitive attachments warrants timely remediation."}}}}, "created": "2026-02-02T09:26:41.906063+00:00", "updated": "2026-04-16T01:30:20.310041+00:00", "vendors": ["psmplugins", "psmplugins$PRODUCT$supportcandy_\u2013_helpdesk_&_customer_support_ticket_system", "wordpress", "wordpress$PRODUCT$wordpress"]}
